Chinese in space homemade chips for the first time for the Beidou navigation

　　Zhao Fu teams in research.

　　Profile picture

　　Turn into bustling Beijing South central axis, entered a yard next to the China Academy of launch vehicle technology, was suddenly quiet a lot. Sycamore green, research building in picturesque disorder. Here, by the China Aerospace Science and Technology Corporation 772 Director Zhao Fu team developed the domestic CPU chip, was first used in a new generation on the Beidou navigation satellite. To this day, Zhao Yuan-fu and his team more than 10 years.

　　The Beidou aerospace-grade CPU chip made products has reached the international advanced level of performance. "In certain indicators of radiation resistance, more than foreign products, we also have an advantage. "Zhao Yuanfu said confidently.

　　A road

　　Core chips related to information security, to master core technologies can only take the road of independent research and development

　　Zhao Yuanfu is Jinxian, Jiangxi people, when he was a cowboy, he's been curious why transistor radio made a noise, when I was in College, he chose professional semiconductor physics and devices. In 1983, Zhao Yuanfu Huang Chang, a famous aerospace microelectronic technology in China under the guidance of study for a master's degree, began working in radiation technology, from then on, his anti-radiation technologies are increasingly recognizing the important role of national space development. "The core technology is unable to rely on others, which is the Foundation. "Zhao Yuanfu recalled.

　　Information security is a national strategy, the hardware support is the core chip. At present, the chip relies mainly on imports, chip in each of China's imports would cost more than 200 billion dollars, and the cost of imported oil. Chips for space applications, but also has the special properties of radiation. Because the space environment is extremely complex, massive space particle radiation can cause performance degradation on the stars and even failure, fatal blow to satellites.

　　"But in addition to the astronauts, who have not gone into space. "The problems that may be encountered in space on Earth make it clear that difficulties can be imagined.

　　Chips, common people use cell phones and other electronic products are known as "electronics industry". Chips used on spacecraft to withstand the test of the harsh space environment, because of their special needs are called "sectors". In 1996, Zhao Yuanfu got a chance to study abroad, after two years of study, he clearly saw the huge gap radiation technology at home and abroad. Foreign instructors to provide job opportunities, Zhao Yuanfu eventually chose to return home, for him, to return home without an answer, since the choice of developing "China chip" have to go to the end.

　　"This has been hailed as the brain and heart of the satellite guy, embodies the heart of China's space technology. "Zhao Yuanfu proudly said," in order to achieve autonomous control of a China Aerospace chip, no matter how difficult it is, we have got to do something. "

　　A major problem

　　Persist more than a decade, only to overcome design difficulties, low-cost development of anti-radiation chip

　　Anti-radiation to make aviation chip, what should I do? have a way in the past--to the circuit and put on thick "coat", but this would increase weight significantly; in addition, you can also try changing the manufacturing process, but such investment is huge. How to cost effectively develop anti-radiation chip and become puzzle scientists all over the world.

　　After his return in 1998, Zhao Yuanfu led the team to study the star component of radiation-resistant characteristics and causes of backward, in 1999, he offered a low-cost "reinforcement design" idea that reinforcement of integrated circuit technology developed by using only IC production lines for civilian use, design and non-manufacturing sectors will develop radiation space integrated circuits.

　　Thus, radiation-resistant difficulties moved to the chip design, and anti-radiation chip design is a global problem. Zhao yuanren team first started working for two or three years, never figure things out. In order to create highly reliable "China chip" anti-radiation chip 772 passes through the ground under simulated space radiation environment experiment and evaluation. To complete more of the radiation experiments, team members need to get vacuum sealed cans, replace just finished radiation testing samples to prepare for the next round of tests. And time radiation testing typically takes at least 24 hours, or even days uninterrupted. In order to test the "seamless", members of the team are hungry to eat instant noodles, sleepy floor, continuous watch dozens of hours, became the norm.

　　Firm, stick, stick to just quietly waiting for ten years in radiation technology, Zhao Yuan-fu and his team published more than 600 scientific papers in radiation technology, obtained more than 200 patents. Now, 772 has built a unique rad hard IC development platform in China.

　　A dream

　　To be independent not imitation, as life's work space, independent research and development can always find a way

　　"Look up at the stars, but also down to Earth." "The Chinese" shines in space, Zhao Yuan-fu and his team first select "the Crown Diamond"-central processing unit as a core research products for technical applications of radiation resistance.

　　Targeting early in development in our own research and international a new generation of space used on the CPU, rather than go the way of imitation, Zhao Fu thoughtfully, "we like out, having been upgraded CPU came out, generic products have no competitive advantage. "

　　The central processing unit, looking only the thumbnail size, but has a brain complex and fine. Due to the early stage of research and development, international a new generation of CPU and there is no practical products for aerospace, only general ideas and concepts, nearly everything from scratch. "Starting from our study on the anti-radiation technique of counting, since 15 years. Starting from this project, it is also ten years rubs a sword. "When you talk about the frustrations of the first China-made CPU development process, Zhao Yuanfu said light wind," the aerospace industry gathered a group of scientists, they have as their life's work space and perseverance, can always find a way out. " Liu Shuwei PK TV plus traditional and Internet

　　Zhao yuanren team developed the homemade CPU, not only for higher speeds, variable interface type more and more and more suited to different functional components of the satellite needs. "A domestic space with the CPU, not only to get the chip itself, to build ' chip + software + environment ' localization pattern. "" The Chinese ", Zhao yuanren rich a more profound consideration.

　　Therefore, "the Chinese" is getting better. Apart from the CPU, and data bus circuits on the Beidou, converters, memory, nearly 40 772 for the development and production of products, which is a satellite system for the first time used Chinese-made chips, for independent control of aerospace engineering and innovation development milestone. "Satellites in spite of complete. "Zhao Yuanfu smiled," only the establishment of independent and complete product system, can let the satellite high-reliability operation more secure. "

　　Not only that, 772 development of IC for Aerospace also received foreign orders. From the original "Introduction" to the present "go", Zhao Yuanfu looking forward to witness the important crossing of China Aerospace microelectronic development.

What products do not have native APP development micro signal to the public

　　

 

　　Most recent phase H5 technology is pushed to the peak, a lot of people believed H5 can be the use of the letter public, replace the APP native apps, but what is? I from doing an objective analysis.

　　A native APP overall trends

　　To talk about whether the APP would be replaced by micro-letter, you have to go back and look at the whole APP growth, mobile distribution market report released as early as 2014, Baidu, Android market growth is slowing, dividends are disappearing.

　　And objective view tools APP development was bottlenecked saturation tools do APP is done. The rest of the APP is built around content production with social networking and news APP, and this is the test business potential energy.

　　Conclusion: now, APP development, in order to get into a pure tools and intelligent hardware or line the opportunity to combine the APP does not exist, followed by content-type APP require strong operational capabilities. So in this case, we're discussing first is utility class APP can migrate to the micro-credit services,? the second type is the content of this type of operation can be migrated to micro-credit services,?

　　Second, the native APP in four quadrants and micro-letters

　　Now from the user and open a four-quadrant frequency to discuss native APP, this quadrant represents the requirements that already exist, how many users here based on BAT matrix product line, we set off from the four quadrants to see micro-services, and the corresponding relationship.

　　

 

　　Number of users, frequency: this type of APP is to BAT matrix product, is impossible in micro-credit services, BAT also will consider next BAT-level micro-letter service, company will not be born, must open up the Hill. So there is no chance.

　　User less low frequency: this type of APP is our common products that small is beautiful in the app store, some small creative products, the APP itself is not too big a chance, so I did not have the chance, to service. Because demand has been verified.

　　User less frequently: this APP is similar to take a taxi to the last drop, onsite laundry, massage and more. APP is also referred to as user take a taxi here compared to the reason for the decline is because the app and QQ BAT matrix products, taxi software is installed the number is small, compared to any other vertical service APP from the BAT matrix product is small. But this class APP has a opportunities is using micro-letter of service, put himself put to inside, for user provides service, such both saves has high of development cost, and reduced has high of user gets cost, imagine, now let user to to Gets a service and to download APP has more difficult, and now to push also main is let user scan micro-letter service, II dimension code, but if said to online Xia let user scan II dimension code download APP, this scene is very not reasonable of, Because the vast majority of scenarios without WIFI. Micro-credit services, there have been a lot of O2O services, hotel reservations, car washes, door-to-door service, and so on. But the app itself is on the one hand, micro purse took a taxi into the drop, as well as booking train tickets and airline tickets, and so on, O2O products compete with micro-there is a risk in the future, but currently don't have to worry about, you must first expand eligibility after the talk.

　　Vertical social products, this type of APP is inappropriate to do so in the public? the answer is micro-community itself is a vertical social networking APP, vertical social networking is essentially a forum, and the micro-micro-communities has been involved in many vertical are using micro-communities, public forum. Itself, but everything on the premise that the public has a very powerful impact, otherwise it is meaningless. When the volume reaches a certain scale of these micro-communities of users, you can immediately niaoqianghuanpao, such as the public, "Mermaid line VS vest lines", first in public, there is a huge fan of micro-communities, and then developed APP from the app. Micro communities only BBS, can extend functionality is not enough, and the user is not in their hands, it is investors don't want to see. Micro-communities can exist as a springboard, of course, also depends on whether the team had jumped out of the power.

　　Number of users, frequency: this type of APP are the basic tools APP, like any mobile phone factory will bring their own calculator APP, calendar APP, APP notes, alarm clock APP, the APP the user scale is almost even with the BAT matrix products is much more. But the APP is not high on the frequency in use, such as how often do people tend to use a calendar? but will open the app and QQ a day.

　　So I would like to address is that these have a certain user base but not high frequency migrating APP to app will work. So first discussion a feasible of is "prepared forget reminded" class APP, dang you has what need notification if has a service, can directly let you meet this needs is very good of, you only need into service,, then set prepared forget reminded on can has, but micro-letter team is very smart of, they also early found has this needs can achieved so do has a "voice reminded" for has sniper, the service, can directly through voice set prepared forget reminded, than any entered operation are convenient. This APP can do service, only a small minority, not all APP have the opportunity, if the native APP migration to the service number are discussed below, then how does APP will app design?

　　Third, the primary tools migrating APP to app, conditions of service

　　Here come from talk about user experience, native tools APP move to micro-credit services, what conditions are required.

　　Conditions, from the aspect of products must be at a more convenient, more efficient basis, such as "accounting software" active operation of this product, do not fit, because users use the app actually increased operating costs, but once a product's operation costs, it will die.

　　Primary action:

　　Original opening: find the APP for the mobile phone interface-> open APP-> directly corresponds to fixed position operation

　　Primary switches: layer switching-> operation Huawei executives of their entrepreneurial dreams

　　Micro-service operation:

　　Micro-credit services, open app search service or line-by-line found on the top->,-> clicks into service menu, or push messages link at the bottom to enter H5-> operation

　　Micro-switch, service:->*, from service users has the potential to jump out of the app, so you may need to switch to the micro-> micro top searches, or line-by-line, find public-> public->, click menu or push messages link at the bottom to enter H5-> operation

　　The second condition, according to the conditions of a launch, many native APP users active operation in micro-breaks of service, is the increased cost of operations, so migrating primary tools in this APP to app doesn't work, migrating native APP to app more is needed to meet user demand for passive, or "push is greater than the active" this APP may have a fighting chance.

　　Conditions, according to the limited launch app, this APP app open interface conditions must be met, push can be done, but similar WIFI assistants, cleaning memory service can't do, because the app does not provide the corresponding interface. But remind the class can, micro-services, offering 500,000 pushing customer service response times the specified user interface (when the APP pushes the cloud), as well as the user's unique OpenID for an interface, then you may be.

　　Conclusions: increased user costs native APP is absolutely not suitable for this type of access to micro-credit services. Primary tools APP migration services must meet, 1, to push the leading. 2, followed by the app interface conditions.

　　So some service, worth attempts to, does not necessarily can success but has must opportunities, voice reminded (micro-letter has do), mail reminded and reply (Tencent Enterprise mailbox has do), friends birthday reminded, major schedule countdown reminded, PM2.5 alert reminded, constellation shipped drive reminded, team collaboration push sent reminded, exercise reminded, water reminded, medicine reminded and so on itself consider, but to believes Tencent aspects not fool, must also in consider this aspects of service, products, in you do zhiqian to wants to clear you of accumulated resources whether enough ? Then if the app screen your circle of friends sharing links how to do? that is the real problem.

　　Conclusion:

　　Last summary, take force micro-letter service, and H5 technology can do three class native tool APP, first class is low frequency O2O service class, second class is to a public, for core of vertical social, third class is "push sent" logic of original health tool APP, and this class APP Tencent aspects has in to layout, due to cost not high, this three class are in little achieved.

　　So one thing to judge beyond apart from watching the trend, going back to specific scenes, although H5 rise, but a new technique to subvert, remains to be seen whether the user is in a real world scenario to bring higher efficiency, rather than speculation.

Next generation solar aircraft in Switzerland debut

　　Solar-powered aircraft "solar impulse" design planning of local time on Wednesday formally announced its new plane, the distance of its global flight plan is a one-year period. "Solar Impulse 2" as a follow-up to the original aircraft models, using the same name as the original aircraft, and the aircraft in the unused fuel was completed last year across the United States sailing.

　　Both aircraft are is by far the most power-efficient aircraft design. First prototype pilots, a flying laboratory, "Solar Impulse 2" is a bigger, better version of its predecessor, its wingspan of 72 meters. Although the same wingspan as the A380 aircraft, but it was below the 1% of the A380 aircraft, only 2,300 kilograms. The aircraft weighs less than 25 g/m² carbon fibre laminates manufactured, weight is only a piece of paper 1/3. The aircraft will be in the wing and fuselage lay the 17,248 solar cells to provide power, with the aim of at least 120 hours no stop flight around the world.

　　That starts next month in Switzerland after flight testing, plans at some time after March 1, 2015, under ideal weather conditions, took off from the Gulf stream to a certain position, flying to the East, and will take at least five days of time to fly from China to the United States and from the United States to fly back to Europe. Officials say, although it cannot compete with traditional airline, but the focus of the project is to promote green aviation research.

　　Aircraft designers struggle with the problem that more reliable technologies tend to be more severe, but the weight means worse performance. In addition, other problems are to be solved, when the plane is flying over the ocean at an altitude of 8000 meters how to ensure the safety of the pilots. Zhou hongyi subversion of the pioneering first

　　"Solar impulse" aircraft project has been launched in more than 10 years ago, and the traditional aircraft manufacturers to seriously consider. When the "solar impulse" plane 12 years ago when it was put in the design of computer can see the huge wingspan and the light weight of the structure, all the world's aviation experts began a foolish laugh at now, real existence of the aircraft.

　　The first "solar impulse" aircraft began flying in 2009. The next year, the record it hit a 26-hour flight, proves it can store enough energy for night flights during the day. Last year across the United States before the flight, the aircraft had flown through Europe, and across the Eastern Mediterranean to Morocco.

Mobile phone into the water do it lets you carry your phone a bath

　　Impervious

　　Since Nokia's acquisition by Microsoft, after mass layoffs in the country, "fell into the water three months up you can still use" Nokia God machine became a joke in the user memories. Compare Nokia, iPhone waterproof performance has become the focus of much criticism. Especially in the heat of the summer, people are keen on visiting the summer in forest wetlands, how can we play at the water's edge, I did not get wet cell phone, becomes difficult.

　　Impervious

　　Impervious the Los Angeles team is a waterproofing spray specially designed for iPhone, which uses nanotechnology, mobile surface to form a layer of invisible protective film.

　　IPhone users need to be Impervious spray on the body spray, which uses advanced nano-technology special liquids will be attached to cell phones or flat surface. Because the spray is 1000 times smaller than the human hair nano materials, thin films formed by very thin, cannot be seen with the naked eye.

　　Spray formed protective film can make iPhone in under 1 meter of water soak for 30 minutes can also continue to use, and spray are valid for 3 years, meaning that in 3 years can waterproof effect.

　　Impervious

　　Other than waterproof and Impervious also has a scratch-proof role, in experiments on the Kickstarter video as you can see, after the spray is sprayed with a knife in the draw on the cell phone, cell phone screen does not leave traces.

　　Impervious suitable for all models of iPhone, iPad, and Android phones are also available. Now the Nano waterproof spray has been obtained from the United States raised platform completed on Kickstarter to raise total raised $ 54,762, exceeding the set target of 7,500. Sells for $ 39, about 244 Yuan.

　　Earlier, on a raised platform in the country also has a RELIWELL raise the spray, the Nano waterproof spray developed by a startup team, Hangzhou, Zhejiang, in addition to electronic products, the team also stresses the product can be used in shoes, cars, waterproof protection on the tray.

　　Experience in using a process called RELIWELL has smell of bananas, water, questions about its safety. But the team responded by saying that spraying is not a fossil products, toxic than alcohol. Global robot industry first Japan lead China us

Rare Appears on the Sun Tour Eiffel like prominences

　　According to foreign media reports, at present, Sweden photographer Gora-strand (Goran Strand) Eiffel Tower tonguelike structure in the shape of the Sun's surface has been observed.

　　A large arc-shaped strand later observed the sun hot gas extending thousands of kilometers from the Sun's surface into space, even more wonderful is, astronomers observed solar prominence is very similar to the Eiffel Tower. Strand described this prominence has two "support", placed on the surface of the Sun, "the tower" from the surface of the Sun, extending into space.

　　He in accept reporter interview Shi said: "I often in sunny using small portable Sun telescope watch Sun, observation whether appeared some makes I interested in of changes, Sun surface active sex daily are in changes among, on this I very curious! due to this prominence structure very big, immediately attract has I of attention, I in Sweden Ernie sitesongde area home in the Hou garden research has a will, zhihou decided on it for shooting. "At present, take the strand of the Sun's surface" Eiffel "7 times larger than the Earth. It is learnt that the strand began in 1995 to shoot the sky scene, 2012 to become a full-time photographer. From car to rail independence of large aircraft

Domestic hundred of MeV Proton cyclotron developed

    On July 4, outside the core group of the China Institute of Atomic Energy cyclotron laboratory targets appear on the screen of a bright blue-white beam, marking from the independent research and development of successful first 100 MeV Proton cyclotron beam. Thus, China has become one of the few countries with the next generation of radioactive nuclear beam accelerator. Experts point out that technologies in the fields of nuclear medicine and Radiology has a wide range of applications, it is expected to bring new breakthrough for early diagnosis and treatment of cancer. 2015 world s brightest top 50 companies Ali millet

    Cyclotron Chief Designer Zhang Tianjue introduced the 100 MeV Proton cyclotron 6.16 meters in diameter, is the largest international compact, high current Proton cyclotron, was developed by our independent innovation, the highest energy Proton cyclotron. Successful development of the accelerator, shows that our master large ultra-precision magnetic technology, high stability of high frequency technology, high speed and low temperature Proton cyclotron vacuum technology and a number of core technologies, and made a series of innovative results.

    Accelerator is an important platform for nuclear science, measurement of Neutron Physics and nuclear data, proton irradiation effects of unstable nuclear, new nuclide syntheses, structures, research on biological effects of protons, and so on, and in the development of nuclear technology and isotope production and nuclear medicine is widely used. For example, a cyclotron to produce different kinds of radioactive nuclides, including PET super short-lived radionuclides, can be used for early diagnosis of cancer and cardiovascular disease. After completion of the 100 MeV Proton cyclotron, can produce dozens of radioactive isotopes, will enable more species-rich radioisotopes for medical use.

    It is understood that this new technology will also be used for development of the cyclotron for proton therapy. Radiation therapy is one of the important means of cancer treatment, compared with x-ray and electron beam irradiation, high utilization of Proton dose, distribution, and normal tissue injury, side effects, so the "attack" cancer cells at the same time maximum protection of human normal tissues. Because proton therapy radiation dose can be exact to the 3D position of cerebral gliomas have a significant advantage. Related statistics show that the effective rate is higher than 90%, with 5-year survival rate is higher than 80%.
