Such modifications to enumerate sand

QianYongGang helps me, the most important is in historical facts verification.
For example, qian xuesen's mother died year, there are all kinds of parlance, some say 1935 qian xuesen to after the United States, some lami chapa shoes say 1947 qian xuesen, still have the wedding eve returned even said qian xuesen's mother attended the 1947 summer in Shanghai sand Hudson building (now the peace hotel) held with the JiangYing qian xuesen wedding.
At first, QianYongGang said to me, for his money home understand better, for his grandma chapter house details of the unclear. He knows only father 1935 to study in the United States, my grandma has died. Later, he after verification, tell me his grandmother died in 1935 summer. He was based access the home material, to check his grandmother in hangzhou grave photos, engraved with who died in republic of twenty-four years summer , namely 1935 summer.
Be like again, in the United States is how to send qian xuesen to ChenShuTong vice-chairman of the letter, qian xuesen ever had the Chinese people's liberation army will rank and so on a series of historical research, has been QianYongGang help.
On sensitive issues of repeatedly consideration
I noticed, qian xuesen have also been various query , among them the most outstanding is the per WanJin food and human paranormal two questions. Things originally not complex, but after repeated magnifying and after embellish, became qian xuesen's two big imperfection .
I in writing biographies, always claim not avoid sensitive issue. I also found that these two issues qian xuesen never do explanation, it is more firmness of my idea.
These two problems, 2009 April 12 QianYongGang in came to my house, he studied together. At that time, don't write QianYongGang advocated the withdrawal. He thinks, the first written down,Three as to whether published, when published, again appropriately.
In the near qian xuesen in, I wrote from dispute see qian xuesen chapter, about 4 million words. I expect may be deleted, so the chapter listed as an appendix, so that is deleted will not affect the text. Predictably, Shanghai jiaotong university press informed me, appendix from chapter dispute see qian xuesen full-text censored. I regret. In the near qian xuesen appeared after, I in seeking truth from facts and unique extricated spirit, spend a lot of time for a careful exploration, in the controversy of qian xuesen, on the basis of strengthening thus, full-text expanded to 7 million words, presented for the qian xuesen brushed gossip .
In check, compared the qian xuesen about the per WanJin food in the original basis, and visited the key parties, finally clarify the WanJin mu case-solving issue-attention, restore the historical truth. Especially investigated 1957, June 16, the China youth daily in qian xuesen nominal issue of the grain area yield how many? Cover-ups, with the facts show that qian xuesen not great leap forward more than horsevaulting, causing starvation 30 million people in the culprit.
As for the human science , in my opinion, that is a dispute between the scientific problems. I described human science historical process, especially the disputes enumerated opposition leader Mr YuGuangYuan doubted 80. Science is always in dispute development. Human science concerned with who, stand-to time concluded.

cannot reach its weight limit

"Engine manufacturing is both must close to the material of the limit, but also . Namely the smaller, thrust the bigger the better, but should grasp this measure is very difficult." Original shenyang engine design institute, said chief designer LiZhiAn ensures that the engine of more than 30,000 a parts in high temperature and high pressure and high speed extreme conditions long-term use repeatedly no any problem, not only for research technical challenge, but also by a national machinery, metallurgy, materials and other industrial foundation level test. At present, the world can self-developed aeroengine only the UN's five permanent members.

Catic industrial KeJiWei original deputy secretary-general PengYouMei is quick to note, over the past years, our country is always "have first plane model, after the engine with aircraft" developed, unaware that 'pre-research first, the importance of dynamic advance ". Compared to the engine, aircraft developed faster time very much, once the wait not to "pay", it will cause the engine cannot batch production, developed a discarded.

"After continuously explore and try, now, our aviation engine development has formed a" producing one generation, developing generation, pre-research generation, exploration of the good development pattern generation "."

2009, June 6, our big planes project assembly manufacturing center was founded in Shanghai, China marked the big planes project design, assembly manufacturing, customer service "three center" layout began to comprehensively promote. LiuDaXiang said the country is expected to use 20 years time, let equipped with the "Chinese heart" "GuoZiHao" big planes to fly on the blue sky.

This year is the China aviation hundred years! Airplane wing of the next century power generation dream, let person "to a" air ideal and faith, struggling to explore, fearless forward. From the youth to the old man, he will become energetic young Chinese heart was beating them economicsystem aviation patriotic responsibility and mission -- to our motherland aircraft powered to Chinese aircraft loaded on "Chinese heart!"
