Engineering thermal physicist. Born in Shanghai. Graduated from Southwest Associated University. Received Ph.D. from MIT,USA in 1947. Research professor, director and honorary director,Institute of Engineering Thermalphysics, Chinese Academy of Sciences.

In the early 1950s, Wu published his theme “ Universal Theory of Three-Element Flow in Axial-,Radial- and Mixed-flow Subsonic and Supersonic Blade Turbine Macninery” which was designated as “Wu’s universal theory ”, and the main equation of which was designated as “Wu equation ”. In the 1960sm he presented the basic equations using arbitrary non-norma speed components of the three-element flow in the blade turbine machinery. “Wu’s universal theory” has been widely used in the design of advanced aeronautical engines internationally. Under his leadership, a complete set of sub-, trans- and super- sonic speed computer methods and computer programs were developed and widely used. He made significant contributions to the improvement of utilization of China’s energy resources.

He became Member of the Chinese Academy of Sciences in 1957.

鐵路橋梁工程專家。上海市人。早年唐山交通大學畢業(yè)后，報送去美國康奈爾大學學習，獲碩士學位。鐵道部副部長、總工程師、研究員。在負責修復被嚴重破壞的錢塘江大橋工作中，應用了結(jié)構(gòu)力學原理，采用套箱加固基礎，用少數(shù)排架頂換修補鋼梁等方法，使被嚴重破壞和變形的鋼梁恢復原狀，保證了修復質(zhì)量。1958年，在參加指揮搶修被洪水沖毀的黃河鐵路大橋時，改變臨時結(jié)構(gòu)，確定搶修方案，為大橋提前修復通車做出了貢獻。在主持武漢長江大橋全面技術(shù)工作時，同蘇聯(lián)專家在解決重大問題時密切合作，使大橋勝利提前建成。在主持新線鐵路建設工作中，大力提倡機械化和小型機械化相結(jié)合的施工方法，做出了顯著成就。

1957年被選聘為中國科學院院士（學部委員）。

Railway bridge engineering expert. Born in Shanghai.Graduated from Tangshan Jiaotong University. Received MS from Cornell University USA. Vice Minister, chief engineer and research professor, Ministry of Railways.

When taking charge of the reconstruction of the seriously damaged Qiantang River Bridge, Wang applied the principles of structural mechanics to consolidate the foundations with jacketed box and replaced steel beams with frame bents, made the deformed steel beams resumed to their original states and ensured the quality of the repayment. He led the rush repair work of the Yellow River Railway Bridge burst by flood in 1958 and made possible the open of traffic ahead of schedule. He also cooperated closely with the Soviet experts in solving major problems when directing the overall technical work of Wuhan Yangtze River Bridge construction and made the Bridge construction a success.

He became Member of the Chinese Academy of Sciences in 1957.

王元

1930.04.30～

數(shù)學家。原籍江蘇鎮(zhèn)江，生于浙江蘭溪。1952年畢業(yè)于浙江大學。中國科學院數(shù)學研究所研究員。主要從事解析數(shù)論研究。50年代至60年代初，首先在中國將篩法用于哥德巴赫猜想研究，并證明了命題{3,4}，1957年又證明了{2,3}，這是中國學者首次在此研究領域躍居世界領先地位，其成果為國內(nèi)外有關(guān)文獻頻繁引用。與華羅庚合作，于1973年證明了用分圓域的獨立單位系構(gòu)造高維單位立方體的一致分布點貫的一般定理，被國際學術(shù)界成為“華—王方法”。70年代后期對數(shù)論在近似分析中的應用做了系統(tǒng)總結(jié)，產(chǎn)生了廣泛的國際影響。80年代在堆壘數(shù)論方面，將施密特定理推廣到任何代數(shù)數(shù)域，即在丟潘圖不等式組等方面做出先進的工作。

1980年當選為中國科學院院士（學部委員）。

In the 1950s and early 1960s, Wang employed for the first time in China the sieve method in the study of the Goldbach Conjecture and proved the proposition {3,4}, and later proved the proposition了{2,3}, in 1957. These results showed that Chinese scholars for the first time leapt to the world leading position in this field and were frequently quoted in corresponding literature both at home and abroad. Collaborated with Professor Hua Luogeng,he proved a general theorem on uniform distribution of highdimensional unit cube constructed with the independent set of units in cyclotomic field, which was acknowledged as “Hua- Wang Method” by the international academic circles. In the late 1970sm he systematically reviewed the application of number theory to approximate analysis and won international respect. In the 1980s,he succeeded in the generalization of the Schmidt Theorem on Diophantine inequalities of many variables to arbitrary algebraic number field.

He was elected Member of the Chinese Academy of Sciences in 1980.
