中英雙語話中國歷史名人 第84期:李四光

Li Siguang (1889~1971), is the founder of China's geomechanics. A native of Huanggang, Hubei, Li studied in Japan and the United States in his early years.

李四光(1889~1971)，中國地質力學的創建人，湖北黃岡人。早年曾在日本、美國留學。

He became a geological professor at Peking University upon his return from abroad in 1920.

1920年回國到北京大學任地質學教授。

After the People's Republic of China was established, Li held the positions of deputy president of the Chinese Academy of Sciences and minister of geology.

中華人民共和國成立後，李四光任中國科學院副院長、地質部部長。

In the 1920s, Li Siguang set up the subject of geological mechanics and made great contribution to the geological theory.

1920年，李四光創立了地質力學，爲地質理論作出了巨大貢獻。

He studied lithosphere with the mechanic theory, and established the tectonic system, one of the basic concepts of tectonic mechanics. He provided new ways to explore the natural phenomena and ushered in new ways of studying the lithosphere movement.

李四光運用力學觀點來研究地殼運動現象，建立了“構造體系”這一地質力學的基本概念，爲探索地質自然現象提供了新方法，爲研究地殼運動規律開闢了新途徑。

His theory made great contribution to China's oil reconnaissance and survey, changing the situation of “oil-deficiency" in the country, enabling the large-scale development of oil fields to raise the country to the ranks of the world major oil producers.

他的理論爲中國石油勘探作出巨大貢獻，改變中國的“缺油”局面，使得大規模的油田發展將中國變成了世界主要的石油生產國。

With the geological mechanics, he analyzed the geology and pointed out that China had abundant oil and gas resources.

李四光運用地質力學分析了中國地質構造特點，認爲中國具有廣闊的找油遠景。

The continuous development of Daqing oilfield, Shengli oilfield and Dagang oilfield proved that Li Siguang was really far-sighted in science.

大慶、勝利、大港等油田的相繼發現證實了李四光的科學預見。

In the earthquake studies, Li Siguang emphasized the importance of observing changes in terrestrial stress on the base of studying geological structural movement, and showed clearly the orientation for earthquake forecasting work.

在地震地質工作方面，李四光強調在研究地質構造活動性的基礎上，觀察地應力的變化，爲實現地震預報指出了方向。

What's more, as early as the 1920s, Li Siguang visited many places such as the piedmont of Taihang Mountain, Datong Basin, Lushan Mountain and Huangshan Mountain, and found the vestige variations of the Quaternary Period glacier.

此外，李四光早在20年代初，實地考察了太行山麓、大同盆地、廬山和黃山等地，先後發現第四紀冰川遺蹟。

He proved wrong many academic authorities' conclusion that China had no Quaternary Period glacier.

推翻了國際上許多冰川學權威斷言中國無第四紀冰川的錯誤結論。
