課程介紹:
在本系列課程中,圣母院大學提出了“你會為什么而奮斗”這一話題,主要圍繞學生們和教職人員的研究、學術(shù)成就和社會行動力展開。本片采取紀錄片形式,采訪了很多不同的人。
學院介紹:
圣母大學(University of Notre Dame)創(chuàng)建于1842年,位于美國印第安那州的南灣市,是一所文理兼顧的著名私立大學。大學校風嚴謹、純正,學生非常熱衷于各項志愿的社會工作,也有大量學生加入社會事務中心,幫助照顧老人及傷殘人員。

My name is Julia Stevens. I'm 25 years old. I'm a third year graduate student going for my Ph.D. at Notre Dame. The price of fuel since I started driving has gone from less than $1 a gallon to $3.5 a gallon. Everybody's feeling it and the airline industry is feeling it as well.
You go to the airport and you realize the number of aircraft that are there and the amount of fuel they use become conscious of the impact -- this has on our consumable resources and fuel usage in this country and in the world.
Julia's research involves making turbines in jet engines run more efficiently. A small improvement in the efficiency of the turbine has a significant improvement of the overall efficiency of the jet engine.

我是茱莉亞 史蒂芬,25歲,現(xiàn)在研三準備讀博。從我開車開始,燃油價格就從不到1美元一加侖漲到3.5美元一加侖。大家都能感覺到,航空業(yè)也是。 當你去飛機場,你就會知道那里有多少航班,意識到飛機的巨大耗油量會造成怎樣的影響,這些影響會反應在我國甚至世界的資源使用上。 茱莉亞的科研包括如何使噴氣發(fā)動機中的渦輪效率更高。渦輪效率的小小提高,就能很大程度地提升發(fā)動機的使用效率。
