伯努利定理的意思、翻譯和例句

是什麼意思

「伯努利定理」是流體力學中的一個基本定理,描述了在一個不可壓縮流體流動中,流體的壓力、速度和高度之間的關係。根據這個定理,流體在流動過程中,當流速增加時,流體的壓力會減小;反之,當流速減少時,流體的壓力會增加。這一原理被廣泛應用於航空、工程和其他科學領域,例如解釋飛機的升力、噴水器的工作原理等。

1:Bernoulli's principle

用法:

這一原則是由瑞士數學家丹尼爾·伯努利於18世紀提出的,主要用於流體力學中,解釋流體動力學的基本行為。它表明在一個流動的流體中,流速越快的地方,壓力就越低。這一原則對於設計飛機、氣流及水流系統等工程應用非常重要。
