摘要
介绍了流体动力学三大方程中伯努利方程的基本理论,介绍了一些可以用此方程解释的生活中常见的现象,以及此方程在工程技术科学方面的应用,如用压力装置从大油桶中压取食用油的原理、火车"吸"人的原理和飞机能浮起的原理等。
The thesis focuses on Bernoulli equation-the great equation of fluid hydrodynamics three fundamental theory equation. It mentions some phenomena in our daily life that can be explained with this equation, and the application of this equation in engineering technology. For example, pressure is exerted to get edibie oil from huge oil drums;trains ＂takes in＂ people and airplanes float.
