柏努利方程的准确理解及应用

Correctly Understand and Use Bernoulli's Equation in Teaching

针对学生课堂学习过程中普遍存在的对柏努利(Bernoulli)方程理解和应用上的困难,阐述了准确理解柏努利(Bernoulli)方程的几个关键点,比较了柏努利方程与机械能守恒方程的主要区别,讨论了正确掌握柏努利方程应用及有关计算的技巧和方法。

This paper described the several key points to correctly understand Bernoulli＇s Equation based on the difficulty which students widely come across in their learning. Main difference between Bernouili＇s Equation and conservation law of mechanical energy was compared. The skills and methods which to correctly use Bernoulli＇s Equation in the related calculation were discussed.
