1引言瑞士数学家丹尼尔·伯努利在1726年首先提出“伯努利原理”.这是在流体力学的连续介质理论方程建立之前,水力学所采用的基本原理,其本质上是流体的机械能守恒.对流体力学学科的形成作出第一个贡献的是古希腊的阿基米德,他建立了包括物体浮力定律和浮体稳定性在内的液体平衡 1 Introduction The Swiss mathematician Daniel Bernoulli first proposed the Bernoulli Principles in 1726. This is the basic principle used in hydraulics before the establishment of the theoretical equation for the continuous medium of fluid mechanics. It is essentially a fluid. The conservation of mechanical energy. The first contribution to the formation of the discipline of fluid mechanics was Archimedes of ancient Greece. He established liquid balances including the laws of buoyancy of objects and the stability of floating bodies.
