摘　　要：伯努利方程是能量方程,推导过程有多种途径,本文从动力学角度根据功能原理推导伯努利方程,只研究理想流体在作定常流动时伯努利方程的推导过程,并讨论在不同条件下方程中各项的物理意义,最后讨论p/ρ项的物理意义.Bernoulli equation is an energy equation; there is many ways of deduced process. This article deduced Bernoulli equation according to the principle of work and power in terms of dynamics. We are not only research the deduced process of Bernoulli equation when frictionless fluid is doing steady flow also discuss the physical significance of each item under different terms. In the end, we discuss the physical significance of p/ρ items.

关 键 词：动力学 功能原理 伯努利方程
