| 摘 要： | 洪水波在运动中不变形，则没有内摩阻损失，即所谓运动波。波体在传统途中变形，则有加速项或惯性力，内摩阻力等于惯性力。动量没有内摩阻损失，能量有内耗，故在非平稳流情况下，动量方程要比能量方程多一项惯性波。

| Abstract: | If the flood wave was not deformed in motion,there was no internal friction loss,which is called kinematic wave. If the flood wave is deformed on its way of propagation ,there exists acceleration term or inertia force that equals to internal friction.Momentum is not effected by internal friction,but which exists in energy.therefore,momentum equation has more a term of inertia gradiant than energy equation in unsteady flow. |
