摘　　要：本文应用Largrange方法,计算了不同倾角的加速斜板作用下的自由面位移。对于垂直板,本文结果精确符合Chwang的结果。In this paber, Lagrangian method is applied to calculate the displacement of the free surface due to the motion of an accelerating rigid sloping plate towards the imcompressible and inviscid fluid which is initially at rest with inclinationθ= 90°?60°?45°and30°?, respectively. The results forθ= 90°?agree accurately with Chwang.s results.
