摘　　要：提出在空气中运动的复摆,受到与速度和速度平方相关的复合阻力作用,得出在复合阻力影响下复摆运动的微分方程,利用平均法求出小角振动条件下该方程的近似解析解,并与数值解结果进行了比较.The differential equation of a compound pendulum motion effected by composite resistance which relative to the speed and the square of the speed has been given.The approximate analytic solution of that equation has been obtained by averaging method.And the approximate analytic result was compared with the numerical result.

关 键 词：线性阻力 平方阻力 复摆 平均法
