摘要
本文从功能原理出发，用旋转矢量法推导了稳定受迫振动中的振幅和初相公式，讨论了当ω＜ω、ω＞ω。和ω＝ω＿０３种情况下其功能转换关系．
n accordance with the generalizde work-energy theorem, the expression of amplitude and initialphase in stable forced oscillation is obtained by rotating vector method. The transformation ofwork and energy is discussed in three cases of ω<ω, ω>ω, and ω=ω.
