用螺旋矢量分析阻尼振动

An Analysis of the Damped Vibration by the Spilal Vector

本文用螺旋矢量分析了阻尼振动，得到了阻尼振动的振幅与位相之间相关联的明晰图象，并指出了两个常见的错误。

In this paper, we analyse damped vibration by the spiral vector andabtain a clear pre+Sentation of the relationship between the amplitude and thephase.Moreover, we point out two errors existing in' some book.
