摘要
提出简谐振动“方根能量”矢量图的概念（以下简称“根能量”矢量），指出了根能量矢量图和振幅矢量图的关系．利用根能量矢量图可以直观方便的分析或求出谐振动中的能量问题．
This article states the principle of simple harmonic vibration energy diagram. It points out the relationship between energy vector diagram and amplitude vector diagram. By applying energy vector diagram, we can analyze and solve the energy problem of vibration.
