在能量表象中用密度矩阵处理线性谐振子

Treat of Linear Harmonic Oscillator By Means of Density Matrix In Energy Image

这里主要讨论在能量表象中利用密度矩阵处理线性谐振子问题，然后再将其变换到坐标表象和动量表象中讨论其分布函数。它具有计算简便。

Treat of linear harmonic oscillator in energy image by means of deusity matrix is discussed.It is then transformed to coordinate image and momentum image,and its distribution function is studied.It is of the characteristic of easily colculaling and a clear physical concept.
