摘要
本文将随机变量的特片函数运用到量子力学中去,以求解力学量的平均值和测不准关系。并指出当力学量的几率密度函数是正态分布时,求解过程变得更加简单。
In this paper, we apply the characteristic function of randon varlable to quantum mechanlcs in order to calculate cxpectation value of mochanical quantities and uncertainty relation. We will also point out that when the characteristic funtion of mechanical quanties are in normal distribution, the process of calculation is even easier,
