| Abstract: | 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, |
