均值为零的正态随机变量研究

Research on the Normal Random Variable ofit's Mathematical Expectation Being Zero

在正态随机变量乘积矩基础上，给出了正态随机过程平方后的协方差函数的计算，这一结果在实际上有着重要的应用价值．

On the basis of the product moment of the normal random variable, the paper gives how to calculate the covariance function, which is normal stochastic process square. The result of the calculation has important value in the application.
