考虑稳定线性动态系统对白噪声输入的平稳输出。结果表明，输出的谱矩可以确定为一组线性方程的解。相应的解决方案用于确定不恰当的积分，这在线性动态系统的随机振动分析中非常有用。
The stationary output of a stable linear dynamic system to white noise input is considered. It is shown that the spectral moments of the output can be determined as the solution of a set of linear equations. The corresponding solutions are utilized for determining an improper integral which can be quite useful in random vibration analyses of linear dynamic systems.
