| Abstract: | There is no unimous and complete method of spectral analysis for unsteady stochastic process so far. Many problems about the frequency domain characteristics of the unsteady stochastic process should be further recognized and diseuased. In this paper, its meaning and characteristics under several definitions are systematically discussed. |
