| 摘 要： | 以线性系统频谱分析方法为理论依据，将受天然和人工两方面因素控制而呈非平急状态的地下水动态序列，化为平稳序列。根据对含水系统输入和输出的谱分析，确定系统的频谱响应函数，利用逆傅里叶变换，给出系统的脉冲响应函数，从而建立地下水动态随机预模型。

| Abstract: | According to the spectral analysis method of linear system, this paper converts the groundwater regime of nonstationary process, which is controlled by both factors of nature and man, into stationary precess. The frequency-spectrum response function is derived from the spectra of the input and output of the system, and then is turned into the pulse response function by operating inverse Fourier Transform. UP to now, the stochastic prediction model can be obtained. |
