• In this paper , wavelet analysis is applied in stack at the first time , instead of fourier transform , wavelet transform is applied in frequency division processing of seismic record , no matter in high frequency or low frequency window , the waveform of wavelet function is unchanged , and only change its amplitude and width , the waveform of shorten fourier function is changing in different frequency band
  本文首次把小波分析引入到叠加处理中，用小波变换替代了傅立叶变换对地震记录进行分频处理，由于无论在高频或是低频窗内，小波函数的波形始终不变，只是其包络的幅度和宽度在改变，而窗口傅立叶函数在各频段的波形是变化的。
• Based on the theoretical expression of the average intensity in the fourier transforming and imaging optical system with variable aperture , an algorithm is developed to change the intensity data versus the aperture radius into the bessel - fourier - transform - and - the - inversion of a function of the height - height correlation function . three samples of gaussian correlation are used for the experimental demonstration
  在理论分析和实验测量中，我们采用了变孔径的傅立叶变换和成像系统，由所得到的像面光强的解析式，建立了将平均光强随孔径的数值变化关系转化为正逆傅立叶变换对，从而恢复出表面的高度?高度相关函数。
