组合型式是组合理论的应用,它们在空间上可过滤规则噪音。震源和检波器单元,地震记录的道,共深度点道集的排列都可构成组合型式。组合型式的富氏变换产生组合或滤波响应曲线。当干扰与讯号占据同一频带,但由于干扰与讯号两者的波长不一样,就可设计一种组合装置接受讯号和衰减干扰. 根据组合理论导出的结果,理应成立,但在实际上却不一定能用,这是由于设计的装置不充分和导出的结论不正确所致,理论是成立的,但在应用中却必须予以改进。
Combination patterns are the application of combinatorial theory that spatially filters regular noise. The combination of source and geophone units, seismograms and common depth point gathers can all be combined. Combined versions of the Fourier transform result in a combined or filtered response curve. When the interference and the signal occupy the same frequency band, since the wavelengths of the interference and the signal are not the same, a combination device can be designed to receive the signal and attenuate the interference. According to the results derived from the combinatorial theory, it should be true but not actually Can be used, this is due to inadequate design of the device and derived conclusions are not correct, the theory is established, but it must be improved in the application.
