本文探讨了地震观测系统影响资料分辨率的相关效应和平均效应。首先．分析了观测系统影响地震分辨率的机理,指出相关效应和平均效应的综合将导致地震分辨率的降低。然后,定义总相关效应和最大离散距,并用这两个参数来表征观测系统的负效应。最后,给出高分辨率地震观测系统的量化标准,及减少观测系统负效应的一系列对策。

This paper makes a study of correlation effect and average effect of seismic layout on data res-olution. Firstly,we analyze the mechanism about effects of layout on data resolution,and point outthat the combination of the two kinds of effects will result in lowering of resolution. Then,totalcorrelation effect and the biggest discrete distance are defined,and they are used to characterize thenegative effect of seismic layout system. Finally,quantizing standard for high resolution layout anda series of countermeasures depressing the negative effect of layout are showed.
