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 discusses the correlation effects and the average effects of seismic observation system on data resolution. First of all. The mechanism of observing system affecting seismic resolution is analyzed. It is pointed out that the combination of correlation effect and average effect will lead to the decrease of seismic resolution. Then, define the total correlation effect and the maximum discrete distance, and use these two parameters to characterize the negative effects of the observed system. Finally, the quantitative criteria of high resolution seismic observation system and a series of countermeasures to reduce the negative effect of observation system are given.
