This paper also show a rough estimate of the gains of this array, because it needs one year's data to collect one year's noise correlation variation curves and then give a more practical detection ability of the seismic array . one result of this paper is " seismic array site survery data processing software " exploited by the author . the software can calculate the power spectrum of noise for every site, noise coherence function for every site pair, the cross-correlation curves, the root mean square of noise for every site and the array response 此外还计算了该台阵的台阵响应,发现台阵响应的主瓣高而尖;旁瓣很小,这歪姐钮远宣腔挝踏数公镀壁韶逼上拢唆精确啻应:有关此台阵的检测能力,只能给出一个粗略的估计,因为评价一个台阵对地震事件的检测能力需要获得为期一年的观测资料,才能给出一年内噪声场变化的相关值曲线,最终给出更加符合实际的台阵检测能力。
