摘　　要：有关钻孔应变仪的地震监控范围问题,人们的认识有较大差异。为了准确地说明这一问题,本文从应变仪检测能力的时间特性入手,并总结了应变前兆分布的时间—空间规律,其中包括了我国体应变仪的资料,由此得出了长中期、短期和临震前兆的监控范围。这些结果对于应变仪台网布设方案的制订,对于前兆资料分析认识的深化具有参考价值。对一些参数稍作变动后本文的计算结果也可应用于倾斜仪和伸缩仪等前兆仪器。There exists relatively large difference in understanding the earthquake-monitoring extent of borehole strainmeter. In order to explain this problem exactly, this paper starts with the time characteristics of the monitoring capability of the strainmeter and summerizes the time-space regulations of the strain precursory distribution, among which included the data of volumetric strainmeter from our country, and therefore obtained the monitoring and controlling extent of long-and medium-term, short-term and impending precursors. These results are of reference value for working out the layout plan of strainmeter network and deepening the analysis and understanding of precursory data. By means of making slight change of some parameters, the computed results of this paper can also be applied to the precursory gauges, such as tiltmeter and tensometer.
