摘　　要：选取我国强震动观测台网使用较为广泛的7种强震动记录器,在实验室中模拟极限工作环境温度,选取5个温度测试点,通过测量仪器自噪声,分析计算各温度点仪器零位漂移值。通过计算得出在极限温度下,GDQJ2型仪器零位漂移值较大,BASALT型与EADS型仪器零位漂移值较小,但7种实验仪器的技术指标均满足地震行业规范要求。本实验也为将来在真实环境下的强震仪零位漂移温度实验提供参考。This article discusses 7 kinds of the most widely utilized strong-motion recorders that have been employed by the National Strong-motion Monitoring Platform. In a dummy work envi- ronment with 5 testing points from the highest to the lowest temperature, through detecting the instinct-noise of the strong-motion recorders, the values of zero drift of the recorders in different testing points were analyzed. Our conclusion is that the zero drift of GDQJ2 is the highest, and the values of BASALT and EADS are relatively lower. All the 7 kinds of strong-motion recorders comply with the industry standards. This experiment can also be a reference of detecting the zero drift of the recorders in the real work environment.
