摘　　要：精确测量动圈式地震检波器灵敏度对获取高质量的地震勘探资料是十分重要的 ,而用直流激励法测量动圈式检波器灵敏度与实际结果出现差异。文章在论述测量原理的基础上 ,指出了该方法在测量过程中忽略了检波器实际响应中的放电尖脉冲对灵敏度测试结果的影响 ,从而揭示了直流激励法灵敏度测得值要小于经典振动法的原因。It is stated in this paper that principle of measuring sensitivity for coil geophones with direct current exciting method. The sensitivity value measured with above method is smaller than that with the classic vibration method. The reason is that the direct current exciting method does not consider the effect of discharging impulse to the measured value. Some attempts are made by the author for the traceability of the sensitivity value measured with the direct current exciting method and at last a feasible scheme is given for eliminating the measuring error coused by the above method.
