研究地震检波器阻尼随温度变化的规律,测量了不同温度下地震检波器阻尼(系数),通过有关数据分析揭示了地震检波器阻尼随温度变化的规律,给出了典型的响应曲线。探讨了影响阻尼变化即控制其温度响应的主要因素。最后,提出了通过材料温度系数优选组合或采用适当温度补偿系数调整电阻以实现其阻尼温度响应平稳性的对策,并给出了初步实验结果。

The law of geophones' damping variation with temperature is researched. Damping of geophones in various temperatures is tested, the relative laws are revealed through data analyzing, and some typical response curves are given. Then, the factors which affect damping variable,namely control its temperature response are discussed. Finally, together with the prime experimental result, strategies for achieving flat damping-temperature response are proposed through material optimization arrangement or regulation resistance with temperature compensation coefficient.
