【摘要】 研究温度对动圈式地震检波器的参数的影响.在对精密测量的地震检波器的参数进行数据分析的基础上,揭示了地震检波器输出电阻、自然频率、阻尼和灵敏度等4个参数的温度响应,分析讨论了有关参数对温度的变化规律.提出了控制这种变化的对策,初步实验结果证实了其可行性.最后,指出地震检波器参数的变化是可控的,同时认为如无原理上的重大改进,高精度的超级检波器最可能实现在10-20Hz频率范围中.更多还原

【Abstract】 The temperature influence on parameters of a geophone is studied. Based on data analysis for the parameters measured in high precision, their responses to temperature are revealed, including the output resistance, natural frequency, damping and sensitivity. Some strategies are proposed for controlling the variations with respect to temperature and the feasibility is shown by the preliminary experiment results. At last, it is shown that the parameters of a geophone can be controlled, and without a further significant improvement, a supper-geophone with high precision can be made working in a range of 10-20Hz.更多还原
