1·It was devoted to the relative damping measurement for overdamped geophone with a moving coil of constant velocity.
对动圈式恒速度型过阻尼地震检波器相对阻尼系数的测量方法进行了研究。
2·The geophone's parameters was estimated in this paper through LSM (least square method) combined with theory and experiment modeled in two steps.
采用最小二乘法结合理论-实验二次建模对地震检波器的参数进行了估计。
