| 摘 要： | 在深入分析研究了速度传感反馈地震计传统设计方案的基础上，提出了技术性能更优的传递函数两步实现方案。两步方案为反馈环路设计带来的巨大灵活性，又促使我们跳出传统的“延长周期”模式的思路束缚，提出了单纯阻尼反馈环的设计新思路。理论计算表明，两步方案与阻尼环结合的设计可以使速度传感反馈地震计的技术性能达到更高境界。反馈深度大、环路稳定性好，动态范围大和极点稳性高使它明显优于传统设计方案。

| Abstract: | We analyze the traditional design plot of the speed sensor of seismometer and put forward a new method of two steps implement of transmit function and a feedback circuit of a pure damp. The method is more advanced and more convenient for the feedback circuit designing, in which we do not adopt the thought using traditional mode of prolonging cycle. The theory calculation shows that the design of combining the new method of two steps implement with the feedback circuit of a pure damp can make the speed sensor of seismometer more reliable, stable and deeper feedback compared with the traditional method. |
