摘　　要：根据数学理论对光栅谐振子检测地震波系统进行了定义,光栅谐振子检测地震波系统的输入、输出信号均为一维的连续时间函数;建立了数学模型和物理模型;对光栅谐振子检测地震波系统的阻尼进行了分析,计算了铝筒整体受力情况,提出了适当增加阻尼的改进措施.Based on the research work and considering the actual environment in which the system is in application, the seismic wave detecting system by grating geophone was defined. Both the input and the output signal of seismic wave detecting system by grating geophone are continuous time functions.Then the mathematic and physics models were presented. Also, the damp of the system was analyzed and some improvement measures were proposed in this paper.
