摘　　要：简要介绍了全光纤加速度地震检波器的工作原理和敏感元件的结构特征 ,详细描述了质量块横向振动限制膜片的设计理论。实验结果表明The operation principle of all fiber optic acceleration seismometer and structural characteristics of transducing element are introduced briefly The design considerations and theory of the diaphragms constraining transverse vibration of the transducing mass are described in detail The final experimental results indicated that the frequency spectra of the seismometer employing the diaphragms is improved obviously as compared to that of the seismometer without any constraining
