| 摘 要： | 本文讨论了（１）检波器的自然频率、寄生频率和平静工作带宽的关系；（２）寄生频率与记录系统中防假频滤波器的关系；（３）在野外实验中由寄生频率引起的谐振动对地震记录的影响；（４）检波器的灵敏度、输出电阻与记录系统输入阻抗的关系；（５）检波器相一频特性的重要性等这些不应被忽视的问题。说明了检波器的性能在精确勘探中的重要性。

| Abstract: | This paper discusses: (1) the relation of geophone na tural frequency, s purious frequency with quiet working bandwidth, (2) the relation between spuriou s frequency and anti-alias filter in recording system, (3) the influence of res o nance on seismic data due to spurious frequency in field tests, (4) the relation of geophone sensitivity, output resistance with input impedance of recording sy stem, and (5) the importance of geophone phase-frequency characteristic. It is pointed out that the geophone property is important in precise seismic explorati on. |
