| 摘 要： | 当前,经仪器响应失真校正后,加速度计有效观测频带通常为0至1倍自振频率,这限制了强震仪应用领域的延拓。有鉴于此,本文提出一个基于精确权函数的仪器响应失真校正方法并给出一个验证算例。分析表明:较之现有方法,新方法兼有高精度和高效率的优点,并可以将力平衡式加速度计的有效观测频带至少延拓3倍,对于拓展强震仪的应用领域具有重要意义。

| Abstract: | So far,after instrument correction,the observation frequency band of force-balance accelerometer is about from 0 to one time of natural frequency,which is a limitation to extensive application of strong motion seismograph.Based on an exact weight function,this paper puts forward a new kind of method for correction to instrument's response distortion and gives a calculated example for verification.As compared to existing methods,the new method is not only with high precision,but also with high efficiency.It can extend the effective observation frequency band of force-balance accelerometer at least 3 times,which has real meaning in application field for extension of strong motion seismograph. |
