摘要
本文通过各地量规函数的分析研究,认为量规函数主要反映地震波区域衰减特征,不宜将-量规函数任意推广,要以地质构造分区,建立区域性量规函数。台站校正值在区域量规函数适合的基础上考虑,不能以台站校正值代替量规函数的修订。根据100多个台站资料的综合研究,不同岩性的台基,台站校正值都不大,一般在-0.3<S<0.3之间。
By analysing the different regional calibration functions, it is found that the calibration functions show mainly the local attenuatiou coefficient of seismic waves and do not extend to any research field of seismic activity. According to geological construction unites, the local calibration functions are set. The calibration functions should be considered first, before correc-ting station values, the correction values of station cannot replace function correction. Based on the comprehensive research of over 100 seismic station data the functron value varations for different site condition station are not obvious, generally, they are about ±0.3.
