摘要
将同一台址同一地震不同观测系统所测的数字震级与模拟震级进行统计,作回归分析,计算两者之间的相关值,比较它们的差异性。结果表明,模拟震级与数字震级相关程度较好,数字震级完全可以替代模拟震级。
the difference between the magnitude of earthquakes given by digital and analogue observation in one station is compared by statistices and regression analysis.The results show that the relativity in digital and analogue magnitudes is good,and analogue magnitude can be replaced by digital magnitude.
