震级M_L、M_S、M_(LH)与能级K的定量关系

The quantitative relation between magnitude M L, M S, M LH and energy level K

在修定１９７０～１９９０年中国吉尔吉斯斯坦、哈萨克斯坦三国边邻地区地震目录编辑２５０～１９９０年天山地震目录的工作过程中，为解决不同震级标度间的转换问题，在统计分析计算的基础上得到了Ｋ＜１２０能级范围内Ｋ与ＭＬ、Ｋ≥１２０能级范围内Ｋ与ＭＳ的换算关系表达式。

In this paper, in order to treat the problem of different magnitude scales, the transform formulas for K and M L( K <12.0) or K and M S( K ≥12.0) have been obtainded and the tables of transform values also have been given on the basis of data analysis. These data include revised seismic catalg (1970～1990) in three countries′ boundary region (China, kirghizia and Kazakhstan) and edited seismic catalg(250～1990) in Tianshan area by us.
