一、引言自1935年里克特首次发表震级公式以来[1],关于震级标度的改进、发展的研究已经经历了将近半个世纪。怎样使得震级标度能符合计量学的“实用、合理、精确”三项要求,这是一个值得认真探讨的问题。当前存在有多种震级标度,对同一地震所测定的结果彼此相差 I. INTRODUCTION Since Richter first published the magnitude equation in 1935 [1], the research on the improvement and development of the magnitude scale has undergone nearly half a century. How to make the scale of magnitude meet the three requirements of “practicality, reasonableness and precision” of metrology is a question worth serious study. Currently, there are many scale scales, which are different from each other for the same earthquake
