分析论述了我国在测报近震震级和面波震级业务中存在的种种问题，用现行起算函数测算的ML随震中距存在系统偏差，近场偏低，远场偏高；此函数系统建立的方法有不合理之处，它不适于DD-1仪。用现行公式测算的MS与国际上震级水平不一致，总体趋势偏高；在90(距离上震级零点严重失控；用单一水平向记录计算MS是个原则性差误。需要用新的起算函数系统代替R1(()计算ML; 需要用新的公式取代现行公式计算MS。
Analyzed and discussed the problems existing in the near-epicenter magnitude and surface-pollination magnitude of our country, the systematic deviation of ML with epicentral distance measured by the current initial computing function, the low near-field and the high far-field; the method established by this function system There are unreasonable, it is not suitable DD-1 instrument. MS calculated from the current formula is inconsistent with the international magnitude level, and the overall trend is high; at 90 (a serious loss of control from the zero point of the upper magnitude magnitude; MS calculation using a single horizontal record is a principle error.) A new starting function system needs to be used instead of R1 () To calculate ML; need to replace the existing formula with a new formula to calculate MS.
