摘　　要：本文明确提出了合金元素铜当量J的存在.指出合金元素的锌当量系数与铜当量系数之间的并存,互补的一元关系,给出了K、J的初步定义式。通过K+J=1的推导,进一步证明了合金中当量含锌量的增加量即等于其中相对应的铜量减少(即K+J=0)这一近似性提法的错误。Synopsis: Relying on an objective intuition to the physical seuse of the formula. i. e. mathematical expcession. along with the consideration upon the translation of zinc equivalent in alloying elenent at three levels, the writer discovers and verifies some problems in the current calculating formula by chance. and further advances tentalively three plain calcldating formulas. It points out that the problems are caused objectively by the fact shich“Equivalent Total Weight”is not exsted. however the wrong conception and conclusion of“Equivalent Total Weight”is retained in that formula.
