【摘要】 本文提出了氧化还原总反应中计算物质当量因子(d_x)的通用规则,此因子(d_x)值等于由两个氧化还原半反应相减而得到的总反应中物质的分子式前的系数同被约去的电子数的比值。并通过列举的例子说明其应用的普遍性外,还具有既方便又简明的特点。更多还原

【Abstract】 An universal rule used for calculating the equivalent factor of substances in a general redox-reaction(dx)is Suggested in this paper.The value of the factor equals the ratio of the coefficient of a molecular formula of a substance,which is resulted in the general reaction from substraction of two semi-redox-reaction,to the reduced electron numbers. With the examples in this article we find besides its popularity,the uni- versal rule has the features of convenient and succinct.更多还原
