一、十字交叉法的比值含义十字交叉法通常用于二元混合体系,是进行二组分混合物组分比例大小计算的一种简便方法,该法在计算过程中的关键是求出均值。它的数学表达式:a_1是单组分1的一个量,a_2是单组分2的一个量,a是单组分1与2的一个平均量。在应用中值得注意的是a_1、a_2、a均为比值关系且物理意义完全相同,这样才能保证进行做差运算和确定比值的含义。十字交叉法的差值比的物理含义与均值分母项具有很大的相关性,差值比的物理含义与均值分母
First, the cross-law ratio of the meaning of meaning Cross-cross method is usually used in the binary system is a mixture of two components of the proportion of a simple method of calculating the size of the method in the calculation of the key is to find the mean. Its mathematical expression: a_1 is an amount of one component 1, a_2 is an amount of one component 2, and a is an average amount of one component 1 and 2. It is noteworthy in the application that a_1, a_2, a are the ratio of the relationship and the exact same physical meaning, so as to ensure that the difference between doing arithmetic and determine the meaning of the ratio. The cross-difference method has a great correlation between the physical meanings and the mean denominator terms, the physical meaning of the difference ratio and the mean denominator
