摘要
基于代数法建立了溶液中同种物质不同型体分布分数四则运算的新方法。该方法仅需对pL及相关lgK进行少量加、减及以10为底的乘方运算。该方法简便、快速,计算结果的相对误差可预先设置,一般不超过5％。
A new method for the four fundamental operations of arithmetic for the distribution coefficient was set up on the basis of algebraic method. The calculation can be carried out by only using addition, subtraction and simple exponent of relative pL and lgK, it is simple, convenient and rapid. The relative error may be predesigned, the relative error being≤5%
