摘要
该文讨论了间接测得量是直接测得量的一元函数及多元函数时,间接测得量平均值计算方法。按传统的做法是先求直接测得量的平均值,代入它们的函数关系,便得到间接测量量的平均值。文中从理论上分析了这种传统做法的不合理,并提供了合理的方法。同时指出了该文所提供的方法与传统方法之间的误差,及两种方法的等价条件。
The method of average calculation of the indirect measurement,whichmay be a function of a single variable or of many variables to the direct measurement,has been discussed.According to tradition,the average va-lue of direct measurement is substituted to the relasion of function.Theaverage value of indirect measurement then achieve.This unreasonablemethod is analysed theoretically.Meanwhile the reasonable method andthe error between the new method and the traditional one as well astheir equivalent condition has been provided.
