实验设计与误差分配

误差分析主要有二类，一类是误差综合，另一类是误差分配，实验设计是以给定的测量结果的误差来确定在此测量中所用的标准，相关设备的误差值及参比条件允许偏差程度，因此 在本质上实验设计过程是误差分配的过程，作依据微小误差准则探讨如何实现合理的误差分配，并以电能表检验装置作为实例予以说明。

The design of experiment and error distribution

There are two matters in error analysis,the one is error synthesis,the other is error distribution.The design of experiment in essence is equal to the process in which the errors of the standard,the relative devices and the permitted deviation are defined according to the given error of experiment,this process is called error distribution.Thus the design of experiment and the error distribution are linked together.The authors probe into how reasonably realizing the error distribution by using micro-error principle,and describe the process with an example of the testing equipment for Watt-hour meters.
