动态测量中最佳方案的选择

DETERMINATION OF THE OPTIMAL PROCEDURE DURING DYNAMIC MEASURING

在动态测量中，当测量结果与各误差因素之间难于找到某种特定的函数关系时，用统计学理论提供的最佳测量方案选择方法很难进行处理。为解决这一问题，本文以灰色系统理论为基础，提出了动态测量中一种新的最佳测量方案选择法，它特别适用于不易寻求各误差间确定关系的复杂测量系统。

It is very important to make choice of the optimum measuring program in the precision engineering. Generally speaking, the best scheme could be made by minimizing the functional errors by statistical theory if some definite relationships exist between the measuring result and error factors. However, it will be very difficult to find the best plan using statistics in the case that the certain functional relation between the results and factors can't be found in a dynamic measuring process. Based on grey system theory, a new way for seeking the soundest method of a dynamic process is proposed to solve this problem by grey relational analysis in this paper, which is especially suitable for the complex measuring system where it is difficult to determine the definite relationships among error elements.
