精度分配的多重卷积算法

为了更精确地进行精度分配,必须利用现代误差综合理论,其中颇为有效的是多重卷积综合法.但由于其计算工作量大,用于精度分配时计算更为繁复.为能满意地解决此问题,在各种精度分配原则的基础上,采用预设因子方法,避免了多次寻优过程中的反复计算,使精度分配可以方便、迅速地求出精确结果。

An Algorithm of Multiple Convolution for Precision-Distribution

In order to conduct precision-distribution more precisely, it is necessary to make use of contemporary theories of error synthesis, among which the algorithm of multiple convolution is especially efficient. Yet it necessitates fairly large amounts of calculation, takes much time and thus becomes rather complicated when applied to problems in precision - distribution. In order to solve this problem satisfactorily, it is proposed to settle the factors beforehand on the basis of various principles for precision-distribution. With this complicated calculations in the process of repeated optimization can be prevented, and problems of precision-distribution can be conveniently and more promptly solved, attaining eventually accurate results.
