《計量工作》杂志1964年第3期刊有国家科委計量局胡国玙同志所著“測定正多边稜体角值的全組合法一文。这篇文章比較詳细地介紹了按最小二乘法原理测定正多边稜体的全組合方法。以正8边稜体为例导出了由法方程式求出各展开系数,再求出各权系数,从而求得稜体各边对第一边角值的偏差。正如这篇文章最后所指出的,这种求未知数的运算过程相当繁瑣,花費工作量很大。我們过去亦曾对正12边稜体按全組合法进行过測定,但采用了另一种方式运算,可
“Metrology” magazine in 1964 third issue of the National Science and Technology Commission of measurement Comrade Hu Guojuan "Determination of positive polygonal prism angle value of a full set of legal article.This article describes in more detail according to the principle of least squares method is The full combination method of polygonal prisms is given in this paper. Taking the positive 8-edge prisms as an example, the expansion coefficients obtained by the normal equations are obtained, and then the weight coefficients are calculated to obtain the deviation of each edge of the prism to the first edge value. As pointed out at the end of this article, this unknowns calculation process is quite tedious and requires a lot of work. In the past, we also tested the positive 12-edge prisms in a group method, but in a different way Operation, can
