如果已知很多环境变量，每次换机器都是相同配置，环境变量配置窗口操作觉得麻烦，可以考虑这个直接注册。 只需要在reg.txt中按行写入：环境变量名=环境变量值(If many environment variables are known, each machine change is the same configuration, environment variables configuration window operation is troublesome, you can consider this direct registration. Just write in reg. TXT by line: environment variable name = environment variable value)

DESIGN - Hardin and Sloane Spherical Designs DESIGN implements a number of Hardin and Sloane spherical designs. A set of N points which lie on the sphere is called a spherical T-design if the integral on the surface of the sphere of any polynomial of degree at most T is equal to the average value of the polynomial evaluated at the set of points. Note that the degree of a polynomial is the highest degree of any of its terms, and that the degree of a term like XAYBZC is A+B+C.
