摘要
在试验设计的选择中,选取“球面”的方差函数的设计,能保证估算的响应函数,在到设计数中心是相等距离的全部点上,具有常数的方差。
While choosing the experimental design,one may choose the variance function design of the sphere,so as to ensure that the estimated relevant functions have variance of constants at all points that have equal distance to the centre of the design.
