摘要 X是S2的有限子集,它的网格范数为hX.文章利用分析工具对hX的上、下界估计进行了一些研究和探讨.同时给出了所得结果在球面数值分析与逼近中的具体应用. X is a subset of S^2 , and its mesh norm is hx . This paper makes some investigations into the estimates of upper and lower bounds of hx with the help of analysis. And specific applications of the results are given in numerieal analysis and approximation on the unit sphere.
