摘　　要：在保留Ａｉｍａｒ的文章中关于恒等逼近算子的核条件的同时，附加较自然的条件，在对空间及函数的条件都减弱的情况下，证明了点收敛意义下的逼近等式：ｌｉｍε→０＋∫Ｘε－１φ（ｄ（ｘ，ｙ）ε）ｆ（ｙ）ｄμ（ｙ）＝ｆ（ｘ）We developed a method to calculate the values of a special kind of determinants about Yang Hui Triangle,which had been brought up by Mr Jiang Xingwu,and another two kinds of determinants about Yang Hui Triangle raised by ourselves. Accidentally we discovered how to calculate a kind of determinants composed of combinatorial numbers.

关 键 词：齐型空间 恒等逼近 点收敛 卷积算子 逼近算子
