再生核空间W_2~1(R)中的分段投影插值

The Piecewise Projecting Interpolation in the Space W+1~2(R)Processing Reproduction Kernel

本文在具有再生核的空间W21（R）中讨论分段插值问题,给出W21（R）的再生核的解析式,并构造一个分段插值公式。

This paper daels with the piecewise interpolation problem in the space W1(R processing reproducing kernel and proposes the analytic expression of reproducing kernel as well as the interpolation formula.
