摘要
本文在SP．n矩阵的判定和分解的基础上，专门论述SP．n矩阵反问题．得出了方程反问题和特征值反问题在SP．n阵类中有解的充要条件．
Based on the decomposition and judgements of this symmetrical partial negative, in the essay ananalysis is made especially in the inverse question of Symmtrical partial negative and proves the necessary andsufficient condition that equation inverse question and characteristic value inverse question can be carried out inthe symmetrical partial negative.
