关于椭圆方程组正则性的一个注记

A note on the regularity for theelliptic systems

椭圆型偏微分方程组弱解的正则性，是偏微分方程和变分分析研究中的重要课题．本文在文献［Ｃ］的基础上研究线性方程组当系数不连续时弱解的正则性．对有界可测系数，证明了一些部分正则性结果，当系数用于Ｈ１．ｎ空间时，证明了弱解的Ｈｏｌｄｅｒ连续性．

In this paper we study the regularity of weak solutions for the linear elliptic systemsin the case in which the leading coefficients are not continuous. We obtain some barnalregulaity results and some H6lder reqularity results.
