对于Ｓｏｂｏｌｅｖ类Ｗ１，ｎｌｏｃ（Ω，Ｒｎ）的ｎ维（Ｋ１，Ｋ２）－拟正则映射，建立了其偏微商的Ｌｐ可积性结果，从而得到映射的Ｈ¨ｏｌｄｅｒ连续性；并且给出了其对一类拟线性椭圆型方程组先验估计的应用

The L p integrability of the partial derivatives of (K 1,K 2) quasiregular mappings is established in Sobolev class ofW 1,n loc (Ω,R n) and a Hlder continuity of the mappingis obtained. Moreover, this result is applied to an apriori estimate of weak solutions for a class of quasilinear elliptic systems.
