Because of the non-completion of the concepts of regularity in some textbooks on mathematical analySis and differentical geometry,this paper investigate the geometrical characteristics and decisive methods of all types of non -regular points on curves according to the concepts of regular curves.

Boundary regularity results for viscosity solutions of Poisson s equation and fully nonlinear uniformly elliptic equations under the Dini condition are obtained by use of Caffarelli s perturbation method, which give a simple proof of Theorem 4.
笔者利用Caffarelli扰动方法,证明了Poisson方程和完全非线性一致椭圆型方程在Dini条件下其粘性解的边界正则性,从而给出了文[8]定理4。
The boundary regularity for a class of weakly harmonic maps which maps into sphere and satisfies a quasi monotonicity inequality is discussed.
