The Stability of Solution of the Oblique Derivative Problem for the First Order Nonlinear Elliptic System (Ⅱ)

在本刊总第２８期所载本文（Ｉ）的基础上给出边值问题的解的先验估计式，进而利用解的估计式导出相应边值问题解的稳定性。

This paper discusses the stability of solution of the oblique derivative problem for the nonlinear elliptic system of first order equations. This result is derived with the help of a priori estimation of solution for relative boundary value problem. The main purpose of this part(I) is to give the formulation and conditions of the problem, the equivalence theorem and the expression of solution of the boundary value problem.
