unknown solution

Consider an elliptic system in diagonal form of which the nonlinear terms are of quadratical growth respect to the gradient of the unknown solution.

考虑一类对角型椭圆组，它的非线性项关于未知解的梯度为二次增长。

The above methods have their inadequacies, the specific values of key parameters of binary tree application are unknown. So the solution based on the assumptions of parameter leads to more weakness in the solution of practical problems.

上述方法亦有其不足之处，二叉树法应用中由于关键参数的具体数值是未知的，其求解需要基于一定的参数假设，也就导致了在实际问题的解决上较为乏力。

This paper discusses the relationship of the circuit structure of dynamic circuit and the ordering of differential equation, effect of selection unknown variables on the solution of equation and the calculations of special solution and initial values.

分析了电路结构与微分方程阶次的关系，电路未知变量的选择对求解方程的影响，特解和初始值的计算方法。

This can transform the scattering wave problem into the problem to solve the unknown coefficients of solution series. Thus the problem was converted into the problem of linear algebraic equations by method of truncation coefficient.

这样就将求解散射波问题转换为求解散射波级数的未知系数问题，通过截断系数，转换为线性代数方程组问题。
