solution by successive approximation

基本解释

In math terms, they are a closed-form solution; lesser artists literally solve the same problems by successive approximation.
使用数学术语，它是一个封闭的形式解。这是大艺术家的擅场，小艺术家们则往往用一点点地逐渐接近来解决问题。
The mathematical model is based on the calculation of geometrical figures by graphic method and the solution is obtained by successive approximation.
数学模型系以对图解法几何图形的解算为依据，并以逐步逼近计算法求解。
Firstly, by use of the successive approximation method and a series of classical estimates, the local existence and uniqueness of weak solution are proved.
利用逐次逼近方法和一系列经典的估计，证明了弱解的局部存在性和惟一性。
