摘　　要：有限元法能方便地处理非线性介质特性,其所形成的代数方程具有系数矩阵对称正定、稀疏等特点,求解容易、收敛性好、占用计算机内存量较少。该方法在热喷涂的数值模拟中应用较多。国内外学者在热喷涂数值模拟方面做了大量工作,为热喷涂的发展提供了一定的理论依据和技术手段。The finite element can be easily used to process the nonlinear media characteristics. The algebra equation formed by the finite element has characteristics such as the positive definite of coefficient matrix symmetry, sparseness, easy solving, better astringency, and use less memory. This method is widely used in the numerical simulation of thermal spraying. The scholars＇ in China and abroad work on the numerical simulation of thermal spraying technology and provide the theory evidence and technology approaches for development of thermal spraying.
