摘　　要：采用Ｇａｕｓ数值积分法将光学厚柱对称等离子体径向发射系数的广义Ａｂｅｌ方程离散成系数是上三角矩阵的线性代数方程组，计算特别简单、省时间，具有２阶精度。Gauss numerical integration is applied to compute the radial emission coefficients in Optically Thick,Cylindrically Symmetric Plasmas.Using the integration,the generalized Abel equation is separated into a system of linear algebraic equations and the coefficient matrix of the system is an upper triangular matrix,so the interpolation,which has second order of accuracy,is very simple to compute and less computation time is required.
