摘要
本文分析讨论了轴对称等离子体流场中光谱发射率的求解问题,发现用多项式分段拟合Abel方程正向积分求解的方法,所得结果与以往文献比较,其计算精度高、误差传递系数小。
This paper presents a method to solve the Abel equation for the spectral emissivity in the flow field of axisymmetrical plasma.It is found that the result obtained by using polynomial fitting forwardAbel equation has a higher precision and smaller error transfer coeff-icients compared with those of the references.
