摘　　要：介绍了等离子体椭圆截面的Abel逆变换方法,并和圆截面的Abel逆变换方法进行了比较。给定一个探测阵列对一个辐射源函数的测量结果,分别用Barr方法、等值同心圆方法和幂级数方法进行了椭圆逆变换,结果表明该方法的可靠性可应用于实验数据处理中。A method for transforming the observed radiance into a radial distribution of the emitters in the plasma is described.It is applicable to the analysis of emissions from a thin plasma with elliptical symmetry.The method shows that any numerical method for calculating emission distributions from a circular plasma can be easily adapted for plasmas with arbitrary ellipticity.
