摘要
本文基于z-箍缩条件下的两种等离子体密度分布形式:高斯分布和双峰分布,详细比较了逆阿贝尔变换的三种方法,发现傅里叶汉克尔变换方法对噪声不敏感,对两种等离子体分布形式均有同等好的表现,并好于数据经过降噪处理后的其它两种变换方法,同时该方法程序实现更为简单.
Comparision of three methods for abel inversion based on two profiles of z-pinch plasma： the Ganssian profile and the double-peak profile.Results show that Fourier-Hankel method is insensitive to noise and same effective for two profiles of plasma. In addition,Fourier- Hankel method is found to outperform two other methods,and the method programmed is simpler than others.
