本文提出了一种新的非对称阿贝尔反演方法，适用于环形等离子体系统等离子体诊断（如干涉测量或光谱学）中不对称观测方向垂直的非对称数据。该方法利用积分量奇偶分离得到的权函数来确定非对称局部值。为了证明这种新方法的有效性，我们建立了一个假设的数据集，从而得到一个有效的局部值。
A new asymmetrical Abel inversion is presented for application in asymmetrical data which is obtained from plasma diagnostics (for instance, interferometry or spectroscopy) on the toroidal plasma system, and in which asymmetry exists normal to the direction of observation. In this new numerical method a weight function, which was obtained by separating the integrated quantity into odd and even parts, was used for determination of the asymmetrical local value. To demonstrate the usefulness of this new method, we set up a hypothetical data set, which resulted in a valid local value.
