“太阳线性无力场评注和快速傅氏分析法的应用”一文对太阳线性无力场的工作做了一些评注,在此基础上对快速傅立叶方法的应用提出了改进的计算方法.该文的某些观点值得商榷,有必要对其中存在的问题予以澄清.另外,对该文关于快速傅氏分析法的工作从理论的角度提出看法.
The paper "Comments on Solar Linear Force-free Field and Application of FFT Analysis (Song & Zhang, 2004, 2005)" made some comments on linear force-free field problems and proposed a so-called improvement on the application of FFT. We argue that some points in Song & Zhang on available methods are misleading or incorrect. The FFT technique proposed in Song & Zhang is also controversial. Therefore some of their conclusions should not be solid.
