论文摘要
在此评论中,我们讨论了均应扰动方法在非线性微分质量方程中的应用,该方程求解了托尔曼 - 欧彭海默 - 沃尔科夫方程在各向同性和球形对称系统中。我们表明,通过教科书的功率系列方法,人们更容易,直接地获得相同的结果。
In this comment we discuss the application of homotopy perturbation method to a nonlinear differential mass equation that solves the Tolman-Oppenheimer-Volkoff equation for an isotropic and spherically symmetric system. We show that one obtains the same results, more easily and straightforwardly, by means of a textbook power-series method.
