If we solve these equations by the conventional method, we may acquire certain results which disagree with objective reality. Thus it may cause difficulties in describing the inner laws of the corresponding physics. To illustrate what I mean, let us consider the following cases.展开更多

INTRODUCTION Solar force-free magnetic field with constant α, has been much studied by many authors, such as Nakagawa and Raadu, Seehafer, Chiu and Hilton, Alissandrakis. However, the solutions of the problem presented by them are not unique, and the reliability of these solutions has more or less limitations. Moreover, most solutions展开更多
