摘要

在试图得到四尖脉冲形状的过程中，作者意外地发现了一个非常有趣的结果。具体来说，发现两个或多个麦克斯韦分布的组合不仅可以形成四尖点脉冲，而且还可以产生几个非麦克斯韦分布。这个结果非常有吸引力，在身体上是可以接受的。因为有两种分布的系统会进入第三种非平衡态，也就是说两个麦克斯韦分布会得到第三种分布，以此类推。我们的研究结果对与外部能源（如太阳风）相连的等离子体系统具有重要意义。

Non-Gaussian distributions in solar wind plasma: data analysis and source

While trying to arrive at the four-picket pulse shape, the author of this work accidently found a very interesting result. Specifically, it is found that not only four-picket pulse can be formed from combination of two or more Maxwell distributions but additionally several non-Maxwellian distributions can be generated. This result is very attractive and physically acceptable. Because, systems having two types of distributions will go to a third state that is non-equilibrium state, meaning that two Maxwellian distributions will give a third distribution and so on. Our results are significant for plasma systems connected to external energy source such as solar wind.

期刊介绍： Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered. The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing. Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
