行星磁场。半个多世纪前，太阳风的存在实际上是基于对彗星离子尾巴的研究而预测的[2]。众所周知，这些尾巴是各种等离子体过程的自然场所。一些非常复杂的数学模型已经成功地解释了观测中尘埃尾巴的形状，但人们理解这是一个非常复杂的问题，因为到目前为止开发的理论是关于完美形状的尘埃颗粒的，而在现实中，它们根本不是。所有这些信息都可以在这本书中找到。它以一个简单易懂的一般介绍开始，谈到了彗星的一些基本方面，它们的分类，一些统计数据和历史观点，以及航天器与它们的相遇。但是，关于彗星的主要特征的部分需要澄清一下。从它的写作方式来看，如果没有一些侦探工作，读者可能会发现自己从一开始就无法说出这些特征。对于一些本应显而易见的东西，其特征不知何故被模糊地定义了。如果它们以清单的形式而不是段落的形式给出，情况会好得多。从第二章开始，这本书的内容变得更加具体。诸如彗星的起源、它们的动力学、物理方面、光谱和尘埃粒子的性质等主题都在这里讨论。正如可以预期的那样，这涉及到大量的数学、物理和化学知识；它需要原子物理、光谱学(原子和分子)以及气体和辐射定律的专门知识。高级本科生肯定会发现一些物理方程很熟悉，但尽管如此，在学习其中一些章节之前，最好先温习一些数学物理。总而言之，如果读者不讲究叙事和流畅，更不用说本可以很容易避免的打字错误，这本书是彗星研究初学者的一本很好的教科书。对于那些希望增加知识和理解的人来说，每一章末尾的问题部分特别有用。参考文献列表被分成几个标题，这样读者就可以很容易地聚焦于他们希望进一步研究的主题。这本专著本可以编辑和校对得更好，因为句子在某些地方脱节，但它的目的是为那些寻找冷酷、确凿事实的人提供一本教科书。唯一遗漏的是缩略语和物理量的列表，和/或书末尾的一些基本数学。
planetary magnetic fields. More than half a century ago, the existence of solar wind was actually predicted based on the study of the ion tails of comets [2]. These tails are known to be the natural places for various plasma processes. Some very sophisticated mathematical models have successfully explained the shape of dust tails in observations but it is understood that this is a very complex subject as the theories developed so far are for perfectly shaped dust particles while, in reality, they are anything but. All of this information can be found throughout this book. It starts with an easy-read general introduction that talks about some basic aspects of comets, their classification, some statistics and historical perspective as well as spacecraft encounters with them. But, the section on the main characteristics of comets needs a bit of clarification. From the way it is written, without some detective work, readers could find themselves unable to name these characteristics from the get-go. For something that should have been obvious, the characteristics are somehow unclearly defined. It would have been a lot better if they were given in the form of a list rather than paragraphs. From the second chapter onwards, the book progresses to be more specific in its contents. Topics such as the origin of comets, their dynamics, physical aspects, spectra and nature of dust particles are among those covered here. As can be expected, there is a lot of mathematics, physics and chemistry involved; and it requires specific knowledge of atomic physics, spectroscopy (atomic and molecular) and gas and radiation laws. Advanced undergraduates will definitely find some of the physics equations familiar but all the same, it is best to brush up on some mathematical physics before tackling some of the chapters. To conclude, if readers are not particular about narrative and flow, not to mention the typing errors that could have easily been avoided, this makes a good textbook for beginners of comet studies. The problem section at the end of each chapter is particularly useful for those who wish to increase their knowledge and understanding. The list of references is broken up into several headers that makes it easy for readers to zero in on topics they wish to investigate further. This monograph could have been edited and proofread better as the sentences are disjointed in places but it serves its purpose as a textbook for those looking for cold, hard facts. The only things missing are lists of acronyms and physical quantities, and/or some basic mathematics at the end of the book.
