这本书相当简洁，由大约160页可读性很强的文字、表格和图表组成。然而，对于工程专业的学生和其他专业的执业工程师来说，这本书的一些特点有损于它作为入门或初步步骤的作用。例如，删除关于矢量量处理的附录，而利用空间扩展处理原子和分子结构以及能量释放的章节，这可能会更好，因为它们是简化的宝石，肯定会从作者的扩展处理中受益。这本书的一个令人困惑的方面和一个主要的错误是在一些数学关系的详细推导中的错误数量（尽管关系本身看起来是准确的），以及在一些图表的编号和引用中。从语法和标点符号的证据来看，这篇文章必须经过仔细的校对，这些错误令人失望。最后一章的最后几页将讨论这一点，其中有一张图表表明，对于总重量超过50万磅的运载火箭，起飞时所需的推力明显小于发射重量！有这样的缺陷的65型。收购价格太高。这是一个遗憾，因为在他的主题和他的方法，作者选择了很好。删除错误，以平装本的形式以较低的价格出版，我会毫不犹豫地推荐它作为任何对太空飞行感兴趣的工程师书架上的有用补充。G.

The book is quite concise, consisting of some 160 pages of very readable text, tables and diagrams. There are, however, some features which detract from a book claimed to serve as a primer, or preliminary step, for the engineering student and the practising engineer in other branches of the profession. It might have been better, for example, to delete the appendix on the treatment of vector quantities in favour of using the space to extend the sections dealing with atomic and molecular structure and energy release which, gems of miniaturisation that they are, would surely have benefited from an expanded treatment by this author. A puzzling aspect of this book and a major fault is the number of mistakes in the detailed derivation of some of the mathematical relationships (although the relationships themselves appear accurate), and in the numbering and referencing of some of the diagrams. In a text which, from the evidence of its grammar and punctuation, must have been meticulously proof read, these errors are a disappointment. The culmination of this is reserved for the last few pages of the last chapter in which one diagram shows that for launch vehicles with an all-up-weight in excess of 500 000 lb the thrust required at lift-off is significantly less than the launch weight! With defects like this the 65s. purchase price is too high. This is a pity, because in his subject and in his approach, the author has chosen well. Remove the errors, publish it in paperback form at a reduced price and I would have no hesitation in recommending it as a useful addition to the bookcase of any engineer with an interest in space flight.—G.
