论文部分内容阅读
本文评论了“弹性柱体的扭转理论”一书中钱伟长所写的三章。 第一章“绪论”共有一万五千多字，共计 ２１页，除了占一页半的引言Ｓ１．１，和占半页的结束 语 Ｓ１．８以外，其他几节，除个别几小段外，都是从Ｔ．Ｊ．希琴斯 １９４２与 １９４３年的两篇总结性文 章抄来，而且不注明来源（贝附录１）。在钱伟长自己写的两小段中包含了一小观点上的错误， 他片面地夸大了确定独立的弹性系数的个数这个理论问题在推动柱体扭转问题研究中的作用。 第二章“弹性柱体的扭转理论”除了扭转理论的一般介绍以外，包括了钱的“圣维南扭 转问题的物理假定”一文的内容。本文中指出钱的这篇文章的全部内容包括推导步骤都是从古地 尔［５］（１９３７）的论文抄来的（见附录ＩＩ）。钱只介绍古地尔的非主要结果，而把他的主要结果加 以剽窃。 第九章“变截面圆柱体的扭转”的内容主要是抄自索连尼克·克拉沙［６］一书。 总的来看，这三章中８０％以上的材料几乎是原封不动地抄自别人的著作，余下的也没有什么 创造性的见解，却给读者留下若干错误的论述。
This article reviews three chapters written by Qian Weichang in The Theory of Torsion of Flexible Cylinder. In the first chapter, there are over 15,000 words in total, totaling 21 pages. Except for a half page of introduction S1.1 and a half page of conclusion S1.8, with a few exceptions, All from t J. Two summaries of the Greek scholarly writings of 1942 and 1943 were copied and the source was not specified (appendix 1). Two short paragraphs written by Qian Weichang included a small mistake in perspective. He unilaterally overstating the role of the theoretical issue of determining the number of independent coefficients of elasticity in promoting the study of the problem of cylinder torsion. Chapter 2, “The Theory of Torsion of Elastic Cylinders”, in addition to a general introduction to torsional theory, includes the text “The Physical Assumption of Saint Venant’s Reversing Problem” of Money. The entire article, including the derivation steps, of this article pointing out the money is copied from the thesis of Gudoul [5] (1937) (see Appendix II). Money introduces only the non-main results of the Gudoul, and plagiarizes his main result. The contents of Chapter IX, “Torsion of Variable Cross Section Cylinder” are mainly copied from the book of Solnink Krasha [6]. In general, more than 80% of the materials in these three chapters are copied almost exclusively from the writings of others and the rest have no creative insights, leaving the reader with a few erroneous arguments.
