高分子材料工程专业英语课文翻译Polymer Science and Polymer Engineering are closely related andoften used interchangeably. Polymer Science is concerned with the chemistry and physics of polymers, while Polymer Engineering teaches students how to design and manufacture polymer products. No matter which field you choose, there is constant innovation and new developments in the field of Polymer Science and Engineering.高分子科学和高分子工程密切相关，常常互换使用。
高分子科学研究聚合物的化学和物理学，而高分子工程则教授学生如何设计和制造聚合物产品。
无论您选择哪个领域，高分子科学和工程的领域中都不断有创新和新发展。
Polymers are large molecules that are made up of repeating units called monomers. These molecules are characterized by their high molecular weight, which gives them unique properties such as strength, elasticity, and durability. There are many types of polymers, including plastics, rubbers, and fibers.聚合物是由称为单体的重复单位组成的大分子。
高分子英语课文翻译()
unit11.Not all polymers are built up from bonding together a single kind of repeating unit. At the other extreme ,protein molecules are polyamides in which n amino acide repeat units are bonded together. Although we might still call n the degree of polymerization in this case, it is less usefull,since an amino acid unit might be any one of some 20-odd molecules that are found in proteins. In this case the molecular weight itself,rather than the degree of the polymerization ,is generally used to describe the molecule. When the actual content of individual amino acids is known,it is their sequence that is of special interest to biochemists and molecular biologists.并不是所有的聚合物都是由一个重复单元链接在一起而形成的。
在另一个极端的情形中，蛋白质分子是由n个氨基酸重复单元链接在一起形成的聚酰胺。
尽管在这个例子中，我们也许仍然把n称为聚合度，但是没有意义，因为一个氨基酸单元也许是在蛋白质中找到的20多个分子中的任意一个。
在这种情况下，一般是分子量本身而不是聚合度被用来描述这个分子。

To contrast the difference, the molecular weight of common salt is only 58。
5, while that of a polymer can be as high as several hundred thousand, even more than thousand thousands. These big molecules or ‘macro—molecules' are made up of much smaller molecules, can be of one or more chemical compounds. To illustrate, imagine that a set of rings has the same size and is made of the same material. When these things are interlinked, the chain formed can be considered as representing a polymer from molecules of the same compound. Alternatively, individual rings could be of different sizes and materials，and interlinked to represent a polymer from molecules of different compounds.什么是高聚物?首先，他们是合成物和大分子,而且不同于低分子化合物，譬如说普通的盐.与低分子化合物不同的是，普通盐的分子量仅仅是58.5,而高聚物的分子量高于105，甚至大于106.这些大分子或“高分子”由许多小分子组成。

Polymer Materials Engineering Professional EnglishText TranslationIntroductionAs an interdisciplinary field incorporating elements of both chemistry and engineering, Polymer Materials Engineering seeks to synthesize, process, and analyze polymers and polymer-based materialsfor a variety of industrial applications. Materials in this field can range from thermoplastics to thermosets, from elastomers to composites, and from gels to liquid crystals. The study of Polymer Materials Engineering is crucial for industries such as manufacturing, automotive, aerospace, healthcare, and electronics.To master Polymer Materials Engineering, one must not only have a solid foundation in engineering, chemistry, and physics, but also be proficient in technical English. Therefore, reading and translating English texts related to Polymer Materials Engineering is a vital skill for students and professionals in this field.In this article, we will provide a translation of an English text related to Polymer Materials Engineering, with the m of improving readers’ understanding and usage of specialized vocabulary in this field.Text TranslationOriginal English text:Rightly or wrongly, a connection often is made between themechanical performance of a polymeric material and its degree of crystallinity. The inference, however, can be incorrect as many other factors affect the mechanical response of polymer materials. Simply stated, crystalline regions are usually stronger and stiffer than amorphous regions. Generally, the degree of crystallinity that yields optimum properties depends on the polymer type and on the application.Translated text:通常我们会认为高分子材料的力学性能与其结晶度相关联，这种推论并不总是正确的。
