材料英语翻译答案

分子以共价键结合成分子链的过程。 3. 接枝聚合物分子由带有一个或者多个侧链的主链构成，特殊类型接枝聚合物包含星型形状、梳子形状、刷子形状。

4. 一些生物型聚合物由许多不同但结构相近的单体组成，如多聚核苷酸由核苷单体组成。 3.汉译英

Persistent length cross bonding Polar monomer nucleic acid Polymerization polyelectrolyte 1. Most commercially important polymers today are entirely synthetic and produced in high volume, on appropriately scaled organic synthetic techniques.

2.Some biological polymers are composed of a variety of different but structurally related monomers, such as polynucleotides composed of nucleotide subunits.

3. A polymer molecule with a high degree of crosslinking is referred to as a polymer network. 4. In polymers, however, the molecular mass may be expressed is terms of degree of

polymerization, essentially the number of monomer units which comprise the polymer. Unit16： 2.英译汉

工程材料 生成的材料 增强混凝土 金属基复合材料 陶瓷基复合材料 三明治结构

1. 例如，多相金属在微观层次上是复合材料，但广义上讲，复合材料这个术语，指的是两个或多个不同材料之间依靠机械力结合而形成的材料。

2. 许多情况下，复合材料有一个本相：它是连续的，叫做基体，还有一个分散的、不连续相，叫做增强相。

3. 先进复合材料是树脂和纤维的结合，通常是碳纤维/石墨、凯夫拉纤维、玻璃纤维和树脂。纤维提供高刚度，周围的聚合物树脂基体将整个结构固定起来。

4. 如果复合材料被正确地设计和加工，它具备增强体的强度、基体的韧性，获得所需要的结合的性质，这种性质是任何传统单一材料所不具

备的。 3.汉译英 Composite

1.A composite retains its own distinctive properties that cannot be achieved by any of the components acting alone.

2.Carbon-epoxy composites are two thirds the weight of aluminum, and two and a half times as stiff. Composites are resistant to fatigue damage and harsh environments, and are repairable. 3.From the concept of composites, reinforced plastic, metal-matrix composite, ceramic-matrix composite and concrete, etc, are all composites.

4.In fiber-reinforced composites, the fiber is the primary load bearing component. Fiberglass and carbon fiber components are examples of
