1. be referred to as, be known as : 称为
2. (as) compared to (with): 与…相比, 同….比较起来, 与…相对应
3. structure sensitive, structure-insensitive properties
❖ 专业英语和普通英语的区别 一. 词义特点
1. 根据词类辨明词义
e.g: (1) Round (adj.) surface reflector is a key unit for the
solar energy device. 曲面反射器是太阳能装置的关键元件。
( 2) This is the whole round (n.) of knowledge. 这是全部知识范围。
二. 句子结构特点
1. 句子长 2. 被动语态多
e.g: The rate at which work is done is called power. 3. 后置定语多 4. 名词化结构多
e.g: to control the machine ---- the control of the machine
4. 联系上下文活用词义 e.g: (1) There is no physical contact between tool and workpiece. 工具和工件之间没有有形（直接）的接触。 (2) High-speed grinding does not know this disadvantage 高速磨削不知道（存在）这个缺点。
2. 区分场合确定词义（不同的场合，词义也不一样。要根据 上下文和语言环境来确定词义） e.g: (1) pig: 猪 ~ iron 生铁
(机械专业) ~ metal 金属锭 ~ copper 生铜
(2) dog: 狗 (机械专业) ~ 鸡心夹头, 挡块
3. 按照习惯搭配词义 e.g: (1) I have a short memory. (2) This biscuit eats short. (3) Indeed he has a short temper.
1. the better…. the more quickly and wisely : 越….越…..
2. a given design: 某个设计
❖ Generally, a material property is the measured magnitude of its response to a standard test performed according to a standard procedure in a given environment.

Lesson 1 Introduction for Materials
❖ Designers and engineers are usually more interested in the behavior of materials under load or when in a magnetic field than in why they behave as they do.
make sth. + 形容词(sth. be make =形容词): 使….怎么样
the properties are made available : 使……可获得
❖ Frequently such information is tabulated for roomtemperature conditions only, so when the actual service conditions are at subfreezing or elevated temperatures, more information is needed.
1. are …. more interested in…. than in 对…..比对…..更兴趣 2. under load ：承载时
❖ Yet the better one understands the nature of materials and the reasons for their physical and mechanical properties the more quickly and wisely will he/she be able to choose the proper material for a given design.
