学文网GRE考试与物理相关的词汇
需要GRE考试的，大量练习词汇是非常有必要的，下面是应届毕业生为大家分享有关GRE考试与物理相关的词汇，欢迎大家阅读与学习!
Heat Conduction热传导
原文：When a substance is heated, heat is passed from its hotter part to its cooler part. This way of passing heat is called conduction. Metals conduct heat easily. They are good conductors. Non-metals, such as wood, glass and plastic cannot conduct heat easily. They are bad conductors.
翻译：物质受热时，热量从温度高的地方向温度低的地方传递。这种热的传递方式叫传导。金属容易导热，是良好的导体。非金属，如木头、玻璃、塑料，不易导热，不是良好的导体。
讲解：上文中，substance是指物质，物质也可以用matter来表示。Conduct是传递、传导的意思，做动词时重音在后，读作/ k?n?d?kt/，conduct的名词形式是conduction，导体为conductor。导热，可以说heat conduction，也可以用passing heat来表达。
Travel of Sound声音的传播
原文：Sound is produced when things vibrate, like beating a drum or beating a guitar.Sound has to travel through solid, liquid or air to ears. When the sound is blocked by other things, it become less loud and clear. Sound travels better through liquid that through air. It travels best through solid.
翻译：声音是通过震动产生的，例如敲鼓或弹吉他。声音通过固体、液体或空气传入耳朵。当声音被其他物质阻挡时，声音会变小、变得不清晰。声音在液体中传播比在气体中传播快，在固体中传播最快。
讲解：travel除了指旅行，也可以表示传播，例如travel of sound声音的传播, travel of light光的传播。第一句sound is produced when things vibrate是一个被动句，由be produced构成被动结构;这句话中，vibrate的意思是震动。这段中三个关键词为solid固体，liquid液体和air空气。
Refraction of light光的折射
原文：Air, water and glass can let light pass through. They are called medium. When light passes from one medium to another, such as from water to air, its direction changes. This is called the refraction of light. The words under thick glass look higher up. The chopstick dipped into water looks bent. The rainbow looks curved. These are some examples of light refraction.
翻译：空气、水和玻璃可以使光通过，他们叫做介质。当光从一种介质传播到另一种介质，例如从水射入空气，方向会发生变化，这一现象叫光的折射。厚玻璃下面的字看起来更高。浸入水中的筷子看起来弯曲。彩虹是弯的。这些都是光的折射。
讲解：medium是介质的意思，介质是指能够传播能量的载体。Dip，浸蘸。Curve用作名词是曲线的意思，curved为形容词，弯曲的。
以上一些例子中，句子大多为简单句，语言并不算难。我们可以看到，一些常见的词汇，例如medium媒介，在物理学科中就成为了专有名词。如果有相关的物理背景知识，还是很好理解的。有很多我们日常生活中认识的词汇，在科学背景的材料中似乎就变得难以理解了。这是因为我们欠缺相关的专业知识，不知道这个词在这样的语境下是什么意思。为了避免这种情况，需要多积累广泛的背景知识，并在学习的时候充分调动起来。
