isotope作为名词的时候,其近义词以及反义词有s、isotopes等。
Isotope是由同种元素的原子构成的若干种不同的形式,其中原子的质量数相同但原子核内的中子数不同。它是化学和物理学中经常用到的一个词汇,下面从四个方面进行详细介绍:
1.定义和背景
Isotope一词来源于希腊语Isos(相等)和topos(位置)两个词,意为具有相等位置的原子。早在xx年,英国化学家Frederick Soddy就提出了这个概念。
2.应用领域
Isotope在许多领域得到了广泛的应用,包括核能、医学、地球科学、天文学以及环境科学等。
3.分类和表示法
Isotope可以根据其中子数来进行分类,常用缩写法表示,如氢的三种同位素分别表示为:
- 普通氢:^1H
- 氘:^2H
- 氚:^3H
4.常见示例
以下是一些常见的示例:
- Carbon-14 is a radioactive isotope used in dating ancient artifacts.(碳14是一种放射性同位素,用于测定古代文物的年代。)
- Scientists use isotopes to study the migration patterns of birds.(科学家利用同位素研究鸟类的迁徙模式。)
- The patient received a PET scan, which uses isotopes to detect cancer cells.(患者接受了PET扫描,该扫描使用同位素来检测癌细胞。)
- Uranium-235 is a fissionable isotope used in nuclear reactors.(235是一种可的同位素,用于核反应堆中。)
- Hydrogen-2, also known as deuterium, is used in nuclear magnetic resonance imaging (MRI).(氢2,也称为重水,用于核磁共振成像(MRI)中。)
