Alevel物理学到A2核物理部分,经常会遇到与核有关的单词,像nuclear,neutron,neucleon......见到或者用到的时候总是傻傻分不清楚,下面为大家总结一下,记得收藏哦!
neu·tron
NOUN
复数neutrons
Neutron,名词,中子,是一种组成原子(atom)的particle(粒子),与质子(proton)共同构成原子核(nucleus)。
举个例子,Neutron star 中子星
例句:
The neutron is a subatomic particle, symbol n or n 0, with no net electric charge and a mass slightlylarger than that of a proton.Protons and neutrons constitute the nuclei of atoms.
nu·cle·ar
adj.原子能的;核能的;核武器的;核子的
relating to the nucleus of an atom.
synonyms:
central · innermost · mid · middle · interior · nuclear · the center of · the middle of · theheart of
antonyms: outer·denoting, relating to, or powered by the energy released in nuclear fission or fusion.
"nuclear submarines" · "nuclear energy"
·denoting, possessing, or involving weapons using nuclear energy.
"nuclear nations" · "a nuclear bomb"
Nuclear作为形容词,用来修饰名词,在核物理这部分可以组的说法很多,
举个例子,
Nuclear physics 核物理(指核物理这个物理分支)
Nuclear power 核能
Nuclear decay 核衰变
Nuclear fusion 核聚变
Nuclear fission 核裂变
Nuclear radiation 核辐射
Nuclear reaction 核反应
例句:
A nuclear weapon is an explosive device that derivesits destructive force from nuclear reactions, eitherfission (fission bomb) or a combination of fission andfusion (thermonuclear weapon).
nu·cle·us
复数 nuclei
NOUN
the central and most important part of an object, movement, or group, forming the basis for its activityand growth.
"the nucleus of a film-producing industry"
synonyms:
core · center · central part · most important part · heart · nub · hub · middle · midpoint · eye · kernel · focus · focal point · pivot · crux · navel · omphalos
· physics
the positively charged central core of an atom, consisting of protons and neutrons and containingnearly all its mass.
· biology
a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded bya double membrane, containing the genetic material.
· anatomy
a discrete mass of gray matter in the central nervous system.
· astronomy
the solid part of the head of a comet.
Nucleus,名词,有核心的意思,在物理上指center,中心部位,比如说,原子核处在原子的中心,而原子核就是nucleus,此处nucleus指的是一种particle(粒子)
复数为nuclei,意思是多个原子核,这个单词用的也很多。
例句:
The nucleus is the small, dense region consisting of protonsand neutrons at the center of an atom.
nu·cle·on
NOUN
physics
a proton or neutron.
复数:nucleons;
Nucleon,名词,核子,也是一种particle(粒子)。
核子(nucleon)分两种,proton(质子)或neutron(中子)。
举个例子,原子(atom)由原子核(nucleus)+核外电子(electrons)组成,原子核由1个或多个核子(nucleon)组成,等同于原子核由质子或质子和中子组成。
mass number=nucleon number= No. of protons + No.of neutrons
例句:
In chemistry and physics, a nucleon is one of the particles that makes up the atomic nucleus. Each atomic nucleus consistsof one or more nucleons, and each atom in turn consists of a cluster of nucleons surrounded by one or more electrons. There are two known kinds of nucleon: the neutron and the proton. The mass number of a given atomic isotope isidentical to its number of nucleons.
