a proton
A proton has a positive charge.
质子带正电荷。
质子
先理解核心含义,再看它在真实句子里的用法。
质子
a stable particle with a positive electric charge equal to an electron's negative charge
A proton has a positive charge.
质子带正电荷。
质子;带正电的稳定粒子,电荷量与电子负电荷相等
a stable particle with positive charge equal to the negative charge of an electron
A proton has a positive electric charge.
质子带正电荷。
The number of protons in an atom determines its element.
原子中的质子数决定了它的元素。
The scientist measured the mass of a single proton.
科学家测量了一个单个质子的质量。
A proton has a positive charge.
质子带正电荷。
复数形式常用来泛指质子这一类粒子。
Protons are found in the nucleus.
质子存在于原子核中。
proton作定语修饰名词时用单数形式。
A proton beam is used in cancer treatment.
质子束用于癌症治疗。
Not this
Proton and neutron are in the nucleus.
Use this
Protons and neutrons are in the nucleus.
英语可数名词表示复数时需加-s。汉语名词无复数变化,因此易漏。句中proton和neutron均为可数名词,且主语所指为复数,故用protons和neutrons,与are一致。
Not this
Protons are particles of light.
Use this
Photons are particles of light.
proton(质子)与photon(光子)拼写相近但含义不同:proton是原子核内的带正电粒子,photon是光的量子。说“光的粒子”应用photons。
Not this
Proton has a positive charge.
Use this
A proton has a positive charge.
proton是可数名词单数,在句中作主语时不能没有限定词。汉语无冠词,学习者常漏用。指一个质子或泛指时需加a。

质子束
The cancer patient received treatment with a proton beam.
这位癌症患者接受了质子束治疗。
质子疗法
Proton therapy targets tumors more precisely than traditional radiation.
与传统放疗相比,质子疗法能更精确地瞄准肿瘤。
质子泵抑制剂
The doctor prescribed a proton pump inhibitor for his acid reflux.
医生为他的胃酸反流开了质子泵抑制剂。
质子交换膜
The fuel cell uses a proton exchange membrane to generate electricity.
这种燃料电池利用质子交换膜发电。
质子数
The proton number determines which element an atom belongs to.
质子数决定原子属于哪种元素。
质子衰变
Scientists have not yet observed proton decay in experiments.
科学家尚未在实验中观察到质子衰变。
(出自电影《星球大战》)质子鱼雷是唯一能击中这个目标的武器。
A proton is a subatomic particle with a positive charge.
质子是带正电荷的亚原子粒子。
Use proton naturally, then get feedback on meaning, tone, grammar, and phrasing.
Revisit a common error or keep this word in your review list.
联想:proton 以 pro 开头,pro 有“支持/正面”的意思,质子带正电,所以记住它就是质子。
语域:neutral 常见场景:粒子物理学讨论、化学课堂、科学文献 proton 是科学术语,通常用于物理、化学等学科的教学或学术讨论,属于中性偏正式的词。日常口语中较少见,多出现在教科书、论文或科普内容中。
真正同韵:photon /ˈfəʊtɒn/ 与 proton 同韵。形近但音异:neutron /ˈnjuːtrɒn/、electron /ɪˈlektrɒn/ 以 /trɒn/ 收尾;cotton /ˈkɒtən/、button /ˈbʌtən/ 以 -ton 拼写但读 /tən/;ton /tʌn/ 拼作 -ton 但发音不同。
