汉语拼音：

一种粒子。用符号p表示。带正电，电量为160×10-19库，静止质量为电子质量的1836倍。是氢原子核，也是各种元素的原子核的组成部分。原子核中所含质子数等于该元素的原子序数。

• If an anti-Y particle collided with a proton, said proton would turn into a theta particle and a kaon.

  在这个基础上，自然界中仅有的粒子是电子和质子，这告诉我这种空穴只能是质子。

• The net charge of a body might be described by a statement of the excess number of electrons or protons in the body.

  一个物体所带净电荷的量，可以用在这个物体内的过剩电子数或过剩质子数来表示。

• Giant detectors built to look for a hypothetical form of radioactivity in which protons decay never found such a thing.
