单词α粒子的英汉对照例句


α粒子是从天然放射性蜕变得到的带正电的氦核。
Alpha particles are positively charged helium nuclei obtained from natural radioactive decay.
β衰变过程使母核增加或减少一个单位的正电荷而不改变它的质量数。虽然与γ衰变或α衰变相比,β衰变是一个较慢的过程,但β粒子的穿透距离要比α粒子的大几百倍。β衰变的半衰期为几个毫秒或更长。
The process of beta decay increases or decreases the positive charge of the original nucleus by one unit without changing the mass number.though beta decay is in general a slower process than gamma or alpha decay beta particles can penetrate hundreds of times farther than alpha particles.beta decay half-lives are a few milliseconds or more.see also radioactivity.
玻色子具有零或整数自旋状态,并且任意数目的相同粒子占据相同量子状态的统计学规则的粒子,如光子、π介子或α粒子
Any of a class of particles such as the photon pion or alpha particle that have zero or integral spin and obey statistical rules permitting any number of identical particles to occupy the same quantum state.
