单词α衰变的英汉对照例句


α衰变理论用了这种模型。
The theory of alpha decay utilizes this model.
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.
半衰期是各种不稳定原子核的特性,是它们衰变的特殊方式。α衰变和β衰变一般比γ衰变为慢。
Half-lives are characteristic properties of the various unstable atomic nuclei and the particular way in which they decay.alpha decay and beta decay are generally slower processes than gamma decay.
放射性的主要过程有α衰变、β衰变和γ衰变。1934年发现通过人工蜕变,普通物质也能诱导出放射性来。
"The main processes of radioactivity are alpha decay beta decay and gamma decay.in1934it was discovered that radioactivity could be induced in ordinary matter by artificial transmutation"
放射性系:四组不稳定的重原子核,通过一系列α衰变和β衰变直至达到稳定的核为止。
Radioactive series: any of four sets of unstable heavy atomic nuclei that undergo a series of alpha decay and beta decay until a stable nucleus is achieved.
