radioactive decay

基本解释

The point of the experiment is that radioactive decay is a quantum process.
这项实验的关键因素在于放射性衰变是一个量子过程。
But rather than test the radioactive decay using just one method, the researchers used three, involving the elements lead, samarium and neodymium.
但是，相对于仅使用一个方法测试放射性衰变，研究人员测定时使用了三种元素，铅，钐，钕。
Only gravity and a phenomenon called the weak nuclear force, which governs some types of radioactive decay, can bind them—hence the term “weakly interacting”.
只有重力和一种可以支配某些放射性衰变的弱核力能够使其聚集凝固，“弱反应”这一术语由此得名。

Alpha particles are these helium nuclei, and they are the result of radioactive decay.
阿尔法粒子是氦核，它们是放射性衰变的产物。

If there is a gigantic mountain with 5, 000 km height, 50% of this mountain would not respond to radioactive decay.

The heat that keeps the core of the earth molten is primarily radioactive decay—-it is what makes rock into liquid lava.

In the meantime, it remains to be seen how these findings will affect the use of radioactive decay in technological applications.

disintegration of a nucleus that occurs spontaneously or as a result of electron capture. One or more different nuclei are formed and usually particles and gamma rays are emitted (Sometimes shortened to decayAlso called disintegration)
