radioactive decay

基本解释

The point of the experiment is that radioactive decay is a quantum process.
這項實騐的關鍵因素在於放射性衰變是一個量子過程。
But rather than test the radioactive decay using just one method, the researchers used three, involving the elements lead, samarium and neodymium.
但是，相對於僅使用一個方法測試放射性衰變，研究人員測定時使用了三種元素，鉛，釤，釹。
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”.
衹有重力和一種可以支配某些放射性衰變的弱核力能夠使其聚集凝固，“弱反應”這一術語由此得名。

Alpha particles are these helium nuclei, and they are the result of radioactive decay.
阿爾法粒子是氦核，它們是放射性衰變的産物。

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)
