NEPTUNIUM SERIES在英语中的意思是什么？

朽烂链

Decay chain

在核科学中，衰变链是指不同离散放射性衰变产物的放射性衰变作为一系列连锁的变换。 大多数放射性同位素不直接衰变到稳定状态，而是经历一系列衰变，直到达到稳定的同位素。 衰变阶段由它们与之前或后续阶段的关系来表示。 父母同位素是经历衰变以形成女儿同位素的同位素。 女儿同位素可能是稳定的，或者它可能衰变形成自己的女儿同位素。 女儿同位素的女儿有时被称为孙女同位素。 单个母体原子衰变到其母体同位素原子所需的时间可以广泛地变化，不仅对于不同的母体 - 子链，而且对于母体和子母同位素的相同配对也是如此。 当单个原子的衰变自发发生时，相同原子在时间t上的初始群体的衰减遵循衰减指数分布e-λt，其中λ被称为衰减常数。

In nuclear science, the decay chain refers to the radioactive decay of different discrete radioactive decay products as a chained series of transformations. Most radioactive isotopes do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached. Decay stages are referred to by their relationship to previous or subsequent stages. A parent isotope is one that undergoes decay to form a daughter isotope. The daughter isotope may be stable or it may decay to form a daughter isotope of its own. The daughter of a daughter isotope is sometimes called a granddaughter isotope. The time it takes for a single parent atom to decay to an atom of its daughter isotope can vary widely, not only for different parent-daughter chains, but also for identical pairings of parent and daughter isotopes. While the decay of a single atom occurs spontaneously, the decay of an initial population of identical atoms over time t, follows a decaying exponential distribution, e−λt, where λ is called a decay constant.
