精细结构常数 meaning in Chinese
fine structure constant
fine-structure constant
Examples
- These energy levels are determined by how tightly the atomic nucleus holds the electrons , which depends on the strength of the electromagnetic force between them ? and therefore on the fine - structure constant
能阶是由原子核拉住电子的松紧程度所决定，而这又取决于能阶之间的电磁力强度，因此便和精细结构常数关系密切。 - These findings complement recent contentious observations that the fine - structure constant , which describes the overall strength of the electromagnetic force , has increased slightly
这项发现为近来一项引人争议的观察做了补充：用来描述电磁力总体强度的精细结构常数，已经些微增加了。详情请见4月21日的《物理评论通讯》 。 - The fine - structure constant is an important zero dimension constant in the atomic physics . this article introduces the origin of fine - structure constant , and discusses its physical significance , and theoretical calculation
摘要本文介绍原子物理学中重要的无量纲常数之一的精细结构常数的由来，讨论它的物理意义和理论计算。
