Phenomenal analysis of fine structure constant 發(fā)生改變的唯象分析
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 能階是由原子核拉住電子的松緊程度所決定,而這又取決于能階之間的電磁力強(qiáng)度,因此便和精細(xì)結(jié)構(gòu)常數(shù)關(guān)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 這項(xiàng)發(fā)現(xiàn)為近來(lái)一項(xiàng)引人爭(zhēng)議的觀察做了補(bǔ)充:用來(lái)描述電磁力總體強(qiáng)度的精細(xì)結(jié)構(gòu)常數(shù),已經(jīng)些微增加了。詳情請(qǐng)見4月21日的《物理評(píng)論通訊》 。
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 摘要本文介紹原子物理學(xué)中重要的無(wú)量綱常數(shù)之一的精細(xì)結(jié)構(gòu)常數(shù)的由來(lái),討論它的物理意義和理論計(jì)算。
