The fine structure constant, and other fundamental constants, are absolutely central to our current theory of physics.

微细构造常数和其他基本常数都无疑是我们现在研究的核心。

The researchers found that in the northern sky, the fine-structure constant gets smaller with increasing distance, or as astronomers look farther back in time.

研究人员发现在北方天穹，精细结构常数在越远的地方就越小，或者说天文学家所看到的过去越久远。

Slightly belying its name, the fine-structure constant is actually a compound of several other physical constants, whose values can found in any physics textbook.

精细结构常数实际上是其他几个能在任何物理学教科书中找到数值的物理常数合成，同它的名称稍微有些名不副实。
