This paper gives the proof of this rule, and applies this rule to calculate the transition probability of the emission and absorption of light.

本文给出了这一规则的证明，并应用此规则计算了光的发射与吸收的跃迁几率。

The transparent adhesive must be homogeneous and low in absorption of light, and its refrangibility must be same as that of the material to be bonded.

作为光透性胶粘剂，必须均匀，对光具有低的吸收，和被粘接材料的折射率相当。

And that sparse array of wires has exactly the same light absorption and electricity-collection properties as the conventional silicon wafer cell."

Here, plastics that are black to the eye actually reflect a reasonable amount of light, so it is possible to get a meaningful absorption spectrum.

Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations.
