例句
- The molecular extinction coefficient is equal to the ratio of the log of the intensity of the incident and emergent light.
分子的消光系數等于入射光和透射光強度對數的比。 - At zero intensity, the last glimmer of the light vanishes into the atoms, and the polariton comes to a dead stop.
到了控制光強度歸零之時(shí)，光的最后一絲光芒都消逝到原子里，極化聲子就完全停止了。
