这项技术包含拉曼散射，这种散射指反射光会因为原子或分子的激发而有一个波长上的移动。
These techniques include Raman scattering, in which light returns with a shift in wavelength as a result of atomic or molecular laser excitation.
就如大肠杆菌的移动，行为模块的激发建立在大脑中偶然性和规律性因素的相互作用的基础之上。
As with abacterium's locomotion, the activation of behavioural modules is basedon the interplay between chance and lawfulness in the brain.
通常，在光伏芯片中，被光子激发的电子，在导电材料内部电场的作用下，通过导线定向移动。
Normally, in a photovoltaic cell, electrons knocked free by photons are then carried away by an electric field within the photovoltaic material to a contact wire.
