电偶极跃迁 meaning in English

electric dipole transition

The significant feature of the system model is that the two - dipole moment is in the v configuration . of the two dipole allowed transitions , one is very strong while the other is very weak
系统模型的特征是，三能级系统中电偶极跃迁构成v型结构，其中一个跃迁很强，另一个跃迁很弱。
One typical model for cpt is the a type three - level system when the life times of the ground levels are long enough and the coherent driven transitions are on the two - photon resonance
一类典型的系统是电偶极跃迁构成a型的系统，条件是两低能级寿命很长， a型两偶极跃迁发生双光子共振。
First , we study electromagnetically induced absorption . this significant feature of the system model is that a four - level system in which three - dipole transitions are in n configuration in this system , the middle transition serves as a probe transition and two other transitions serve as couple transitions
系统的模型特征是：三个电偶极跃迁构成n型链的四能级系统，其中，中间跃迁为探测跃迁，两边的跃迁为耦合跃迁。
