allowed transition造句

• Quantum interference occurs in a three - level a system with near - degenerate dipole allowed transitions , which are coupled to the same linearly polarized incoherent field
  如，当a型的两个跃迁与一个线性极化的非相干场进行耦合时，非相干泵浦产生量子干涉。
• 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。
