拉曼光 [lā màn guāng]
Raman light
- 基于拉曼光时域反射计(ROTDR)技术,提出了冻土瞬态温度场的分布式光纤监测方法。
A monitoring method for transient temperature field of frozen soil using distributed optical fiber sensors was developed based on Raman optical time-domain reflectometry(ROTDR). - 光的拉曼散射效应对应地解释了离子声波的双峰结构、双峰强度不对称性及强峰出现的位置.
The two-peak strcture, the asymmetry and the position of the more intensity peak of the ion-acoustic waves can be well interpreted with the Raman scattering effect. - 本文还推导了幅度损耗腔中Ⅴ型三能级原子与光场拉曼相互作用系统的密度算符，并由此研究了系统、光场和原子线性熵的特性。
The results show that the linear entropy of the system and atom are larger than zero except the initial time in a dissipative cavity.
