查询词典 pumping

One of the critical point for solving this problem is to effectively identify the pumping mechanisms of known OH masers and find out the physical connections between the masers and the objects bearing these masers.

解决这个问题的关键之一就是在已知的OH脉泽源中有效地鉴别出它们的脉泽抽运机制，并由此找出脉泽特征与产生脉泽的天体之间的物理联系。

The bright OH masers are excellent probes of different kinds of astronomical objects in the Galaxy and even of distant galaxies, but the difficulties in identifying the pumping mechanisms of these OH masers and modeling them have hindered the application of this excellent probe.

明亮的OH脉泽是探测银河系中各类天体甚至河外星系的极好工具，但是对OH脉泽的抽运机制的鉴别和模拟上的困难使得这个极好工具一直没有得到极好的发挥。

Based on the theoretical model coupling Maxwells equation with the rate equation of 4 level inverted population, the numerical simulation is made via the FDTD method and MATLAB programs. The simulation results show that 1. With the increase of the pumping rate, both the localization of the electric field and the spectrum mode numbers will change; 2. The lasing threshold decreases by increasing the size or concentration of the scatters; 3. The lasing threshold also decreases by increasing the size of samples or strengthening the sample randomness.

在理论和实验研究的基础上，利用麦克斯韦方程与四能级反转粒子数的速率方程相耦合的理论模型，采用时域有限差分方法和MATLAB程序对随机激光泵浦阈值特性进行了数值模拟与计算，模拟结果显示：随着泵浦速率的增大，出现了阈值前后电场强度局域态及频谱模式数的改变；随着散射体粒径的增大，浓度的增大，阈值呈现下降的趋势；随着样品长度的增大，随机强度的增强，阈值也呈现下降的趋势。
