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。

With this method, the nextto-leading order Debye screening mass was evaluated within real time hot QCD. Since the gluon damping rate was included self-consistently on the internal line of the self-energy, the infrared divergences were removed without putting by hand in a nonperturbative magnetic mass as a cutoff, and the results are positive and gauge-independent. In addition, the selfconsistent calculation method of the damping rates of the fast moving particles in a QGP was suggested, the self-consitent equations were derived at finite tempeature without infrared divergences, and the approximation solutions were shown. Meanwhile the relaxation times of the gluons and quarks were estimated as τ〓~0.7fm/c and τ〓~1.5fm/c at energy scales of RHIC and LHC.
用这种自洽方法从实时热QCD出发用计算了QGP中次带头阶Debye屏蔽质量,由于自洽包含了胶子自能内线中横胶子的衰减率,克服了红外发散的困难,不必用手加的非微扰磁质量作截断,证明了得到的结果是正定的且规范无关,同时本文给出了QGP中快速粒子衰减率的自洽计算方法,推出了有限温度下快速粒子衰减率的自治方程且红外发散不出现,给出了方程的近似解,并估计了RHIC和LHC能标下胶子和夸克的弛豫时间分别为τ〓~0.7fm/c,τ〓~1.5fm/c。

Towns like Bournemouth and Eastbourne sprang up to house large "comfortable" classes who had retired on their incomes, and who had no relation to the rest of the community except that of drawing dividends and occasionally attending a shareholders meeting to dictate their orders to the management.
有限责任公司的增长和公共商业的发展已经带来严重的后果,如此巨大的个人操作的资本和工业极大地增加了持股者作为一个阶级的数量和重要性。国家生活里出现了一种和土地责任相分离的不负责任就有财富的人,而且几乎也没有进行商业管理的义务。
