In the feature information matching, this paper introduces a real-time monitoring model based on the finite-automatic machine multi-mode matching algorithm. The algorithm can directly compare the IP packet's content with the feature, and it solves the miscarriage of justice to the feature information.

在特征信息匹配方面，本文提出了一种基于有限自动机多模匹配算法的实时监控模型，可直接对IP数据包内容进行特征匹配，同时解决了由此而产生的特征信息误判问题。

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。

In order to verify the accuracy of the modeling built by ANSYS and the precision of the analytical results, the modelings of both rotor and motor are experimented at same time. After the comparisons of the numeric analysis results, experimental values are the foundation to consider the physical meanings and to suitably modify the modeling in order to decrease the differences between both results, to obtain the correct modeling type, to increase the analysis accuracy, and to provide designers a reliable basis.
