Chapter 8 is cast for the investigation of fractional revivals in an one-modeoptical field interacting with a Kerr medium.

第八章研究了单模光场与Kerr介质相互作用系统中的分数恢复。

Fractional revivals,however,are not exactlyhierarchical in amplitude;in other words,their amplitudes are not certain to de-crease with the increase of p,unless the signal mode is very strong.

然而，分数恢复的振幅并不是严格分级的。换言之，它们的振幅并不是一定随p的增加而减小，除非信号模很强。

By adopting the real-time rescaled range algorithm developed from the RS method, we do the simulation work using Fractional Gaussian noise and real network traffic data collected from LAN and WAN. It shows the method we bring up can differentiate normal network traffic and DDOS attack traffic effectively and precisely in most situation, and has provided a new way to detect and prevent DDOS attack duly and precisely.

Using linear accelerator,the dose rate of the 6MV X-ray was 2Gy/min.The A549 spheroids was not more sensitive to low doses of single radiation.After exposure to 2-8Gy radiation,the spheroids recured quickly.Thetreatment of fractional radiation were more effective than single ones.With the increase of radiation doses,the 〓-M% block increased,numberof dead and apoptosis cells increased.

直线加速器产生的6MV高能X射线，2Gy／min的剂量率照射，A549多细胞球体对低剂量单次放疗不太敏感，2-8Gy范围内低剂量放疗后球体细胞很快增殖复发，分割放疗疗效优于单次放疗。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
