The experimental results and theoretical analysis show that the predicted value of interfacial bond strength of old-new concrete is more precise when the roughness of old concrete fracture surface is characterized with fractional dimension D.

利用自行研制的分维仪对试验后的老混凝土断裂面进行测试，并应用分形几何这一理论工具对测试结果进行分析，得到了老混凝土断裂面的分数维与新－老混凝土界面粘结强度的关系。

In conclusion,KPAS and fractional revivals belong to two new kinds of non-classical effects.

第二部分探讨的是分数恢复现象。

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.
