查询词典 rational fractional function

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.

In the following, we quantize the supersymmetric anyon system according to the rule of path integral quantization for constrained Hamiltonian system in Faddeev-Senjanovic scheme. We calculate the quantal conserved angular momentum based on the quantal canonical Noether theorem, and present the fractional spin property at the quantum level.
