As the most of traditional Intrusion Detection Systems are static and have difficulty in coordinating with the outer dynamic situation, consequently, leading to a serial of deficiency such as limited distribution .limited accommodation and limited robust etc. Fortunately, the Human Immune System can protect themselves from the invasion of the virus, germina and all such sort of things. Meanwhile, they has a lot of excellent features such as good distribution, Self-organization,dynamic and so on and these features perform fabulous similarity on the function and characteristic with the Intrusion Detection System,which arousing peoples highly attention and interesting and make the researching and development of the Intrusion Detection System based Human Immune System becoming one of the hot and the key of the network security research.

By carrying out ~1H spin-diffusion experiments,the domain sizes of DNA in the complexes were determined.The domain size of DNA is found to decrease greatly when the N/P ratio changes from 0.5 to 3 and changes only slightly with further increase of the N/P ratio.After making a thorough analysis and discussion on drug control release and gene delivery systems with general NMR techniques,we presents a method of 1D PFG NMR technique to realize quick observation on the Mw change of polymer during its degradation process.Moreover,according to the inverse Laplace transformation theory and based on a function of diffusivity distribution of polymer in solution,2D PFG NMR technique is developed to measure the Mw distribution of polymer.Combined with Monte Carlo simulation,the degradation mechanism can be figured out.
