For the first time, the dynamics changing process of KGM chain in vacuum is proposed, We obtained the following results: polymerization degree influences the stability and shapes of the chain, the chain stability drops with the increasing of polymerization degree, for the high polymerization degree KGM, KGM chain takes on irregular curl state; acetyl group is not the main factor influencing chain conformation , during the course of dynamics movement KGM chain takes on irregular curl state before and after acetyl group was doffed, Extending and curling states change periodicity and has good flexibility.

LDoS (low-rate denial-of-service) attacks are stealthier and trickier than the traditional DDoS attacks. According to the characteristic of periodicity and short burst in LDoS flows, a detectionsystem DSBWA (detection system based on wavelet analysis) against LDoS attacks has been designed andimplemented based on feature extraction using wavelet transform.

The following exciting results are revealed: 1 When considering the influence of some nonlinear elements such as hard-limit of exciters, the effects of some devices such as Power System Stabilizer and Static Var Compensator which can introduce positive damping in power system, the reasonability of system parameter values in simulation, the SNB surface and HB surface on the boundary of SSSR will turn close to each other and even coalesce together; 2 Under some conditions, coupling between slow exciters and shunt capacitors will bring negative damping in power system dynamics, which increases the possibility of oscillatory instability. So the power system with mass shunt compensators is easily subjected to the oscillatory instability. In recent years, chaotic phenomena of power system have been reported many times. Some simulation studies even found chaos existing inside the power system SSSR. In this dissertation, chaotic phenomena in power systems are thoroughly studied in order to make clear the relation of chaos and SSSR. The following results are derived: 1 Based on Li-Yorke Theorem and their definition on the chaos, the existence of chaos in power system is verified; 2 Three possible routes of causing chaos in power system are found and deeply investigated. They are route of cascading period doubling, route of directly initial energizing and route of torus bifurcation (or quasi-periodicity). The latter two routes are investigated for the first time in power system stability studies; 3 When the stability conditions of chaos are broken, it is found they can lead to voltage collapse, angle divergence, or voltage collapse with angle divergence simultaneously.
