characteristic virtue
1.In view of the characteristic of virtue reality system, a method based on the multimedia timer of Windows, OpenGL and high speed COM port is presented in this paper to realize fast data transmission and image display of DataGlove in real-time. By using this method, this paper gets satisfying effect in the application and provides a friendly interface to the user.
2.The virtue of multicast communi-cation in a LAN is analyzed,and the technical concept,the characteristic and the principle of the IP network multicast are elaborated.
3.Its virtue lies that it introduces the characteristic of connection mode into aconnectionless-oriented network and it can provide end-to-end service guarantees in both reliability and service quality to user.
4.By virtue of the stochastic bifurcation theory,the transition of the atom movement at a crack tip in fatigue damage system is investigated.Using the singular point theory of one-dimensional diffusion process and the stochastic averaging approach of energy envelope,a micro-model to describe the atom movement at the crack tip in homoclinic bifurcation fatigue damage system,which is in the presence of stochastic perturbation,is established.After the study on the characteristic of the diffusion exponent,the drift exponent and the character exponent of the fatigue damage diffusion process on singular boundary,the bifurcation behavior of a homoclinic bifurcation fatigue damage system,which is in the presence of parametric white noise,is examined.
