On the basis of the characteristic of initiative lane change in the realistic traffic flow,a new traffic flow cellular automata model that dealt with the initiative lane change of fast and slow vehicles differently was introduced based on symmetric two-lane cellular automata(STCA) model.

Aimed at slow system response, poor interaction and other problems of current desktop Linux in supporting application programs, the physical memory managing algorithm with active swap mechanism and preloading DLL algorithm based on heuristic study are proposed to shorten the system response time and enhance system interaction capability.

The result show that the ball teams could pay attention to use the index sign of substitution biggest limit,basic all active substitutions were proceed in the second half time,consider primarily of is to take the attacking game adjustment when active substitution was proceed and the military tactics result of active substitution was affected by own background directly.

This paper proposed an initiative handover method of a destination BS of IEEE 802.

【Objective】 To summarize the experience in anesthetic management for one-stage total thoracoabdominal aorta replacement with four branch vessel prosthesis under deep hypothermic cardiopulmonary bypass and subsection circulatory arrest.
