This article introduces the reason why there s existing the distortions of the micro align models and explains what is cross distortion and scan distortion 340 and how to match the different "340".

Through adopting the dot-sample method and VISSIM simulation technics,this paper made delay calculations and analysis to a deformity intersection in the old city zone of Hefei , and vadilate the simulation accuracy based on VISSIM.

The theory of common intersection channelization has been rather mature, but the the- ory of deformity intersection channelization is short of systematicness.

In aircraft electric power system,electric power source is the key device for aircraft s performance,the quality of electric supply directly effects various utilization equipment in aircraft,so it must meet the requirements of GJB 181A,the most important standard is AC distortion spectrum and AC distortion factor.

This paper studies a continual-domain ant colony algorithm based on the overlapping mutation operation, which forms a dynamic candidate group to the solution of each component possible value, and records each possibility value information content in the candidate group.
