本人原创精简方法，主要是完美解决精简后却发现安装出来的系统体积占用和原版一样，甚至有时比原版还大的问题。其中的工具及精简批处理，来自自由天空论坛，但本人对精简批处理作出了一系列修正，原来的精简批处理精简得太厉害了，以致于系统出了一些小问题。微软原版操作系统下载地址来自于网上，本人不负责任何技术支持，请谅解。

ChinaAbstract: BML model is a two-dimensional cellular automata model, which is especially used to simulateand analy ze the traffic system. We use Java language to implement this model. With this model, the re-ationship between the average velocity and the average density has been found by computer simulationThe phase transition and self organization have also been faund. And at last, the bml model improved intraffic light cycle changes for exploring more valuable to the research and applicationKey words: two-dimensional cellular automation; traffic flow; BML modelC1994-2013CHinaAcademicJOurnalElectronicPublishingHouse.Allrightsreservedhttp://www.cnki.net
