简介：一张图的一个顶点被说统治它的邻居的本身和所有。图G的一个双统治集合是G的顶点的集合D，以便G的每个顶点被D的至少二个顶点统治。图G的双支配数字是G的一个双统治集合的最小的集的势。为图G=(V，E)，如果V(G)\D的每个顶点在D有至少二位邻居，子集DV(G)是一个2-dominating集合，当如果，统治G的集合是2-outer-independent的时另外集合V(G)\D是独立的。G的2-outer-independent支配数字是统治G的集合的2-outer-independent的最小的集的势。这份报纸加一个与双支配数字平等者描绘所有树到2-outer-independent支配数字。

简介：一部新款奔驰S280更换发动机控制模块后,使用STAR2000编程巡航功能不起作用,读取发动机和巡航控制系统故障码,没有故障码.我们所使用的编程方法是,读取旧控制模块上的程序,再写到新控制模块上.按编程方法应该没错,为什么巡航功能被取消呢?带着这一问题,我们一起学习奔驰编程新方法,FlashingandSoftwareCaiibrationNumber(SCN)闪存和软件校正码.
