系统树

The result was basically consistent with three methods which was NJ, ME, UPGMA constructed in molecular phylogenetic tree, the gayal was clustered together with cow firstly, chimpanzee, rhesus monkey and human clustered together, then together with each other, followed by other species.

用NJ、ME和UPGMA等3种方法聚类构建的分子系统进化树表明，3种方法的聚类结果基本一致，即大额牛与普通牛首先聚为一类，人、黑猩猩、恒河猴也先聚为一类，这两类相聚后再依次同其他物种聚在一起。

The paper says, in order to deal with the challenges of knowledge economy and economy globalization, as well as to re-set up public confidence in accounting profession, we need to step up accounting management reform and innovation as follows on one hand: use international experience for reference to accelerate the process of accounting internationalization, and reduce chances of providing false account; carry out outside and inside supervision at the same time, that is, improve corporate governance and internal control system, deal with "insider control problem" from inside of the system, and fundamentally resolve the problem of corporate accounting falsification; intensify government supervision and profession self-discipline from the outside, and strengthen punishment; set up civil litigation and civil compensation system, especially to run corporation deputy's liability so as to make false account provider get more kicks than halfpence, and restrain or eliminate falsifying impulse.

分析认为，为迎接知识经济与经济全球化的挑战，重树社会公众对会计业的信心，我国一方面急需加快会计管理的改革：借鉴国际经验，加快会计国际化进程，压缩会计造假的空间；实行内外监管并举，即在内完善司治理结构、建立健全内部控制制度，从系统内部解决"内部人控制问题"，以从根源上治理财务造假等问题，在外加强政府监管与行业自律并举，加大惩处力度，建立民事诉讼和民事赔偿制度，尤其是加大对公司法人代表的责任追究力度，以使蓄意提供虚假会计信息变得得不偿失，从而抑制或消除其造假的冲动。

Second, we research harmonization and collaboration in MRS and carry out collaboration model based on tree/map.

In molecular phylogebetic tree constructed, we made the Ka / Ks value pairwise comparison of HMGbox flanking sequences both intra- and inter- Hominoid and the Old World m onkey .

通过构建系统发育树，比较旧大陆猴和人猿超科两个类群内和类群间HMG盒侧翼序列K a/Ks的比率。

ID〓 is characterized by the fast speed of training and classifying, and it can be applied to large-scaled learning problems. But the selection criterion of attribute is the core of ID〓, and is now doubted. AQ〓 is a type of decision rule induction, presented by Michalski, a scientist of U. S.. It is characterized by high-precision classifying and capability of knowledge expression, and it can be applied to automatic knowledge acquisition in expert system. However, the inducing and matching speed of AQ〓 is slow.

其中决策树归纳以澳大利亚学者Quinlan的ID〓为代表，其特点是训练与分类速度都很快，适用于大规模的学习问题，但ID〓把注意力集中在属性的选择标准上，然而这种思想方法已开始受到人们的怀疑；决策规则归纳以美国学者Michalski的AQ〓为代表，其特点是分类精度高和知识表达能力强，适用于专家系统的知识自动获取，但归纳和匹配速度都慢。
