Also in the 3-D space, we assign the 20 amino acids to 20 vertices of the dodecahedron. By the symmetry of the dodecahedron we obtain 3-D representation of 20 amino acids, and 3-D graphical representation and the corresponding numerical sequence of protein sequences. And similarity and dissimilarity analysis based on the invariants of graphs and characteristics of numerical sequences are given for nine RNA secondary structures of RNA-3 of virus. We construct sequence phylogenetic tree of a group of cytochromes C protein.

在DNA三联体密码子表示的基础上，在半复平面上给出了蛋白质序列的非退化的2-D图形表示，同时利用复向量的主要特征—模和相位，给出了蛋白质序列的一种数值刻划，进一步在3-D空间里，把20种氨基酸分别分配给正12面体的20个顶点，根据正12面体的对称性得到了20种氨基酸的3-D表示，进而得到了蛋白质序列的3-D图形表示和对应的数字序列，并利用图的不变量和数字序列的特征比较了9种动物的神经元

Some necessary conditions are obtained for sequential graphs, regular sequential graphs and Euler sequential graphs; several non-sequential graphs classes are showed for conglutinating graphs. The sequential graphs that contain even cycle with the same vertices have been constructed.

使用这种方法，得到了一般序列图、正则序列图、Euler序列图、圈的粘接序列图和圈的并序列图的必要条件，证明了边数为2k， k是奇数的Euler图是非序列图类，讨论了m个n圈的粘接图中的非序列图类；分析偶圈的特征，构造了偶圈的具有同顶点集的序列母图井给出其序列标号表达式。

According to the regulations above, the paper presents the virtual price and profit function in the course of selecting cars for the departing trains and the model of the grouping cars into arrival trains.

在车流推算的基础上，从应用计算机模拟区段站调度员思维的角度出发，通过分析车列占用调车机车时区集合的特点，使用划分时间片的方法建立合适的调车机车安排的图论模型，将调机运用问题转化为顶点具有加权的图的K-着色问题。

Based on analyzing the algorithms of Delaunay triangulation creation in domestic and abroad, in view of the situation of building DTM and the need of realizing railway 3D visual design, a divide-and-conquer algorithm to build DTM is presented, the algorithm use square grids to manage disordered points, to form triangular meshes in grids, DTM can be obtained by merging the triangular meshes, so that the work of sorting of the disordered points before building DTM is reduced greatly; moreover, the algorithm utilize subarea to control the vertices of convex hull so that the range which support points locate in can be predefined when searching support points, the workload of searching support points can be reduced and the speed of merging two triangulations is raised.

在分析了国内外构建DTM算法的基础上，针对DTM算法的现状及铁路线路三维可视化设计的需要，创立了一种构建DTM的分治算法。算法引入方格网管理离散点数据，在格中构建三角网，然后再将这些三角网合并形成DTM，极大地减少了构网前对所有参加构网的离散点进行排序的工作量。此外，通过对凸包顶点数据进行分区管理，在搜寻凸包支撑线时，能预先确定出支撑点的范围，减少了搜索工作量，提高了三角网的合并速度。
