The analysis show that O-forming is accomplished by bending of subdividing suspend arc,characterized by evolvement of curvature peaks form one to multiple peaks,which have nearly equal peak-to-peak distance.Process loading has corresponding episodic changes,and each episodic curve is similar.Loa...

Previous solutions to these problems, such as topology conversion methods and forward-pointed arcs methods, not only have deficiencies of having high temporal and spatial complicacies, but also have shortcomings for the topological data difficult to be formed and be renewed in good time. This paper comes up with an Arc Topology Algorithm to solve one-way road prohibitions and turn penalties problems, and puts forth Azimuth Algorithm and Turn-angle Algorithm to solve nodal weight problem.

针对以往的解决方案如转换网络法和扩展的前向关联边法计算的时间复杂度和空间复杂度高以及拓扑数据难以建立和难以实时更新的缺陷，论文构造了弧段拓扑法以解决单向行驶限制和转向限制问题，构造了方位角法和转向角法以解决节点权重问题。

As a result,the OmpK genes not only were distributed widely in all tested Vibrios,but also shared quite high similarity in nucleotide sequences and deduced amino acid sequences.

序列分析还表明，每一种弧菌OmpK基因都有一段特异性序列，可用于设计核酸探针或特异性引物来诊断、检测哈维氏弧菌等海水鱼致病性弧菌。

The experiment of the auxiliary heated arc plasma generator shows that thekey arc root has contraction under the condition of having magnetic field when thekey arc root is at the edge of the cathode surface.

在辅助加热电弧等离子体发生器的实验中看到：在有外磁场的情况下，主弧弧根在阴极边缘时，弧根有收缩的迹象，而当主弧弧根在阴极中心附近时，观察不到明显的弧根收缩迹象，并拍摄到有双弧柱的图片；当关掉磁场和弧电流〓时，主弧在阴极和阳极之间稳定的燃烧，主弧弧根稳定在阴极中心附近的一点上，而且弧根没有收缩的迹象，主弧弧根亮区的直径约为6.8毫米，与弧柱段的亮区直径相差无几；因而从实验结果分析可以看出，阴极表面温度的升高，能使主弧弧根直径增大：另一方面，由于主弧弧根直径的增大(即也意味着主弧弧根截面积的增大)，因而使电弧通过主弧弧根传入阴极表面的有效比热流降低，从而减少了阴极烧损。

In order to get out from the cockamamie work in road route design for designers, on the basis of studying the internal relations among local schemes, local scheme was decomposed to small unit logic schemes; the directed network was used to represent the topological connection; the united data structure of point-arc was used to express a network graph. Based on the shortest path theory, the combinatorial optimization algorithm that can search optimal logical schemes of some targets in the network graph intelligently and can form the whole scheme automatically was put forward.

为了使设计者从道路线路设计的繁重计算统计工作中解脱出来，在研究了局部方案间内在关联的基础上，提出了将局部方案分解为更小单位的逻辑方案，用有向网络图表示逻辑方案间的拓扑关系，采用节点－弧段联合数据结构来表示网络图；同时基于最短路径理论，提出了在网络图中智能化搜索综合指标最优的逻辑方案集，自动形成整体方案的组合优化算法。
