line-connectivity meaning in Chinese

线连通度边连通度

Most notably , the parameters called connectivity and line - connectivity have been frequently used . the connectivity of a graph g is the least number of vertices of g whose removal disconnects g similarly , the line - connectivity of g is the least number of g whose removal disconnects g the higher the connectivity ( edge - connectivity ) of g , the more stable it is considered to be
而这些研究工作主要是围绕点连通度，边连通度，局部点、边连通度来做的，但随着图的连通性研究的不断深入，人们越来越觉得仅用点连通度，边连通度，局部点、边连通度来描述图的连通性存在很大的局限性。
For the two sides above , it is urgent for us to find new parameters to measure the stability of graphs . consequently , a number of other parameters have recently been introduced in an attempt to cope with the difficulty which the connectivity and line - connectivity have , including toughness , edge - toughness , tenacity , edge - tenacity , scattering number and integrity
正因如此，在图的连通性研究中，迫切需要一个既能反映系统被破坏的难易程度又能反映系统遭受破坏程度的参数，而图的完整度正是符合这样要求的一个参数。
