In chapter four, we study the second isoperimetric connectivity of line graphs and line digraphs. For line digraphs, we show that the second isoperimetric connectivity of strongly connected line digraphs with δ≥ 2 equals its connectivity. For line graphs, we give a sufficient and necessary condition for the existence of the second isoperimetric connectivity, and we show that under the condition that the second isoperimetric connectivity exists, the second isoperimetric con

Based on maximum likelihood estimate, the estimate method of sieving rate of connectivity sieve was presented. Three key issues in the estimate were analyzed:calculation of sample size,generation of random sample, and recognition of connectivity of induced subgraph. By preassigned credibility and precision, effective estimate of sieving rate of connectivity sieve is achieved.

目前，产品拆卸过程规划基本上是建立在图的基础上，即首先根据产品拆卸回收或拆卸维修信息，选用一种适合的图模型进行描述，然后在图模型的基础上，以拆卸回收或拆卸维修的经济性、环境协调性和技术性等综合指标最优为目标，进行拆卸过程规划，最终得到产品的最优拆卸序列【1一。1连通性筛子拆卸与或图是拆卸模型中的一种，文献[7]给出了拆卸与或图的定义及建模过程。

Comparing the landscape types of 1995 with that of 2005, we find out that:①the natural arbors are decreasing, with patches more fragmentation, size more odds, shapes more complex;②the area of natural shrubberies is increasing, with patches less fragmentation, shapes more simple and formulary ,the size of patches more even;③the area of natural grasses is increasing, with patches less fragmentation, shapes of patches more odds;④the area of timbers is increasing, with patches more dominance in landscape, more connectivity;⑤the area of Eucalyptus increases, with patches less fragmentation, shapes of patches more complex , more convergence, more connectivity;⑥the area of orchards is increasing, more connectivity;⑦the patches of the rubber is becoming more assemble, more connectivity, more formulary;⑧the area of plowland increases;⑨the area of reservoirs, rivers and ponds increases, with patches more assemble;⑩the area of cities decreases, with patches more dispersing, with shape more complexthe area of countries increases, with patches less connectivity, more dispersing, with shape more complex; the patches of the rest lands are more dispersing, with shape more complex;(3)In the process of economic development in the upper reaches of the Changhuajiang river watershed, a series of the ecological environment problems have appeared because a lot of landscape function broke off, and the connection of human landscape with natural landscape decreased, which aroused by the fragmentation of natural and semi-nature landscapes increased, the stability of the landscape structure decreased, as well as stress of human disturbance, resource and environment upon the landscape increased gradually.

3昌化江上游流域在经济发展进程中，自然与半自然景观破碎度增加，自然景观结构稳定性下降，人为干扰、资源和环境对景观胁迫逐渐增大，中断了许多生态过程，导致城市等人文景观与自然景观连接度很差，产生了一系列的生态环境问题。

In this project, we propose a novel 3D morphing technique that avoids creating a merged embedding that contains the faces, edges and vertices of two given embeddings. This novel 3D morphing technique dynamically adds or removes vertices to gradually transform the connectivity of 3D polyhedrons from a source model into a target model and simultaneously creates the intermediate shapes.
