In the meantime, we also can change the status of the logic situations and describe the allying process and cooperative process. In addition, we represent the virtual enterprise ontology in the formal logic situation calculus and can define the core elements more accurately. It maintains the consistency and integrality of the ontology. Accordingly, the process model based on the ontology will have strong reusability, accessibility and consistency.

相应地，我们可通过逻辑情景演算这种形式化逻辑框架来表示虚拟企业本体论，以支持虚拟企业本体论中核心术语的更精确定义，维持其一致性和完整性；进而，构建于该本体论之上的虚拟企业过程模型就具有很强的重用性和可访问性，并能够保持建模过程的一致性。

The above three soybean varieties were treated with short-day of 12 h and long-day of 16 h in whole growth period, the different photoperiod treatments changed development process, podding-habits, plant morphogeny, and agronomical characters of different types of stem termination. And by this method photoperiod-sensitive and photoperiod-insensitive soybeans were divided, which is an important meaning at the production and popularization of soybean varieties.

对以上三个不同结荚习性品种进行两种较为极端的全生育期光照处理，短日照处理(12小时)和长日照处理(16小时)均可不同程度地影响不同茎顶类型品种的生育进程、结荚习性、株型和其他农艺性状，并且以此方法可区分出光敏感性相对较强和较弱的品种，对品种的生产和推广有一定的指导意义。

Race of powerful southwest field, low altitude, to Yingdede area in a steady stream offerred enough lunt; ceaselessly close ground layer is in low chamfer brim, force is not steady energy grow in quantity, the generation that is durative strong precipitation was offerred spark enoughly mechanism.

Ant Colony Algorithm is a new developed bionic optimization algorithm, which simulate the ants'finding food process. Because of its simple mechanism, plus-feedback parallelization, strong lustiness and excellent distributed compu- tational mechanism, it has shown its excellent capability and huge developing potential in solving many complicated optimization problems, and it has been successfully applied to production problem such as scheduling problems and routing problems. But it also has some disadvantages, it need longer searching time than others and tend to precocity and stagnation.

To solve this problem, based on the concept of graph theory we give a few models and arithmetic designs of virtual backbone in the environment of different application, and propose the corresponding routing mechanism with these virtual backbones. The major achievements are outlined as follows:The state of host's power or the time of host's online plays an important role in keeping stability of a virtual backbone. With a view to this feature, the paper introduces a simple and efficient heuristic algorithm for calculating the virtual backbone by seeking a minimum connected dominating set with maximal weight. The maximality of the weight-based choice of backbone nodes guarantees that the most suitable nodes have been chosen for the role of backbone nodes so that they can properly coordinate all the other nodes and keep stability of the virtual backbone in the network.

为了解决这个问题，本文利用网络图论中的一些理论，在不同的应用环境下给出几种虚拟骨干网的模型、构建及基于稳定性和节能的算法设计，并针对这些骨干网提出相应的分层路由机制，主要研究内容和贡献如下：考虑到主机的功率大小和在线时间长短对虚拟骨干中心的相对稳固性的影响，提出用基于极大权的最小连通支配集模拟虚拟骨干网；并给出其数学模型和相应的启发式算法，确保了性能强的主机担任骨干节点；通过优化规则确保骨干网的极小性，有效地减小了控制分组转发开销；最后进行了仿真验证。
