有界链

Following the definition of graph topology and network routing, a bounded neighbor discovery algorithm is proposed, and the upper bound on trips of any loop crossing one specified links is proved. A path generation algorithm based on the neighbor/path matrix is also presented and validated by some examples.

文中首先给出网络和路由的定义和表示；再提出基于有界扩散的邻接发现算法，并证明某一回路穿越特定链路次数的上界；然后提出基于邻接矩阵的路径生成算法，并给出实例分析以验证上述算法的正确性。

With a suitable performance function and an initial control that made the closed system bounded, a serial of controls that made the performances better could be obtained by policy iteration, and ergodic Markov chains were constructed by the state serial with the corresponding feedback control.

在合适的性能指标并能找到一个使系统性能有界的控制的前提下，通过策略迭代可以求出逐步改善系统性能的控制序列，同时得到状态序列在相应反馈控制作用下构成遍历的马尔可夫链。

Concerning this problem, we put forward a kind of Stochastic Colored Petri Net, analyzed the limitary and reachable, and proved that SCPN is same as a continuous time Markov chain.

分析了它的有界性和可达性，证明了它同构于一个一维连续时间的马尔可夫链；同时，也分析了随机着色Petri网用于建模和系统性能定量分析的方法。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
