连通链

Introduced a line detection method that is simply connected to the chain, its definition of simple and clear physical significance, easy storage and handling.

采用了一种检测直线的方法，即有向单单连通链法，它定义简单，物理意义明确，易于存储和处理。

Based on rooted connected directed graph both cyclic and acyclic, OIM can describe the relationship of a complex object and its component objects, as well as the links between HTML files in World-Wide-Web naturally.

它基于带根连通有向图，图中可出现环路，因而能自然地描述复杂对象与其成员对象间的引用关系和WWW上HTML文件间的链接关系。

By using the algebraic method, we obtain a new formula for the expected hitting time of random walks on strong-connected and aperiodic digrahs (irreducible and aperiodic Markov chain). From this formula, we obtain the explicit expressions for the expected hitting times of random walks on directed de Bruijn graph, directed Kautz graph and some graphs constructed from strong regular graph, etc.

利用代数方法给出了强连通非周期有向图上随机游动（即不可约非周期马尔可夫链）平均首达时间一个新的表达式，并利用这个表达式得到了有向de Bruijn图，有向Kautz图以及和强正则图相关的几类图上随机游动任意两点之间的平均首达时间。

The four sets of stator bars including those retired from three large generators and the standby bar subjected to Dynamic Mechanical Analysis, Scanning Electron Microscopic and optical microscope observation. It was revealed from DMA that the peak value tan d m of mechanical loss thermogram tan d ~ T shift toward a higher temperature and a lower amplitude, indicating that the amount of movement monomers diminished greatly in the insulation aging process, the tan d 195, increased very slightly with the service time of insulation, showing the degrading of bonding properties at interface, and the presence of more defects in insulation. The observation of SEM and optical microscope showed that more and more voids appears in insulation, and delamination was formed due to development of voids in aging process.

对不同运行年数的线棒进行了 DMA 、 SEM 、光学显微镜等微观分析试验，动态力学分析发现(参见 Hao et al， CEIDP， 2002：404)，力学损耗温度谱 tan d ~ T 的峰值 tan d m 随老化时间向高温、低值方向移动，表明促成环氧发生玻璃化转变的活性侧基或发生局部运动的活性链段减少，分子链的刚性增强；195℃的力学损耗 tan d 195随老化时间有缓慢增大的趋势，表明有更多的能量耗散在界面处，界面的粘合性变差，甚至由于界面粘结不良出现微观缺陷； SEM 和光学显微分析发现(参见 Hao et al-2， IEEE DEI， 2003)，老化后的绝缘气隙增多，随着老化时间气隙不断扩展或相互连通，绝缘逐渐分层。

Result shows that ground antiaircraft information chain after optimizing is superior to before optimizing from equally transmitting rate and feeding through probability.

结果表明，优化后的地面防空信息链在平均传输率和连通概率方面均优于优化前的地面防空信息链。

Equally transmitting rate and feeding through probability are regarded as an important index of ground antiaircraft information chain transmit ability, mathematics model is set up to contrast and analyse the transmission ability of ground antiaircraft information chain before and after optimizing.

将平均传输率和连通概率作为评价地面防空信息链传输能力的重要指标，建立数学模型对比分析了优化前后的地面防空信息链的传输能力。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
