The principle of this method lies in that the importance of network nodes is not only related to the degree of the nodes themselves, but also related to the degrees of their neighborhood nodes and node betweenness.

其主要原则是网络中节点的重要性不但与节点本身的度具有一定的关系，而且与节点的邻居节点的度大小，节点的介数也存在一定的关联。

In order to fully consider the topology relationship between anchor nodes and between anchor nodes and unknown nodes, we introduce the concept of collinearity and apply it into the localization of the multihop networks, and a Collinearity-Based Localization Algorithm is proposed.

为了充分考虑锚节点之间以及锚节点与未知节点之间拓扑关系对无线传感器网络定位精度的影响，我们引入了共线度的概念并将其应用到多跳网络的节点定位中，在此基础上提出了一种基于共线度的无线传感器网络定位算法。

Based on considering the energy of nodes, the paper gives three attribute chatacteristics: flow factor、bridging factor 、convergence factor,and two ways to find articulation nodes:using energy model to find and finding key nodes in the connected gragh. At the same time,we use network simulator NS2 to simulate and verify our analysis results.

本文从考虑节点能量的角度出发，给出了关键节点的三个属性特征：流量因子、桥接因子、汇聚因子和两种判断关键节点的方式：利用能量模型判断和在连通图中判定关节点，同时用网络模拟器NS2加以模拟验证。

In this thesis, we propose a self-detecting algorithm for the nodes of a wireless sensor network to determine the event boundary in the presence of faulty nodes. The nodes exchange messages and execute the algorithm in parallel to determine whether they are located on the boundary of an event.

在这篇论文中，主要的目的是在一个无线感测网路环境下，如果当事件发生时，每一个感测节点如何透过单纯的资料交换和平行演算法来达到自我侦测并且判断出本身是否位於事件的边缘。

They detected 112 sentinel lymph nodes in 71 patients (97%), including 64 (88%) in whom lymph nodes were stained blue after intraparenchmal injection of isosulfan blue, and 61 (84%) in whom lymph nodes were radioactive, reflecting uptake of radiocolloid injected intradermally.

研究者检测71位患者（97％）的112个前哨淋巴结，其中有64位患者（88％）的患者软组织注射isosulfan blue后，其淋巴结被染成蓝色，61位患者（84％）的淋巴结有放射活性，这反映皮内注射的放射胶体被吸收。

The method comprises the following steps:(1) the nodes of the sensor adopt the delaminated structure; the program memorizer is divided into the microkernel region and the user program region; the microkernel region is a fixed region; and the user program region is a nonupdatable region;(2) in the sensor network, a function upgrading code image is encapsulated into a data packet and injected to the network by a sink node; under the control of the microkernel region, the data packet is diffused in the whole network in a gradual jumping mode and sent to each node of the network; and (3) the nodes of the sensor utilize the delaminated structure to realize the self-function updating, thereby completing the self-maintenance of the function of the nodes.

其步骤如下(1)传感器节点采用分层结构，程序存储器分为微内核区和用户程序区，微内核区为固定区，用户程序区为不可更新区。(2)传感器网络中sink节点将功能更新代码映像装入数据包并注入网络，在微内核区的控制下，数据包以逐跳的方式在整个网络中扩散，传送至网络中的每个节点。(3)传感器节点利用分层结构来实现自身的功能更新，完成节点的功能自维护。

According to the information of mobile sensor nodes and the range data by apperceiving the target,in the method,the position of the target can be calculated.Then the tracked orientation of every source node can be located according to the position of source nodes and target nodes,so the target can be tracked by source nodes based on these orientation.

利用测距定位的移动追踪方法，根据移动传感器信源节点的信息及感知目标所得的测距数据，推算出目标的位置，由信源节点与目标节点的位置分别确定各个信源节点的追踪方向，使移动传感器信源节点沿该方向追踪目标。

Wavelet packet decompresses vibration signals, and wavelet packet nodes which are sensitive to the change of state, as eigen-nodes, form a decomposition tree; the signal restructured at all eigen-nodes can be used as the fingerprint in many breaker diagnostic systems. Support vector machine with the "most important" factors at eigen-nodes as input vector classifies the states at "one to others" strategy.

首先利用小波包分解振动数据，提取状态变化敏感节点作为特征节点形成分解树，利用敏感节点重构完好状态振动信号，并以此作为当前大多断路器诊断系统中使用的指纹信号；同时提取特征节点最大系数形成特征向量，作为支持向量机的输入向量，使用&一对其余&策略进行特征分类。

Branches often 1 at lower nodes, initially 5–7(–12) at middle nodes, 9–11(–45) at upper nodes, on promontory, erect or deflexed, subequal or central branch strongly dominant at lower nodes; internodes ± terete.

在下部节的分枝通常1，最初5-7(-12)在中部节，节间的±圆柱状。

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