In this thesis, we present a new channel scan method called "random scan" to reduce the delay. The scheme divides the beacon interval into several sections. In each beacon interval, only one section will be scanned and it will take multiple beacon intervals to scan all the section to cover the entire beacon interval.

在本论文我们提出一个减少IEEE 802.11无线网路之漫游所造成服务中断的机制称为随机扫描，此机制将标记间隔切割成数个区段，在每个标记间隔中，只对一个区段进行扫描，剩下的时间可继续正常的传输，以降低服务被中断的时间。

Time is always used as the most important parameter in the current network security visualization techniques on port scan.This makes the slow scan, the dynamic or random scan, concealed scan and spoofed scan hard to detect, and the detection results of the related security anomalies such as DDoS, worms, Trojans etc are bad too. Therefore, a novel network security visualization method for slow scan, concealed scan etc is proposed in this paper.

目前基于端口扫描的网络安全可视化技术常常以时间作为最重要参数指标，往往只能检测那些较快速地扫描行为，对强动态性、强随机性和强隐蔽性的与端口有关的安全事件如DDoS、蠕虫病毒、木马等效果并不好。

Considering the specialty of pseudo-random vector, a partial scan algorithm for BIST, which unifying the structure analysis and testability analysis, is presented in this paper. Then, the fault simulation experiments on ISCAS89 benchmark circuits by this algorithm is made, and the results, which made by the full scan algorithm and the partial scan algorithm only based on the structure analysis, is compared. The conclusion is achieved: for pseudo-random vector, compared with the full scan circuit and the circuit geted by partial scan algorithm only based on the structure analysis, the circuit geted by our partial scan algorithm can greatly reduce the test time with very close or even greater faults coverage and less area than the full scan.

考虑到伪随机测试向量的特殊性，本文借鉴确定性测试向量生成的部分扫描算法，在内建自测试环境中，提出一种综合结构分析和可测性分析的部分扫描算法，PSBAST，并运用此算法对ISCAS89 benchmark电路进行计算，并对经计算后得到的部分扫描电路进行故障模拟，最后将模拟结果与全扫描电路和一种仅考虑结构因素的部分扫描算法得到的结果进行详细分析和比较，结果表明：对于伪随机测试向量，相对于全扫描电路和由仅考虑结构因素的部分扫描算法得到的电路，本文提出的部分扫描算法得到的电路，能够在不低于全扫描结构故障覆盖率前提下，大幅度减少测试时间，并能降低测试面积开销。

Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.

使用16排螺旋CT对40例患者行头颈部CTA检查，随机分为两组，各20例，所有患者在CTA之前行脑CT平扫及脑CT灌注扫描，A组以CTP所显示的动脉峰值时间作为CTA的延迟时间，扫描方向为自头侧向足侧。B组使用造影剂浓度实时监控跟踪触发技术确定延迟时间，扫描方向自足侧向头侧扫描，两组CTA图像相对照。
