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。

It is available by changing traditional scan design using a scan register,whose length is equal to that of scan chain.

该结构是利用一个和扫描链等长的扫描移位寄存器，对传统扫描链进行改造得到的。

A hard disk scanning procedure used to do full scan found 7094 bytes of bad sectors, and prompted "ScanDisk found in the wrong drive and fully restored," when the prompt re-scan "scan disk in this drive did not find any problem ", still shows that the section 7094 bad sectors, hard to access with all the normal data.

一硬盘用磁盘扫描程序做完全扫描时发现有7094字节的坏扇区，并提示"磁盘扫描程序在此驱动器找到错误并完全修复"，再次扫描时提示"磁盘扫描程序在此驱动器没找到任何问题"，却仍显示有7094。了节坏扇区，用硬盘存取数据时一切正常。

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。

Collecting a total of 102 cases(107eyes) of pations with traumatic optic neuropathy that underwent edoscopic optic nerve decompression surgery during December 1999 - April 2008 line,retrospective analysis of CT performance for the optic canal and paranasal sinuses,and Comparison of them with surgical results.102 cases of patients performed routine and coronal axial sinus CT scans,the optic canal zone wi th thin target scan,line of nasal tip and the anterior clinoid process connection as baseline for axis scan,and the vertical line of "bed nasal line" as baseline for coronal scan.

方法收集1999年12月-2008年4月间在青医附院耳鼻喉科行鼻内镜下视神经减压手术的外伤性视神经病患者的病例，共102例(107眼)，回顾分析其鼻窦及视神经管CT表现，并查看手术记录描述，将CT结果与术中所见情况进行对比分析。102例患者术前常规行轴位及冠状位鼻窦CT扫描，视神经管区行薄层靶扫描，以骨性鼻尖与前床突的连线为轴位扫描基线，以&床鼻线&的垂直线为冠状位扫描基线。

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。
