The dissertation includes the work as follows: Firstly, we present a random graph model with spatial reuse for a dense MANET which using directional antennas. The analytic formula of several important performance parameters for the MANET are obtained under the DSR routing protocol, such as the average flooding distance, the probability generating function of the flooding distance, the probability of a flooding route to be symmetrically valid, the average time to find a symmetrically valid route and the cost to successfully route a data packet to its destination. We compare the two models with spatial reuse and without spatial reuse by evaluating these parameters. It is shown that the spatial reuse model is much more effcctive in terms of the performance of the dense network with directional antenna, because the bigger is the degree of spatial reuse, the smaller is the average flooding distance.

在定向天线技术的支持下，建立了移动自组网络空间可重用的贝努利随机图模型，获得了DSR路由协议下平均泛洪距离的解析公式和泛洪距离的概率母函数：给出了有效对称路由概率、发现有效路由平均时间、成功路由代价等关键性能参数的解析分析；在网络性能参数定量分析的基础上，对空间可重用和无重用的网络进行了比较分析，结果显示空间重用度增大，则平均泛洪距离、路由发现时延、网络代价减少。

Results It was found that the dense artery sign of MCA existed in the first CT scanning. The dense artery sign of MCA was like a"stick"or"punctiform", and its CT value was over 60 Hu. In the second CT scanning (24 hours after the first scan), a big area of low density in the region supplied by MCA was shown.

结果 26例患者发病早期（1～6h）的CT 检查均见一侧大脑中动脉致密动脉征，呈"条状"或"点状"，CT值大于60Hu；发病后24h复查，该侧大脑中动脉血供区均呈大片状低密度影。

Pore structure experiment shows that porosity of high volume fine mineral mixture RPC is about 5%, the pore distribution is uniform and the main pore is small. When the cement content of high volume fine mineral mixture RFC is 300 kg/m^3, its sclerotium hydration products is dense packed by irregular equal Ⅲ style C-S-H gels. The gels are fine, dense, and integrate with the aggregate.
