IRHV was demonstrated in 153/270(56.7%), CHV was demonstrated in 68/270(25.2%). Conclusions Portal and hepatic vein can be displayed accurately by 3D 64-MSCT angiography , which could measure diameter or other information about the veins at any cross-section. Meanwhile, more anatomic information could be provided for hepatic segments resection and liver transplantation directively. Portal and hepatic vein diseases could be diagnosed by 3D 64-MSCTA accurately and directly also.

与前两次大规模的中西文化交流活动不同的是，它不是在主动选择、自主交流与平等互换的基础上展开的，而是在帝国主义列强入侵这一形势下被动地、扭曲地进行的，因而具有其特殊的历史背景与时代特征。

A general laser scanning altimetry equation is developed that describes an ideal system, followed by developing an error model for the laser scanner, and the INS and GPS units. The result is a modified laser equation that contains all errors introduced. The error model is evaluated by analyzing the difference between errorless equation and laser equation with errors.

本文从机载激光扫描测高对地定位的几何模型出发，详细推导了各项误差对机载激光扫描测高对地定位结果的影响关系式；详细分析了不同误差对激光脚点坐标的影响规律，并给出了相应的数值结果和量化指标。

Many structural deficiencies and mistakes were highlighted, which including excessive horizontal displacement in the ground, more severe damaged transition layer (the first masonry structure layer), ground with farraginous structure, and poor construction quality. Finally, lateral stiffness ratio of the second to ground story in masonry buildings with RC frame structure at the bottom will be optimized following difference of materials between the ground floor and the upper floors. The strength and the ductility of transition layer, as well as shear walls in the ground floor, are crucial to keep the building standing during large earthquake.

在介绍和总结了汶川地震中底框砖房的表现―底层过大的水平侧移、过渡层严重破坏或完全坍塌、底层严重破坏或房屋完全倒塌、上部砌体整体发生侧移、以及设计一和施工质量良好的底层抗震墙砖房&大震不倒&的基础上，得出以下结论和建议：在抗震设防地区应禁止使用部分底框砖房，地震中过渡层的实际受力情况与设计所采用的受力状态有明显的区别，规范应考虑砌体和钢筋混凝土材料的不同力学性质来制定上下层刚度比要求，明确对过渡层的延性和强度要求，明确该类结构抗震概念设计的具体措施。
