Optimization solution algorithm is the most important in topology optimization.Algorithms fit for discrete structure and continuum structure are all investigated. Thecharacteristic and different using limit of both optimization criteria method andmathematics programming method are all analyzed in this paper. OC algorithm and theseries MMA algorithm based on SIMP approach are deducedand used for the topology optimization problem of continuum structure.

The position of controlled structure was positively fed back to controller according to position measure and contraposition control, and position of controller was positively fed back to control structure to control the vibration of controlled structure.

将实际系统模型放置在仿真系统中进行半实物仿真控制。通过位置测量、对位控制，将受控结构位置正馈至控制器，再将控制器位置正馈给控制结构，控制受控结构的振动。

On one hand, globalization courses the change of space economic structure and the restructure of world urban systems. The space economic structure changes from industry chain to a value chain structure. On the other hand, more and more progress of regions and countries has been brought into the global economic network. The rivalry between these countries often present between regions and cities. The global competitive advantage of cosmopolis and the surrounding town compact districts is a critical component of the countrys integrate competitive advantage.

一方面，全球化导致空间经济结构的转型和世界城市体系的重组，以"产业链"为特征的空间经济结构正在转变成为以"价值链"为特征的空间经济结构；另一方面，各国的城市和区域的发展越来越纳入全球经济网络，经济全球化背景下的国家竞争已经更多地表现为城市和区域之间的竞争，以国际大都市为核心的城镇密集区域的国际竞争力是国家综合竞争力的重要组成部分。

For analysis of traditional experimental modal, hammer and shaker are often used to force the structure as the clamped-clamped beam to raise the vibration of the structure, meanwhile accelerometer is placed on the structure as a sensor, then the modal parameter could be found.

传统实验模态分析大多使用冲击鎚或激振器施加点力於结构例如固定梁，做为驱动器激发结构的振动，利用加速度计做为感测器置於结构上，以求取结构之模态参数，但传统之模态实验设备都有实验操作不易以及价格昂贵的缺点。

First, from room temperature to 500oC, the shell structure is amorphous with crinkly and airtight character. The shell structure begins to change into γ-Al2O3 and α-Al2O3 at 900oC. The surface of shells shows nano-sized pores at 900oC from SEM and BET analyses. When heated to 1000oC and 1100oC, the shell forms stable α-Al2O3 structure with smooth surface. Cracks often occur at the triple grain junctions. The specific surface area and the total pore volume of the hollow spheres increase with the calcination temperature.

首先，将锻烧温度由室温提升至500℃时，球壳属非晶相皱褶状致密结构；在900℃时开始有γ-Al2O3相及些许的α-Al2O3相出现，由SEM及BET结果得知，900℃之球壳表面有许多奈米级孔洞出现；当加热至1000℃和1100℃时，球壳形成稳定相之Al2O3结构，壳层表面趋於平滑，且球壳在晶界处有微裂缝存在；由BET 结果得知，比表面积及总孔洞体积会随锻烧温度之增加，有增加之趋势。

Research usejP.Haggett"s pattern of spatial structure and system, analysis technique of tourism market space and data of spot check to analyze the evolvement of spatial structure and problems of tourism development from six faces, move, path, crunode, significance of crunode, ground and diffuse. The law of the evolvement of spatial structure: First, tourism development keeps rising. Second, AR of xi"an is very big and stable, Xi"an is tourism hotspot and center. Third, origin market space sticks out east, and isn"t continuous. Fourth, tourist proportion of XAZ follows the low of distance decay. Distance decay is very obvious in adjacent zone because of little attraction. Sixth, the spatial distribution of tourist origins has become less concentrated. Tourist origins of east China develop quickly. Three problems: First, tourism development is very unbalance between Xian and its adjacent zone.

西安及毗邻地区的国内客源市场空间结构的研究，采用了英国著名地理学家哈格特描述的空间结构模式与秩序，利用旅游市场空间分析技术，借助市场抽样调查、数量分析，从运动模式、路径、结点、结点层次、地面和扩散6个层方面进行了剖析，归纳总结出5个客源市场空间结构演变规律：(1)旅游业发展整体保持增长趋势；(2)客源吸引半径大而稳定，西安市是全国性的旅游热点城市和旅游中心城市；(3)客源市场分布突向东部，呈不连续分布；(4)游客比重的距离衰减普遍存在，毗邻地区吸引物及自然吸引物吸引力较小，距离率减明显；(5)客源集中度减小，客源市场发展呈现跳跃式增长的演变规律。3个市场拓展面临的问题：(1)西安与毗邻地区间旅游业发展不平衡现象明显；(2)客源市场区位不佳；(3)旅游产品单一老化，类型单调乏味。
