前后的

Floating island over the Central Business District The CBD in Beijing was built according to the western vision of modernization created in the last century, which is regarded as an expression of wealth and status. However, unlike Western countries, Beijing's CBD isn't characterized by Western countries' ambition to push the limits of technology and the present, nor does it attempt to set future new standards for itself.

CBD上空的浮游之岛北京的CBD是依照上个世纪初现代主义革命前后的西方标准建造的，建筑高度被认为是资本和地位的表达，但本质的不同是，它完全没有一百年前的西方人建造摩天楼时挑战技术和未来的野心，更没有任何试图为自己的未来建立新标准的意图。

This paper, which focused on the structure optimization theory and method, has finished such studies as follows: The three dimension model has been built, which provide the necessary conditions for the building of the dynamics equivalent model. By the launch dynamics simulation, the loads of the key joints when the rocket is launched has been got, which provide the necessary data for the finite element analysis and the structure optimization. The finite element model of the excess weight parts of the rocket has been built, buy the finite element intension analysis of the model in two conditions, the displacement and the stress of the key points have been got, which make us know the distributing of the stress and the transmogrification of the part. To satisfy the intension and the precision design request and to decrease the weight of the part as many as possible, the part has been topology optimized by the structure optimization theory and method. After that, the new model has been analysis in structure and launch dynamics. The contrast of the character change of the old part and the new part and the influence on the rocket system have been studied.

Since the lengths of the line segments and the angles between line segments are treated as representation parameters, it is convenient to construct energy function and to deal with displacement and length constraints. Based on this advantage, a parametrical model for human body is proposed, which can easily produce human body models with different feature sizes. The above method is just suitable for polylines. Therefore, a generic deformation method for both discrete curves and surfaces is presented. The energy function is constructed by analyzing the relationship of the points before and after deformation. Together with the displacement constraints, the deformation problem is converted to a convex quadratic programming. A necessary condition for constraint points and a sufficient condition for the uniqueness of solution are given. The proposed method can be combined with skeleton-driven animation to control the deformation.

将线段长度与线段之间的角度作为表示参数，既有利于能量函数的构造，又便于处理位移约束和长度内蕴约束条件，利用这一优势，将其应用于三维人体的参数化建模，可以方便地产生具有不同特征尺寸参数的人体模型，由于这种方法只适用于折线变形，具有较大局限性，因此，本文进一步提出一种较通用的离散曲线曲面变形方法，通过分析变形前后的位置关系来构造能量函数，再加上位移约束条件，将变形问题转化为一个凸二次规划问题，并且给出了约束点应满足的必要条件及模型解唯一的充分条件，这种方法还可以与骨架驱动变形的思想相结合，能更好的控制变形。

Clearly there are major differences in Chi Chia-Hwa's works before 1996 and those from 1996 to his solo exhibition in 1998. The former overflow with a youthful playfulness and chaos. In 1996 his work suddenly cooled down, replaced with more placid, sober pictures. The size of the difference between these two periods seems to indicate a "shock" of some kind.

但是很明显的，1996年以前的作品和1996年至1998年间个展的作品极为不同，前者洋溢著一种年轻心灵的奔放及混乱的力量，在1996年时，突然冷却下来，代之以一种沉静、冷眼静观的画面，由於前后的差异之大，彷佛显现出人类心灵的一种「震惊」般的痕迹。

In the fifth chapter, the stall regulated wind turbines are simulated on the zero-yaw and yawed configurations. The former are solved under non-inertial rotating coordinate system and the latter under inertial coordinate system.

第五章为风轮叶片的流场数值模拟，对失速限制型风轮叶片(NREL Phase-Ⅵ)在轴流和偏航状态下的流场进行了数值模拟，其中轴流状态采用在旋转坐标系下进行求解的方法，研究了风轮叶片在经历失速前后的流场变化、桨叶载荷分布，对所产生的扭矩、以及附加的在挥舞和摆振方向的力矩进行了分析。

The paper reports the results of investigation for the operation condition of the ball-mill coal-pulverizing system of 100MW and larger power station. Based on the analysis of the ball-mill mechanism, the problem was found that the energy consumption on empty load of ball mill is more than 90% of the total energy consumption and the small iron balls that has lost mill ability and the iron component in the coal increased the mill s energy consumption. Thus automatic ball filter equipment was developed and in...
