Firstly, the 3D solid model of the analyzed object is built directly in the FEM software ANSYS 8.0 without using other CAD software. The influence of the side sizes of solid elements on computing results and the influence of coupling ways between different parts on the modal parameters are researched by simply modeling. And a new connecting method about joints in ANSYS is proposed and applied to finite element modeling of the test-bed for spindle system. Furthermore, several different computing techniques for modal parameters extraction are compared in solving the finite element model of spindle system test-bed. Many modal solutions are also done to achieve the relationships between the whole or part stiffness value and computed modal parameters. The laws about joint rigid parameters" influences on modal parameters are discussed by means of altering their values for conjoint parts. And by changing local rigid parameter values, the different location selections" influence on computed modal parameters is also studied.

The representative minority cultural relic-pottery relic of Buyi minority and the two wooden masks is taken as the research object. Firstly, Hiscanner laser scan detector was adapted for data collection, and then obtain point cloud data which could be recorded on disc for permanent saving was obtianed; Furthermore, the new popular reverse engineering software Geomagic for some disposals of point cloud data was adopted in data condensing, data mending, data filtering, feature line picking up to obtain NURBS surfaces; and then the error between the reconstructed CAD model and the point cloud data was evaluated to guarantee the precision of surface reconstruction to keep the relics keep its original appearance. In the end, the NURBS surfaces are imported to 3D software Solidworks and entities of CAD are generated by surface sewing, mold loft and ablating and other instructions.
选用有代表性的贵州少数民族文物―布依族酒壶、水壶以及木制傩戏面具作为研究对象,采用Hiscanner激光扫描测头对其进行数据采集,扫描得到的点云数据可刻录到光盘上作为文物数据永久保存;更进一步地,采用目前流行的逆向工程软件Geomagic studio对点云数据进行数据精简、数据滤波、数据修补、提取特征线等处理后得到NURBS曲面;为保证曲面模型重建的精度,在曲面重建模型后对其误差评价,通过控制误差的方式指导曲面模型重建,使重建的文物曲面模型能真实完整地反映原状;最后,在功能强大的三维造型软件Solidworks中导人重构的NURBS曲面进行曲面缝合、放样等,将其生成实体CAD模型,并对模型的局部特征进行适当的再设计以实现文物实体模型的优化。

In those well-formed geometric structures, not only does the scripture express its mystery and the beauty of cutting, but it stands for the symbol of Buddhism. There are numerous works demonstrate this statement, such as "Ark of Dream,""Scriptures,""Pilgrimage of Buddhist Scriptures,""Spiral Scriptures,""Floating,""Pipal,""Big Spiral Scriptures,""Golden Mandala." Besides from placing scripture and leather into fine spatial arrangement, Huang Gang fills the golden background with dark brown dripping technique or paints a large red star. The red star series, which is combined and abstracted from China's interpretation for red, has a particular meaning.
在有规律的几何形式构成画面之中,除了倾心展现经版的刀笔之美、经文的神秘意味,经版始终是菩提灵性的表征符号,而不仅仅是一种简洁的对象,例如《梦之舟》、《佛经》、《朝经之路》、《转经》、《行云流水》、《菩提树》、《大转经》、《金色的曼陀罗》等,进一步地,在空间表现上,在经版或皮革构成的实体空间之外,其非实体空间恰当地运用了书写性和涂绘性的表现主义语言风格,在经版的金黄色域背景上涂绘、滴沥黑褐色,有的则间以大漆涂刷那些红星。

The men who introduced this doctrine did not posit Ideas of classes within which they recognized priority and posteriority (which is the reason why they did not maintain the existence of an Idea embracing all numbers); but the term 'good' is used both in the category of substance and in that of quality and in that of relation, and that which is per se, i.e. substance, is prior in nature to the relative (for the latter is like an off shoot and accident of being); so that there could not be a common Idea set over all these goods.
因为,当两者都与我们亲善时,虔诚要求我们把真理置于友谊的上面,提出这一学说的人没有把类的理念放置到他们提出的先天与后天范畴内(这也是他们没有坚持理念的存在涵盖所有数字的原因),但是"善"这一术语既在实体这一范畴内使用,也在性质和关系范畴内使用,而实体就其本身而言,在本质上优先于关系(因为后者就像派生物和偶然的存在一样),因此在所有这些善之上有一个普遍的善。
