The measuring data after pre-processing was fitted with NURBS curve with constructing the non-uniform node vector using the method of cumulating chord length and optimizing the rights of NURBS curve restrictively. The formula of surface skinning which can be realized by programming was proposed on the basis of the foundation formulas in existence, then NURBS curves was skinned to gain the corresponding NURBS surface.

对经过预处理后的测量点数据，通过采用累积弦长法构造非均匀节点矢量和对权因子的约束优化，进行测量点数据的NURBS 曲线拟合，在现有基本公式的基础上推导出了可以编程实现的曲面放样公式，对得到的NURBS 曲线进行放样处理，最终得到了测量点数据的NURBS 曲面。

Once again with self-winding mechanisms, Rolex saw the way the market was going, saw the mistakes all their predecessors had made and neatly sidestepped them all. Whilst many other competing self winding systems have arisen in the 65 years since Rolex introduced the Auto Rotor system, the vast majority of all automatic watches now use a version of the Rolex concept.

自动上弦机械，ROLEX看到了市场的发展方向，看到并绕开了了前人所犯的错误，在ROLEX推出他的自动摆陀系统的65年间曾有大量的其他自动上链系统出现，但现今绝大多数自动表使用的是ROLEX的技术。

In this thesis, several kinds of spherical curvature measurement methods are introduced, and the "arch-high and chord-length method" is selected after introduction of the existing methods, and then the novel type of instrument for measuring spherical curvature with the variable ring is developed. In research, the grating sensor, integrated circuits and other new technologies are adopted and integrated. As a result of this, Its specific technical indicator is 0.1um in absolute accuracy, 0.01% in relative accuracy, and 0.001% in repeat accuracy.

Through the time and space, the blink of tears likes warm strings play songs on the mottled old tree. The unforgotten track of time broke the dream of memories, sang a song in the muddy space.

穿越的时空，点点的泪光，犹如一张温柔的弦，在斑驳的老树叶上轻弹，忘不了时间的痕迹，踏碎了记忆的美梦，在浑浊的空间里鸣唱。

2The static behavior of one prestressed spatial truss string structure is analyzed systematically in this paper. The change of the structural internal forces and displacements with the rise-to-span ratio, sag ratio, prestress and the number of brace struts is studied and the influence of these parameters on the mechanical behavior is discussed compressively in detail.
