The core idea of the method is to reduce the Hough cumulative dimension of the circle detection based on classical Hough transform, and convert the threedimensional statistical parameter based on the traditional circle Hough transform to two-dimensional parametric statistics about the center of a circle and one-dimensional statistical parameter about the radius of a circle.

给出了一种基于Hough变换的同心圆检测方法，其核心思想是降低经典Hough变换圆检测中的Hough累积维数，将经典Hough变换圆检测时的三维参量统计，转变成基于弦中点的圆心和半径的参量统计。

Finally,a reductionism way is put forward to computing the drop length, it may be useful to the construction budget.

最后，本文提出了一种简化计算吊弦长度的方法，该方法在工程预算中有一定的意义。

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。

Its role is to stop the excessive reverberation of these longer strings.

它的作用就是个阻止这些长弦音的过度回响。

For the robust performance test, the sine or square wave is added on the operating point to be viewed as the external disturbance.

在直流工作点加入弦波或方波当作干扰，铁球皆能稳定地磁浮於空中，展现出系统的强健性能。

The results showed that the failure mode of roof truss is flexual-torsional buckling of top chord members, which accords with the phenomena observed during test, the ultimate load-bearing capacity is also very close to test data.

结果表明，屋架结构的破坏模式为上弦杆的整体弯扭屈曲，与试验观测到的现象一致，极限承载力和试验结果非常接近。

Part two: This paper attempt to design a retractable roof structure from architectu re,structure and mechanism in the kind of traveling trusses and flexible roofage thro ugh a real structure of the retractable roof in the walk street plaza of Henglong build ing. Summary of some important points in design were presented.The comparision of several kinds of structure was taked.

第二部分：本文以恒隆步行街广场屋盖工程为例，通过对比分析剪刀撑方式、倒三角桁架式和张弦梁形式的结构方案，最终选择了倒三角桁架式的可展桁架加柔性屋面材料的方案。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
