For my purpose is not to furnish mere matter of much talk, but to throw light upon the number of years from the foundation of the world, and to condemn the empty labour and trifling of these authors, because there have neither been twenty thousand times ten thousand years from the flood to the present time, as Plato said, affirming that there had been so many years; nor yet 15 times 10,375 years, as we have already mentioned Apollonius the Egyptian gave out; nor is the world uncreated, nor is there a spontaneous production of all things, as Pythagoras and the rest dreamed; but, being indeed created, it is also governed by the providence of God, who made all things; and the whole course of time and the years are made plain to those who wish to obey the truth.

我的目的不是为了提供单纯的事多谈，但以投掷轻后数年内，从基础的世界，并谴责空洞的劳动和琐碎的这些作者，因为那里既没有得到20000倍， 10 1000年，从洪水到现在的时间，正如柏拉图说，肯定有过了这么多年，也尚未15倍10375年，正如我们已经提到apollonius埃及了，也不是世界uncreated ，也不是有自发生产的所有事情，因为毕达哥拉斯和其余梦想，但目前确实造成了，它也是由普罗维登斯的上帝，谁做好了各种东西，以及整个过程中的时间及年资，都是平原那些要服从真理。

This is an efficient method for the traversal, because every transition can be calculated by two-dimensional array indexing.

这是一个的遍历高效方法，因为每次转换可以通过计算二维的数组索引得到。

On the basis of the mechanical principle of the stress function and its derivative on the boundry of elastomer and the method of Heaviside function, the stress calculation of the function of nonlinear distributed force on the undersurface of nonsymmetric wedge block has been obtained.

用应力函数及其导数在弹性体边界上的力学意义和海维赛函数的方法，对非对称楔形体在楔面下部承受非线性分布压力作用的问题进行了应力计算，给出了应力一般解并进行了讨论，其结果具有理论和实际意义。

Stressing on "fine reputation","quality","service","credit","practice", not only the grandeur.④Encouraging the innovation, not the unearthliness, playing down the effect of entertainment stars or idols, decreasing the fashion index.⑤"personality" is not the "self central". Social sense of responsibility and interpersonal "feeling of affinity" are both intensified.3.1.2 Factor analysis, revealing 19 value element vectors, which include "comfort","personality","simple","fine reputation","responsibility","service","price","wisdom","distinction","enthusiasm","stimulation","taste","sex difference","quality","vigor","idol","fashion","affinity","aesthetic" and so on. Four orientation diagrams coordinated with the average factors and the standard deviations of these 19 value elements, described the multi directional value orientation structure for China college students' sportswear consumption.3.1.3 Clustering analysis are applied to classify the former 19 value elements, which discovered that three inferior group are classified from the college students' consumption group based on the whole specimen data. It could be the reference of enterprise brand building for the orientation of consumption values.3.2 General personal values, self conception and demographic are lead into as three major variables for the interrelationship analysis of sportswear consumption value system.3.2.1 Firstly, the college students having their general values and existing the inferior group feature regarding to the consumption values.

三、研究的主要成果及其意义对中国大学生休闲服消费价值体系进行探索性分析1、首先对中国大学生休闲服消费价值观量化问卷所调查的样本数据进行频数统计趋向性分析，发现呈现的主要特点有：(1)"个性化"和"简约"已成为潮流，而寻"刺激"、找"激情"总体收敛；(2)追求"美感"，更不放弃"舒适"，两者兼得才是完美；(3)重"美誉"、讲"质量"，重"服务"、讲"信用"，求实际、不求高贵，"明智"有素；(4)求新不求怪异，明星、偶像效应淡化、时尚指数不高；(5)"个性化"不是"唯我化"，社会责任感和人际"亲和力"在强化。2、其次对样本数据进行因子分析，揭示出以"舒适"、"个性"、"简约"、"美誉"、"责任"、"服务"、"价格"、"明智"、"独特"、"激情"、"刺激"、"品位"、"性差"、"质量"、"活力"、"偶像"、"时尚"、"亲和"和"美感"等十九个价值元素为矢量的休闲服消费价值体系，并以因子均值和标准差为参数勾画出19个价值元素坐标四方位图，从总体上描述了中国大学生休闲服消费多维的价值取向结构。3、再者进行聚类分析，对上述十九个休闲服消费价值元素作不同量值的分类，发现在样本总量中可以细分为有较大区分度的三个类别，呈现出大学生消费群体中存在休闲服消费价值体系不同的亚群体，可为以消费价值观为取向的企业品牌价值定位提供参考基谱。

The ellipse curre equation of circular image is derived based on the theory of spatial analytic geometry and rotation matrix s representation with unit quaternion then a mathematical model of the distortion error is established which relates the distortion error to the foca length of the used CCD camera,the radius as well as the position and the attitude of the inspected circle directly.

研究三维视觉检测中圆的中心经针孔摄像机成像后存在畸变误差的问题，首先基于空间解析几何理论和旋转矩阵的四元数表示法推导出像平面上投影椭圆的参数方程；然后根据参数方程建立圆中心成像畸变误差的数学模型；最后对影响畸变误差的主要因素进行分析。
