For the application of Mathematica in the differential geometry,this paper introduces how to processe the curve curvature and the torsion questions,the graphic expression of the curvature and the torsions,and draw curves by the curvature and the torsions. Curvature ; torsion ; solution curve ; osculating plane ; natural parameter ; natural equation

利用Mathematica，只要输入有关系统命令就可以得到期望的结果。1曲率和挠率及其图形意义假设R3上的曲线一般参数表示为r=r它的曲率和挠率计算公式是：κ=‖r′×r&‖‖r′‖3τ=‖r′×r‖我们知道，空间曲线r=r在一点(s=s0)邻近的近似方程为ξ=sη=120κs2ζ=160κ0τs3通过近似方程可以确定曲线在其基本三棱形的三个平面(即密切平面，法平面，从切平面)上的投

What marked them out for persecution was not so much their theory of the inward light or their rejection of rites and sacraments, as their refusal to pay tithes, or take the oaths prescribed by law, or to have anything to do with the army; these offences being aggravated in the estimation of the magistrates by their obstinacy in refusing to uncover their head in court and "thouing and theeing" the judges.

什麼标志著他们的迫害，没有那麼多的理论的外来光线或拒绝仪式和圣礼，因为它们拒绝支付什一税，或采取宣誓由法律规定，或有任何与军队；这些罪行严重的估计法官其顽固地拒绝揭露其头部在法庭上和& thouing和theeing &的法官。

Before the Stoics, the Cynics, both in theory and in practice, had based their rules of conduct on the principle that nothing natural can be morally wrong.

前stoics ，批评，无论是在理论和实践上，已根据其议事规则进行对等原则的任何自然可以在道德上是错误。

WestLB, the shakiest of Germany's state-owned wholesale banks, or Landesbanken , prominently displays an "overview" of the bank's many "protection mechanisms" on its site.

这家德国国有批发银行当中最摇摇欲坠的西德意志银行，在其银行网站的醒目位置上，打出其银行许多&保护机构&的概况。

Whether in its narrow German usage or its more generic sense, pietism represented a complex phenomenon.

无论是在其狭隘的德国使用或其较一般意义上说，虔诚主义派一个复杂的现象。

Komenaka, MD, from Columbia Presbyterian Medical Center in New York City, and colleagues."Phyllodes tumors are uncommon enough to lack a well-defined, evidence-based diagnostic algorithm. Because of their clinical similarity to fibroadenoma, many are initially managed with enucleation, resulting in the frequent need for reoperation."

Komenaka博士表示，粗针切片检查可以在门诊时进行，其侵入性是最低限度的，而且费用上也具有应用可能性，以目前对叶状瘤的认识还不足能良好地辨别出来，因为它们与纤维性瘤在临床上是相似的，很多病例一开始进行肿瘤切除术，但是之后却还需要再进行手术。

Therefore, literature education began to develop a kind of education with attention to knowledge and skill, because it is hard to implement the education of aesthetics during the curriculum. The literature education in high school is close to pre-education for college, it mainly teach history of literature. Chapter 5 focuses on the influence from scientific concepts on literature education during 1930s. This influence can be detected easily from text books, among them, the percentage of literal writings becomes stable.

中学文学教育以独立的学程谋求自身价值的实现，但毕竟蕴涵在语文教育中，并不能摆脱社会现实、学制宗旨对国语教育的各项要求，文学教育开始向一种知识技能型的教育靠拢，以文学作品为中心的美育及情感教育意义上&文学&很难在课堂上实现；高中的文学教育则近于大学的&预科&式教育，文史是其主要的形态。

The relationships between welding pool width, wire extension and welding parameters including welding current duty ratio, base current, peak current, welding speed and wire-feeding speed were studied. Through large numbers of welding experiments, aluminum alloy pulsed MIG welding dynamic process were identified by the curve fitting method, and the mathematical models between welding current duty ratio, base current, welding speed, wire-feeding speed and wire extension were obtained, succeeding the model between the above parameters and weld pool width.

介绍了铝合金MIG焊焊接电流占空比、基值电流、峰值电流、焊接速度、送丝速度对熔宽的影响规律，并在其基础上，通过平板堆焊试验研究了这些参数对焊接干伸长的影响规律；在铝合金机器人脉冲MIG焊平板堆焊过程各焊接参数与正面熔宽之间的传递函数的基础上，采用铝合金平板堆焊阶跃试验，利用曲线拟合法辨识了铝合金机器人脉冲MIG焊动态过程传递函数，建立了焊接电流占空比、基值电流、焊接速度、送丝速度与焊接干伸长之间的对象数学模型。

The increase in WHC of resistant starch having guar gum over resistant starches with guar gum and different chemical agents could be ascribed to non interference in the chemical configuration and composition especially in greater number of hydrophilic sites on the gum that allows the occlusion of water within the structure.

单独含有瓜尔豆胶的抗性淀粉其WHC比含有瓜尔豆胶和其他化学试剂的抗性淀粉高是因为在胶上一些亲水基团上无化学构象，这导致了水在结构中的封闭。

Then after a semi-rigid joint behavior can be modeled as a finite stiffness rotation spring, base on rotation and displacement equation derive the element stiffness matrixes with semi-rigid connections where the effects of jointed flexibility and shear forces in the connection deformations have been considered in and fixed-end forces are modified. Finally, a program for calculating system reliability of semi-ridge steel frames with Monte carlo method and finite element analysis has compiled for calculating and analyzing.

接着本文在介绍和分析半刚性连接弯矩和转角关系模型的基础上，用带有转动刚度的弹簧表征半刚性连接，推导出半刚性连接的刚度矩阵，对固端力进行修正，同时考虑了剪切变形的影响，编制了半刚接钢结构平面框架的有限元程序BHPFL，并在其基础上编制了基于蒙特卡洛法的Monte Carlo-BHPFL 有限元相结合的方法，进行体系可靠度的分析。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
