This article takes the teaching of conic sections as an example. By designing worksheets, teachers can introduce the historical material about conic sections to students. By way of using Apollonius' definition of parabola, ellipse and hyperbola, teachers can introduce the geometric aspect of "conic section" to students. By using the concept of " latus rectum " in Conics , we can connect "conic sections"-- representation of geometrical aspect, with "the equation of conic sections"-- representation of algebraic aspect to improving insufficiency of text books.

同时本文也试著从历史文本中寻找材料，简单举例说明数学教师可以如何应用这些史料在几何单元教学上，例如三角函数的正余弦定理，最后再以圆锥曲线的正焦弦为例，说明如何利用数学史料於此单元的教学，尤其是阿波罗尼斯的《锥线论》中对圆锥曲线的3个命题，将此3个命题的内容与意涵，尤其是正焦弦在圆锥曲线的几何意义上所扮演的角色，将其适当地融入教学中，将可使学生真正学习圆锥曲线的几何知识，而不再只是代数形式的几何知识。

The data analysis shows that: 1 different texture parameters have a clear scattered distribution, 2 the main direction of texture is the direction represented by the maximum parameter of Gauss-MRF parameters, and 3 for those samples basing the same main direction, the finer the texture is, the greater the corresponding parameter is, and the smaller the other parameters are; and the higher the order of Gauss-MRF is, the more clearly the texture is described.

数据分析表明，各不同纹理特征参数之间具有明显的分布性；Gauss-MRF参数值最大的参数所表示的纹理集聚为向为纹理的主方向；对于纹理主方向相同的样本，纹理越细致，其相应参数越大，而其他参数越小；Gauss-MRF阶数越高，纹理描述越细致：在2阶Gauss-MRF模型情况下，弦切纹理的B1参数大于径切纹理的B1；弦切纹理的B2、B3、B4分别小于径切纹理的B2、B3、B4。

Based on Crank-Nicoson's technique, and a new approach for the numerical simulation of the model is raised. The truncation error of the one step difference method reaches O (△t^2+△x^2) and of quite good stability condition.

基于Coriolis加速度和Lagrangian应力公式，利用Newton第二定律导出轴向加速度运动弦线横向振动的动力学模型；通过线性变换将方程化为一阶无量纲的非线性微分方程组；并利用Crank-Nicoson的中点离散技巧，给出运动方程的单步二阶差分方法；算法把对运动方程和本构方程分别离散，使之可以用于不同本构的运动弦线的数值仿真。

Featuring the BBC Radio 2 Concert Orchestra and working with orchestral arranger Fiachra Trench and producer Mitchell Froom, who has worked with The Corrs on three previous albums, the band set out to create an eclectic mixture of songs and instrumental airs.

因为在英国广播公司的第二调频的一场管弦音乐会的广播中，以及曾经与我们合作过的管弦策划Fiachra Trench和电影制片人Mitchell Froom对我们的想法起到了决定性的作用，在曾经参与制作可儿家族的前三张专辑中，这支乐队在歌曲和乐器编排中创作出了一种比较折衷的混合形式

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied. Base on chord high difference algorithm, a new one called chord high difference-ratio algorithm is proposed to improve veracity and robusticity of singular points elimination. Then, a registration algorithm based on local surface reconstruction is proposed, which avoids infaust influence coming from single reference point error.

在弦高差法的基础上，提出了全新的弦高差—比法，提高了异常点剔除的准确性和柔韧性；提出了一种基于局部图形重构的重定位方法，该方法通过对特征球的最小二乘拟合，消除了单一参考点的精度对重定位的影响；在此基础上对重定位的误差进行了详细的分析，给出了精确的误差值，从数学的角度保证了重定位的精度；在三角网格法的基础上提出了基于Delaunay三角剖分的半径补偿新方法，有效改善了补偿矢量的计算效率和准确性。

Secondly, by the analysis of influencing factors of collapsibility of loessal foundation, results indicated that at the basis of the grey incidence analysis on influencing factors of collapsibility of loessal foundation,the void ratio is the superior and steadily influencing factor of collapsibility at all events and other influencing factors will have different degree of influence according to the specific conditions of loess foundation.

通过分析影响黄土湿陷性变形的因素，对于湿陷变形因素的关联分析，可以看出土性指标对湿陷性的影响程度，孔隙比的影响比较突出，基本上可以认为是在土性指标对湿陷性的影响程度中最大的，其它指标会因土质含量、黄土的类型不同而影响各异。总之，本文应用灰色系统理论的关联分析法对应用广泛的工程实用模型变形计算方法做一些因素分析、进行反思，同时证明了弦线模量法计算沉降是值得大力推广的，弦线模量法计算沉降在将来的工程实践中必将带来更为可观的社会经济效益。

In turn, further adjustments to cope with the different tensions placed on the guitar may be required, and in extreme tunings, fitting different components to cope with the different gauges used.

同样为了应对吉他所受的不同张力而做一些调节也是必要的，在一些极端的调弦法里，还会用到一些不同的组件来应对不同型号的弦。

EXP coated silverplated copper classical strings have a natural round wound feel and sound fresh and bright with a "new string tone" that lasts three to four times longer than traditional guitar strings.

EXP琴弦的声音清新亮丽，给人耳目一新的感觉，而寿命则可以达到普通琴弦的三到四倍。 EXP系列琴弦的高音弦与Pro Arte系列中对应的型号是相同的，只在低音弦上有所区别。
