Because it emphasizes on algebraic method, geometric intuition are lose. Especially in the unit of conic section, although "the unity of geometrical material and algebraic symbol "is the teaching objective of text books, but according to the material of text books, it is difficult for students to arrive.

本文首先试著分析目前高中数学教科书中，对於几何部份的教材编写上，由於编写者的意识型态不同，理念不同，数学教师对教科书的诠释就会因此而有不同，因而造成目前高中几何教学著重在代数方程式上的一些问题。

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。

根据等螺旋锥铣刀几何原理，提出一种借助附加装置在万能铣床上进行等螺旋角锥铣刀粗加工工艺，介绍了该方法加工锥铣刀时工作铣刀的运动方程；给出了附加装置的设计原理，通过对用此方法加工出的铣刀参数进行测试，证明了这种方法的可行性和实用性。

The horizontal universal milling machine technological transformation based on Mitsubishi PLC;2. Analysis of some important points for makinghelical gear on universal milling machine ;3. According to the geometrical principle of conical milling cutter with equal helix angle, a new process of rough machining of conical milling cutter with equal helix angle on universal milling machine by using additive equipment is presented.

根据等螺旋锥铣刀几何原理，提出一种借助附加装置在万能铣床上进行等螺旋角锥铣刀粗加工工艺，介绍了该方法加工锥铣刀时工作铣刀的运动方程；给出了附加装置的设计原理，通过对用此方法加工出的铣刀参数进行测试，证明了这种方法的可行性和实用性。

In the teaching of central field, we should pay attention to turning the relative motion of two - body into one dimentuonal radial motion by introducing two physical concepts of reduced mass and effective potential energy, and we should also pay attention that the area law is the geometrical description of the conservation of angular momentum in the central field.

在有心力场教学中，应着重强调指出：通过引入折合质量和有效势能这两个物理量，把二体相对运动问题转化为单体沿径向的一维运动问题；以及面积定律是质心在有心力场中角动量守恒的几何描述。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
