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 principles of suppressing random noises with K-L transformation in wavelet conversion domain are that 1 wavelet decomposition is carried out on seismic signals to form wavelet packet sections in time sharing and frequency division, 2 K-L transformation is utilized to remove noises on sections, and 3 the de-noise wavelet packet sections are reconstituted into seismic sections to remove random noises.

介绍了小波变换域K-L变换压制随机噪声的基本原理,即先将地震信号进行小波分解形成分时分频的小波包剖面,然后用K-L,变换对小波包剖面进行去噪,再将去噪后的小波包剖面重构回地震剖面,从而达到消除随机噪声的目的。

Besides, both sections Dentata and Pterostoechas contained camphor, and the averaged fragrance scores of species Lavandula were ranged from 2 to 3.

Dentata 及Pterostoechas 两sections具有樟脑味,属於Lavandula angustifolia 的品种则具有高度香气。

The fragrance of lavender varieties was divided into six levels (score 1 represented fantasy fragrance, and score 6 represented poor fragrance), and sections Lavandula and Pterostoechas were evaluated with score 2 and score 6, respectively.

而薰衣草品种香气则被区分为六个等级﹝1代表香气等级最优良,6代表香气等级最低劣﹞,其中Lavandula 与Pterostoechas 这两个sections的等级分别为2 和6。

Thirty lavender varieties in five sections were investigated in leaf characters and fragrance. Sections Lavandula and Pterostoechas possessed the highest (7.23) and the lowest (2.01) value of the length/width, respectively. Because sections Lavandula (3.59cm) and Stoechas (3.00cm) possessed the approximate value of the leaf length and leaf width, lavender varieties couldn't be identified only by the leaf character.

在五个不同sections的叶片长宽比调查中,Lavandula与 Pterostoechas 这两个sections分别具有最高(7.23)及最低的数值(2.01);而Lavandula (3.59)与Stoechas (3.00)两个sections的叶长平均值相近;且在叶宽的调查中,Lavandula (0.49)与Stoechas (0.47)两sections的平均值仍然非常相近,表示仅由叶片外观性状无法精确的判别薰衣草品种。

Another command that can give you extra information about program sections is maint info sections.

Another command that can give you extra information about program sections is maint info sections.

另一个能给你有关程式段的额外信息的命令是 maint info sections。

In addition, maint info sections provides the following command options which may be arbitrarily combined

另外,maint info sections 提供下面的命令行选项可以随意的组合

A wind- and motor-powered land vehicle with a fore-and-aft longitudinal axis comprising a body supported by wheels, at least one of said wheels fixed to rotate in a plane parallel to the fore-and-aft axis of said vehicle, an airfoil system comprised of two vertically extending airfoils rigidly mounted on said body in an arrangement having bilateral symmetry about a vertical plane through said fore-and-aft axis, said airfoil system providing a forward propelling force of said vehicle when the airfoil system is subjected to certain cross wind conditions, and self-contained motor propulsion means on said vehicle for providing acceleration from a stationary position and for propelling the vehicle either independently or in combination with propelling forces generated by wind action on said airfoil system, each airfoil having a plurality of airfoil sections telescopically fitted together, the lower airfoil section being rigidly mounted in fixed relationship to said body, said airfoil system including a retracting mechanism for lowering upper airfoil sections of said airfoil system when desired and for subsequently extending said airfoil system, said retracting mechanism including a plurality of linkages interconnecting said sections and an actuator means operatively connected between said body and to said linkages for lowering and extending each airfoil, and an intermediate airfoil extending between the upper sections of each of said airfoils so as to provide an inverted U-shaped airfoil.
