画法

Based on the traffic flow theory and the elements of projective transform in descriptive geometry, the key to the changepoint recognition was analyzed by the complanation of dualistic linear regression.

依据交通流理论，结合画法几何中投影变换原理，以二元线性回归平面化研究为例，对变点辨识的关键问题进行了分析。

This paper investigates the converse theorem of rectangular projection theorem in descriptive geometry,and furthermore supplements and confirms another converse theorem,If the projection of two lines intersecting vertically fo rms a rectangle on a certain projecting plane,at least one line of the two lines is parallel to the projecting plane.

通过对《画法几何学》中直角投影定理的逆定理的研究，得出："若垂直相交的两直线在某一投影面上投影成直角，则该两直线至少有一条直线平行于该投影面"的推论。

Relation between geometrical contour error of inner corner and machining condition is investigated by the experimental plan of Taguchi quality design. Through the quantitative analysis, the geometrical contour error is mainly affected by wire tension and flushing pressure. By regression analysis, a mathematical model is established to estimate cutting path error of corner cutting. According to the estimated cutting path error, the program path is corrected.

研究首先以田口式品质设计实验计画法来探讨加工参数与隅角形状误差间的关系，从变异数分析的结果得知，线张力与冲水压力是对於隅角精度影响最显著因子，应用回归分析建立转角加工路径误差量估测模式，利用此模式以预测不同加工条件下隅角加工路径误差量，依据预测加工路径误差量计算轨迹补偿量，实验结果证明本文所提出轨迹补偿策略可有效提高60%之隅角加工精度。

Firstly we have a deep research on the auto drawing methodof network diagram and critical path method.

首先研究了传统的以关键路径为基础的项目管理技术，主要包括网络图的画法，计算关键路径。

The article about Picasso inspired me to try to paint in a cubist style.

这篇关於毕卡索的文章激励我尝试立体派的画法。

Though after the invention of photography painters did not feel obliged to serve any longer as craftsmen reproducing reality, this did not mean that Daguerre's invention only encouraged abstract painting.

照相术发明后，虽然画家们感到没有必要再像匠人那样复制现实了，但这并不意味着达盖尔（ Daguerre ，译注：银版照相术的发明人）的发明仅仅催生了抽象画法。

In the 19th century, William Blake and Edgar Degas experimented with the technique

在19世纪，布雷克和窦加曾用此画法作画。

The suggested one is more effective for drawing generation of questions in descriptive geometry.

这一方法有助于提高求解画法几何问题的作图效率。

Along with the spreading of computer graphics in teaching and engineering,there are two opinions about dealing with descriptive geometry.

画法几何是研究在平面上用图形表示形体和解决空间几何问题的理论和方法的学科。

Along with the spreading of computer graphics in teaching and engineering, there are two opinions about how to deal with descriptive geometry.

画法几何是研究在平面上用图形表示形体和解决空间几何问题的理论和方法的学科。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
