几何作图 meaning in English
geometric construction
Examples
- Constructing directrix for conic curve
圆锥曲线准线的几何作图 - But with plotting method only safety is considered , no attention is paid to the economy
但几何作图方法只考虑了安全问题，而没有考虑经济问题。 - When two vessels meeting so close to result in risk of collision , what kind of action should be taken by one of the vessels to avoid collision can be got by plotting geometrically on the paper
摘要当两艘船舶相遇存在碰撞危险时，采取何种避碰行动可通过避碰几何作图来求取。 - In this way , we get result in long time and great error . we need a standard result on how to evaluate a student ' s grade . now on radar simulator we can n ' t get the standard result and this makes error on evaluation . at the same time , we can only get dcpa and tcpa on radar / arpa
在目前的雷达模拟器上，进行雷达标绘通常都是采用手工几何作图的方法进行的，时间长，误差大，而对于如何评价和确定被训练者的成绩，则必须有一个标准值即标准答案。 - On this condition the thesis proposes the computer aided design method about the protection area of lightning rod . on the basis of the forming principle , basic characteristics and main harm of lightning , this thesis firstly introduces the development of lightning protection , then discusses the principle of lightning rod protection and the calculation method of protection area through the analysis and introduction to additional calculation method ? electrical geometry construct , an improved measure is put forward in this paper
本文就是在此基础上，提出了对避雷针保护范围的计算机辅助设计。本文从雷电的形成、基本特点及其主要危害出发，简要介绍了防雷技术的发展过程，对避雷针保护的原理及保护范围的计算方法做出了较详细的阐述。通过对避雷针保护范围传统计算方法(电气几何作图法)的分析、介绍，提出了对该方法的改进措施。
