n.畫直線用尺

Each step of the construction of a circle with straightedge and compass calls for finding a point of intersection. 用圓規(guī)、直尺作圓的每一步都需要找一個交點。

Trisecting an arbitrary angle with a compass and straightedge was one of the famous ancient Greeks unsolved construction problems. 用直尺和圓規(guī)三等分一個任意的角是古希臘著名的構造問題之一。

In this paper, an experiment of test scale of straightedge is introduced by theprinciple of the Moire fringe shift amplifier. 本文介紹利用莫阿條紋位移放大器原理檢驗直尺刻度實驗.

A straightedge provides a standard of straightness by comparison with which the straightness and flatness of a surface can be inspected . 直邊提供了直線的檢驗標準，即表面的平面度可以與直邊相比較做檢測。

Mathematics To draw (a geometric figure) that meets specific requirements, usually with instruments limited to a straightedge and compass. 作圖：根據(jù)具體要求畫出（幾何圖形），通常只用直尺和圓規(guī)工具
