Repetition of Concentric Circles and Semicircles

An Art Deco geometry composed of circles. Several concentric rings or layered semicircles are arranged at regular intervals, with precise perfect circular lines of consistent width; it might be a brass ring around a circular mirror, a cornice composed of repeated semicircles, or a circular pattern on a carpet. The center of the circles aligns with the spatial axis. Avoid: using ellipses and irregular circles, uneven spacing of rings, making the circles into organic teardrop shapes, letting the center of the circles deviate from the axis of symmetry.

一組以圓構成的裝飾藝術幾何。數個同心的圓環或層層疊起的半圓以規則的間距排列,線條是精準的正圓,寬度一致;它可能是一面圓鏡外的一圈黃銅環、一道由半圓重複組成的簷口、或是地毯上的圓形圖案。圓的中心對齊空間的軸線。避免:使用橢圓與不規則的圓、讓圓環的間距不均、把圓做成有機的水滴狀、讓圓的中心偏離對稱軸。
