1·Instead of specifying the data for the gauge (or graph), I actually build the gauge out of graphics primitives such as circles, arcs, and rectangles.
实际上，我是用圆、弧和矩形之类的基本图形构建仪表盘的，而没有通过为仪表盘(或图形)指定数据的方式。
2·So-called arc node lists contain arcs and nodes.
所谓的弧节点列表包含弧和节点。
3·As a result, multiple images of these background galaxies are distorted into long faint arcs — a simple lensing effect analogous to viewing distant street lamps through a glass of wine.
结果是这些背景星系的多重影像被扭曲成长而暗的弧——透镜效应的例子，类似于透过酒瓶底的玻璃看远处的街灯。
4·The DXF and DWG file formats also support arcs and circles, which you can approximate in your output formats by creating multiple small line segments approximating the circle or arc.
DXF和DWG文件格式还支持弧和圆，您可以在输出格式中通过创建多个小线段来近似模拟圆或弧。
5·To get the idea of an extended link with many arcs, think of a link from a download site with mirrors.
要了解具有许多弧的扩展链接，请考虑来自镜像下载站点的链接。
