In this paper, we proved that there exists only one contact point between a pair of non-circular gears working under the designed pitch curves when they are manufactured by involute cylindrical gear cutter in numeric control slotting machine. Under this manufacturing condition, the pair of non-circular gears can mesh accurately.

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.
Live Map和Google Map都使用墨卡托投影,但并不像人们认为的那样他们使用WGS84基准面,虽然你在他们的API中输入的值是WGS84下的值。【译注:原因是WGS84基准面是基于椭球面的,而LiveMap和GoogleMap使用的是球面。另外,YahooMap使用的是等距圆柱投影。
