We'd know it for any of the coordinate planes.

对于任意坐标平面，都应该知道怎么做。

Difference between the angles of edge projections and the angles of the intersections of surfaces and coordinate planes are raised in this paper.

同时区分了刀刃在坐标平面上的投影角和刀面相对坐标平面的倾斜角，并用实例计算说明这两种角度有时差值较大。

And, in terms of a graph, they correspond to slicing by a plane that's parallel to one of the coordinate planes, so that we either keep x constant, or keep y constant.

从图像上看，它们对应于,用平行于坐标轴的平面横截图像得到的，过程中保持x或y恒定。

Some big hub airports, like Dallas, Atlanta and Houston, do coordinate regularly with outlying airports used for diversions, setting capacity limits, for example, of how many planes each can take.

ADS-B promises to make air traffic control easier, cheaper and in many ways safer by allowing planes to transmit their locations by radio frequency instead of depending on towers to use radar to track and coordinate them.
