Colure

[kә'ljuә]

解释:

(n.) One of two great circles intersecting at right angles in the poles of the equator. One of them passes through the equinoctial points, and hence is denominated the equinoctial colure; the other intersects the equator at the distance of 90¡ from the former, and is called the solstitial colure.
