摘　　要：求两曲面围成的立体在坐标面上投影时,经常误以为两曲面的交线在坐标面上的投影曲线所围成的区域即为立体在相应坐标面上的投影。对一道典型的求立体在坐标面上的投影问题进行解析,指出易错之处,进而给出一种求立体在坐标面上的投影时不易出错的做法。To get the projection of a stereo surrounded by two surface on the coordinate plane,often the surrounded area by projection curve of intersecting line of two curved surfaces on the coordinate plane is mistaken for the projection of the stereo.Here we analyze a typical problem about the stereo projection on the coordinate plane to point out the right answer,and gives a general solution to solve this kind of stereo projection problem on coordinate plane.
