1·As to the common perpendicular plane of the two planes, some discussionis made in detail.
关于两平面的公垂平面，也作了详细的说明和论证。
2·When bouncing your flash, at certain angles close to that perpendicular plane, direct light will hit your subject.
当使用跳灯时，即使闪光灯以接近垂直的角度向上方打光，但仍有扩散的光线直接照射到被摄体上。
3·The first step of the migration is performed within the perpendicular plane, and the second step of migration is the spatial migration of the side waves.
第一步偏移的实质是在铅垂平面内完成偏移归位，第二步偏移是在空间内完成侧面波的空间归位。
4·Or add transparent graphics with computed transparencies perpendicular to the Earth plane to create a more realistic layered effect for all viewing angles.
或者，添加与地平面垂直的、计算出透明度的透明图形，创建针对所有视角的更真实的分层效果。
5·A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting in rings nearly perpendicular to the plane of the galactic disk.
极环星系是种稀有的星系类型，它们有着几乎和银盘平面垂直，呈环形公转的大量的恒星、气体和星尘。
6·Now, if it's perpendicular to the plane, then in that case, it's perpendicular to the blackboard.
如果它垂直于这个平面，在那个例子里，它垂直于黑板。
7·Being perpendicular to the surface means that you are perpendicular to its tangent plane.
垂直于曲面也意味着垂直于它的切平面，垂直于曲面也意味着垂直于它的切平面。
8·So it's still perpendicular to the same plane.
所以这个外积还是垂直于同一个平面。
9·So, how do we find this vector that's perpendicular to the plane?
所以，我们要怎么找，垂直于这个平面的向量？
10·In other words, it's perpendicular to the plane of the two vectors.
换句话说，它垂直于，两个向量所处的平面。
