只有在平坦的宇宙中，空间才符合标准的几何规律——三角形的内角和精确地等于180度，平行线永远不相交。
Only in a flat universe does space obey all the standard geometry-class rules-the angles of a triangle add up to exactly 180 degrees and parallel lines never meet.
Barham的实现仅在一个小的集合中(字母数字加一些其它字符)查看相对较短和不相交(disjoint)的字符序列。
Barham's implementation simply looks for relatively short, disjoint sequences of characters in a small set (alphanumeric plus a few others).
而交错轴斜齿轮传动由于其可以传递既不平行又不相交的两轴之间的运动和动力而被广泛地应用。
And the transmission of cross helical gear can transmit because of their sport of crossing two axles and power widely application neither parallel nor intersect.
