求翻译：当有必要扭转对齐，最好的设计由简单的横向曲线，相隔一个足够长的直线，它们之间，全部实现超高。另外，简单的曲线可以分离同等长度的螺旋。是什么意思？

When it is necessary to reverse the alignment, the best design by a simple horizontal curves, separated by a long enough straight line between them, all to achieve ultra-high. In addition, a simple curve can be separated from the spiral of the same length.

When it is necessary to reverse the best alignment, design a simple horizontal curves, a long enough interval between the straight line between them, and to super-high. In addition, a simple curve can be separated an equal length of the helix.

When has the essential reverse to uneven, the best design by the simple crosswise curve, is separated by an enough long straight line, between them, realizes the superelevation completely.Moreover, the simple curve may separate the same level length the screw.

When there is a need to reverse the alignment, the best design by simple transverse curve, separated by a line long enough between them, all super high. In addition, simple curves to separate spiral of equal length.
