我准备研究这个转盘。

转盘转动后它的数字方向就反了，看起来就不舒服了，或理解为未完全复原。是否有这样的现象发生？

金优的这个想法很有创新意义的。

在有数字的圆形面的基础上改成椭圆形，只要那椭圆形长的那个方向大于轨道的宽度，就可让数字不会随意转动，玩的过程中椭圆形上的数字只会出现正反两个方向。这样会提高转盘的复原难度。不要小看这样的改动，其难度提高不止是两倍啊！我没研究过这转盘所以算不出来，估计难度提高１０倍都很有可能的[em06]

那还不如索性改为矩形，即每个子改成“滑块”（或许其四个角要有点倒角）。这样的话，情况将如何，我还未玩过，慢慢再说。

智力数字转盘数字方向是否复原初初探

随意弄了个例子，那样限制了各个子的自转之后，排序完成了，数字方向也没倒的。但一个例子不说明问题，多个例子也无说服力。哪位朋友从理论上探讨一下，何时倒？何时不倒？还是永远不倒？

设原来1～20次序排好且都是“正向”——各子的数字之底部朝向“大盘中心”为正向，反之为反向。下文中1表示正向，1’表示反向，等等。

本楼乱得难以辨认，没本事修理了。关于数字方向正倒问题不看也罢。
