架十字的一小点技巧

架十字的又一小点技巧：

you must figure out ways to accomplish multiple things with one move. （一次做好多个或为后面的做准备，同时考虑相相邻两个棱很有效）Here are a few tips for shortening your cross:
- Do the wrong move. For example, if doing R would place an edge, but doing R' would make it easy to place another edge in it's correct slot, then make the 2nd edge easy to place by doing R' and then do R2 to place the first edge after placing the 2nd.
- If putting two edges in the wrong slot makes it easy to place the 3rd and 4th edges, then do that so once all the edges are in their correct position in relation to each other, then rotate that face CW or CC to get them lined up

哇 好多牛人啊~~~~~~~~

好复杂呀                  
唉

延延啊

看不懂啊..................

3楼我对第二条的理解看来也有误。是不是如下图的例子，先不急于做D2以复原红黄和红蓝棱，而是先做B'使红白棱处于红黄棱的对面，再做R'使红绿棱处于红蓝棱的对面，最后做D2使底层的十字整体到位（对准四个侧面中心块）。

我把6楼介绍的改为目前常用的配色，并试着解释如下：

4楼说：“我来举一个具体例子：将还原好的魔方底层朝上做以下步骤打乱：R2 F R

可以看到，如上打乱后只要做R就可以还原一个棱块（即魔方顶层右边的棱块），但是如果先做R'就能让另一个棱（即魔方顶层靠近你这边的棱块）容易还原，那么就先做R'F 来还原第二个棱，再做R2来还原第一个棱。”

其中的“R'F ”是不是应为“R'F' ”？

第一句实例如http://bbs.mf8-china.com/dispbbs.asp?boardID=2&ID=2273&page=1中第二个图的右上角的小图 F‘ R F R2  中 的“ R F R2 ”

做相反的步骤。例如：如果做R能够还原一个棱，但是做R'能够让另一个棱更容易的到它的正确位置，那么先做R'让第二个棱块更容易还原，还原第二棱后再做R2来还原第一个棱。

我来举一个具体例子：将还原好的魔方底层朝上做以下步骤打乱：R2 F R

??这个很容易看出来的啊。

那第二句是什么意思呢？

edge 即 edge piece——棱块

2nd edge 不是指第二层的棱块，而是指区别于棱1的另一个棱块——棱2
我来翻译一下第一条：

- Do the wrong move. For example, if doing R would place an edge, but doing R' would make it easy to place another edge in it's correct slot, then make the 2nd edge easy to place by doing R' and then do R2 to place the first edge after placing the 2nd.
