关于如何掌握好F2L技巧

selfly

<P>其实要学好F2L并不难，重要的是要理解F2L，只要花一点心思F2L sub30不是没有可能的</P>
<P>如果F2L可以sub20那么进40不成问题sub16进30sub25没有问题</P>
<P>因为我惯用左手……所以一直受到公式的限制，镜象又觉得不顺手，只可以自己研究F2L</P>
<P>这是我一直自研究F2L得出的结论——利用好空档</P>

<P>大部分F2L都利用了这个原理，只要明白这个原理F2L其实非常容易理解，</P>
<P>说到底 就是在下两层完整的情况下组合一个1x2x1的小方块</P>
<P></P>
<P><FONT color=blue>例子二(利用FR空档)</FONT></P>
<P><FONT color=red>注意看上面一个角和棱边的动向</FONT></P>
<P>所有的F2L都不过是利用某个空档组成这个1X2X1的小方块，然后将它插入到正确的空档上，我们来看更多的例子...</P>

<p>上面的可以慢慢的去理解，毕竟一口吃不成胖子~(- -~)</p>
<p>如果你已经熟练了上面这些，你应该去练习观察了，Good luck......</P>

顶一下。总结的不错，不过感觉这样的帖子有很多，规律性都很强呀。 但是按LZ的方式做的话。感觉有些公式不是很顺手呀。

因为是自己推倒出来，如果仍然是自己来写公式的话自然会不顺手。但我没有写过一条关于F2L的公式，看到情况，马上反应，我不觉得不顺手……
可能只是你解决的方法不是太顺手吧- -
上面的JAVA是因为F这面对着我。。所以我写的JAVA里有F，
干脆将图的F那面看为R或L吧~

我左手还算灵活…所以我的镜像公式都没背…

恩收藏了，等什么时候想学再来看看 ，太懒了

kexin_xiao

LZ很认真，帮你顶一个！

yjw44

我也来顶一个,收藏了!!

宇枫 幽蓝

很可以，但LZ的一些F2L不是最简的，而且有些不顺。象最后两图，很不好。讲了那么多，大概理论还是很不错的。顶了

魔鱼儿

楼主辛苦了,呵呵,顶下,总结的不错

java显示不了～～怎么办？？
