菜鸟也谈F2L之“脱菜版”

<P>另外: </P>
<P>我整理了一份<BR>《“初学者/久学不会者”的总结性教程》</P>
<P>为了免去你留下信箱的麻烦，<BR>你只要给我的信箱（<A href="mailto:myrubiks@gmail.com">myrubiks@gmail.com</A>）<BR>发一封信，我会立刻把以下我收集到的<BR>几个教程完整的发给你(5分钟内)。</P>
<P>&nbsp;</P>
<P>1. Levopat的三阶魔方七步解法<BR>2. 三阶魔方复原之速成法(新)<BR>3. 三阶魔方复原之角先法<BR>4. 三阶魔方复原之层先法<BR>5. 三阶魔方复原之中级方法<BR>6. 三阶魔方复原之高级方法<BR>7. 三阶魔方复原之初级方法<BR></P>
<P>&nbsp;</P>
<P>　　刚学三阶复原的那会儿，用的是层先法，层先法里面提到了3个F2L公式。使用这3个公式的前提是先要完成第一面的4个角。</P>
<P>&nbsp;</P>
<P>　　F2L的思想是不用先完成第一层的4个角，直接在第一层架完十字后，一起完成前两层。可见F2L是非常重要的一步，可以说，谁在这里完成得最快，谁就可以更快！</P>
<P>&nbsp;</P>
<P>&nbsp;</P>
<P>　　先来复习层先法中提到的3个F2L公式：</P>

<P>我所采用的配色方案是：下白。</P>
<P>本楼选取以(目标)角块白色面朝上，另一(目标)棱块在顶层，与该角块不相连的情况，共４种，即：</P>
<P>Ｕ１，Ｕ２，V１，V２。</P>
<P>-----------------</P>
<P>U1</P>
<P><IMG src="http://www.myrubiks.com/f2l/i/u1.gif" border=0></P>
<P>U'F'U2 F U'F'U F</P>
<P>步１：先把棱移到侧面颜色所在的面，U'</P>
<P>步２：把棱收起来，Ｆ'</P>
<P>步３：让角与棱相连，Ｕ'</P>
<P>至此角棱相连，就可以很方便的把他们一同归位，如果下面还不明白，请反复学习上面的Ａ１和Ａ２的公式后再来看这一个。</P>
<P>-------------</P>
<P>U2</P>
<P><IMG src="http://www.myrubiks.com/f2l/i/u2.gif" border=0></P>
<P>U R U2 R'U R U'R'</P>
<P>解释同Ｕ１</P>
<P>----------------</P>
<P><IMG src="http://www.myrubiks.com/f2l/i/v1.gif" border=0></P>
<P>V1</P>
<P>U2 R U R'U R U'R'</P>
<P>解释同Ｕ１</P>
<P>------------</P>
<P><IMG src="http://www.myrubiks.com/f2l/i/v2.gif" border=0></P>
<P>V2</P>
<P>U2 F'U'F U'F'U F</P>
<P>解释同Ｕ１</P>
<P>-------------</P>
<P>总结：当（目标）角块的顶面是白色（底面颜色），先将（目标）棱(使用U或U'或U2)移到侧面所在位置，然后把该棱收起来(让待完成的那个空档转到顶层，这样再用Ｕ／Ｕ’／Ｕ２来移动角块时就不会移动目标棱块了)，再使用U或U'或U2使用目标角块和目标棱块连起来，再利用Ａ１，Ａ２的方法把他们都归到自己的目的空档中。</P>

LZ说的都是大实话！ 等待你肯定加精的后续作品完成。

不眨眼

呵呵 8错哈

不过一口气多发了几遍啊 还是网络问题泥

新手用观察的方法和硬记公式的速度是差不多的
