<p>不好意思，<br/>推荐给你另一种方法试试：<br/><a href="http://www.rubik.com.cn">http://www.rubik.com.cn</a></p><p>你说的这个方法好像比较费解。</p>

<p>楼主所引的教程是否魔方吧主页的魔方教室里的？是哪个教程？</p><p>且不管它，请看下面的java动画（请用最右边的按钮逐步逐步看其动作），把第三层改为左片，先用公式九顺时针翻正红蓝黄角，再转动左片把红蓝白角放到上左后方位，用公式十把它逆时针翻正。最后把魔方的左片转回。</p><p>若有两个对角要翻正，则如右图所示。</p><p>我想那教程的意思应该就是这样，供您参考。</p><p>此外，凡同一角同方向连翻二次等于该角反方向翻一次，由此可以解决要求翻正三个角的情况（当然也可用另外的公式翻三个角）。</p><p>&nbsp;<applet codebase="3" height="250" width="250" code="RubikPlayer.class"><param value="SupersetENG" name="scrptLanguage"/><param value="U R U' R' U R U' R'  L' R U R' U' R U R' U' L " name="scrpt"/><param value="5,0,0,0,0,0,0,0,0" name="stickersFront"/><param value="3,3,5,3,3,3,3,3,3" name="stickersBack"/><param value="3,4,0,4,4,4,4,4,4" name="stickersLeft"/><param value="4,5,5,5,5,5,4,5,5" name="stickersUp"/></applet><applet codebase="3" height="250" width="250" code="RubikPlayer.class"><param value="SupersetENG" name="scrptLanguage"/><param value="U R U' R' U R U' R' L2  R U R' U' R U R' U'  L2 " name="scrpt"/><param value="0,0,0,0,0,0,4,0,0" name="stickersFront"/><param value="0,2,2,2,2,2,2,2,2" name="stickersDown"/><param value="3,3,5,3,3,3,3,3,3" name="stickersBack"/><param value="3,4,4,4,4,4,4,4,2" name="stickersLeft"/><param value="4,5,5,5,5,5,5,5,5" name="stickersUp"/></applet></p>

<p>楼上说的“此外，凡同一角同方向连翻二次等于该角反方向翻一次，由此可以解决要求翻正三个角的情况（当然也可用另外的公式翻三个角）。”不妥，改为：</p><p>如果左片有三个角要翻正（三个顺翻或三个逆翻），请思考该如何做。</p><p>最好您学一下发个java图演示翻三个角。请见<a href="http://www.mf8.com.cn/Java/ShowArticle.asp?ArticleID=1">http://www.mf8.com.cn/Java/ShowArticle.asp?ArticleID=1</a>，在“回复”或“编辑”窗口中贴了java图的代码后，还要点击“Design”，编排好文字和图画，再可以“发表”。</p><p>或者请您暂时先把下图的复原步骤贴出来（图中白色算F面，绿色为R面，等等），我帮您看看做得对不对：<br/><br/> <br/></p><p>此外，java图可以用鼠标右键拖着翻滚观察。</p>
