标题: 请问关于层先法的第三层的棱块 [打印本页]

作者: william_khs    时间: 2008-7-5 14:15:58     标题: 请问关于层先法的第三层的棱块

<P>第三层的棱块,假如是相临面颜色不同(请问 图1),可以用公式 "<SPAN lang=EN-US style="FONT-SIZE: 12pt; FONT-FAMILY: 'Calibri','sans-serif'; mso-bidi-font-size: 11.0pt; mso-fareast-font-family: SimSun; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"><FONT color=#000000>R ( U’2 R’ U’ )<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>R ( U’ R’ U’ )</FONT></SPAN>"</P>
<P>但是,假如是相对面颜色不同,可以用什么方法? ( 除了用 " <SPAN lang=EN-US style="FONT-SIZE: 12pt; FONT-FAMILY: 'Calibri','sans-serif'; mso-bidi-font-size: 11.0pt; mso-fareast-font-family: SimSun; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"><FONT color=#000000>R ( U’2 R’ U’ )<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>R ( U’ R’ U’ ) </FONT></SPAN>" 这条公式两次 )</P>

这个公式主要是翻角色的吧,跟棱块关系不大(移动了棱块应该属于副作用)

建好十字以后,主要是运用OLL21-27对角块,然后再用PLL复原

是 OLL公式吧 只要頂面顏色一致就好了啊  , 棱塊等PLL公式的時候再調整

没看懂说的什么,好象说的的是PLL中的棱换,能在具体点不

乌木整了一大堆PLL,强调对棱换,故意忽视了角的变化。我看楼主需要的就是:r2R'2Ur2R'2U2r2R'2Ur2R'2。
作者: william_khs    时间: 2008-7-5 18:57:10

谢谢了....不过看来还是用我帖出来的公式两次较方便~~~~~~但还是那句,谢谢各位(尤其是乌木前辈)

<P>哈,不是我不管角块,而是1楼的角块涂成灰色,按惯例就是表示不管角块。</P>
<P>&nbsp;</P>
<P>此外,你的r2R'2Ur2R'2U2r2R'2Ur2R'2是两个对棱互换,所以如果不管角块的话,要两个对棱互换,也可以简单地做U2即可;要不动角块的话,就可以做r2R'2Ur2R'2U2r2R'2Ur2R'2 。</P>

当然可以。不过能熟悉上面说的那第三式<SPAN lang=EN-US style="FONT-SIZE: 10.5pt; FONT-FAMILY: BatangChe; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"><?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><v:shapetype coordsize="21600,21600" o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f"><FONT face=宋体 color=#000000><SPAN lang=EN-US style="FONT-SIZE: 10.5pt; FONT-FAMILY: BatangChe; mso-bidi-font-family: Arial; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA">U R2 U'R2 D B2 L2 U L2 D'B2 (前后棱块互换及后左、后右角块互换<FONT face=宋体>)</FONT></SPAN></FONT></v:shapetype></SPAN>的话,以后玩四阶时处理四阶的特殊情况很有用的。

楼主的问题着实看不懂,用一次公式会使三个棱块产生位置变化,而不是相临的两个面。用完两次又还原了,跟你的问题完全不是一回事。
作者: 乌木    时间: 2008-7-5 20:43:53     标题: 回复 12# 的帖子

<P>他是不管角块。此外,他说的用三次同一公式之间要调换魔方的方位(应是三次邻棱互换,结果成为两个对棱互换)。</P>

你说的对,其实层先主要就是两个公式就可以完成OLL
