<P>怎么您这里同时考查镜面对称和中心对称的？我学过的一点点皮毛知识不够用了。<IMG alt="" src="http://bbs.mf8-china.com/images/smilies/default/mad.gif" border=0 smilieid="11"> <IMG alt="" src="http://bbs.mf8-china.com/images/smilies/default/sweat.gif" border=0 smilieid="10"> </P>

<BR>&nbsp; <BR>&nbsp; <BR>&nbsp;&nbsp;&nbsp; 非常正确！<BR>&nbsp; <BR>&nbsp;&nbsp;&nbsp; 判断 正六面体自镜像魔方 的最简单的方法： 代入类似下面两个公式，如果该魔方<BR>是“正六面体自镜像魔方”，则“相关所有块 能 同时到达其关于 几何中心 对称的块 <BR>的位置！”&nbsp; 从而 为她正名 －－－“正六面体自镜像魔方” ！<BR>&nbsp; <BR>&nbsp;
