魔方【十字天】三阶十字教程 CROSS十字教程【十字天书】(白底版) 我们在初学魔方的时候,做十字的方法是依次将四个底层棱块(指构成十字的四个带底色的棱块,以下简称棱块)调整到正确的位置。这是一种容易理解,也容易掌握的方法。要想用这种方法快速完成十字,就需要对单一棱块的各种状态快速反应出简单且顺手的步骤将其还原,下面举几个例子: R’ F R R’ u’ R / R u R’ R u’ R / R’ u R’ 因为不能破坏已做好的棱块,所以每次调整好一个棱块需要2~3步,一共平均要8~12步,步数过长。而且做一个棱块的过程中很难兼顾其他棱块,常见做法是做好一个棱块再看下一个,这样先后停顿3次,不仅十字速度很慢,而且开始的15秒钟观察也得不到有效利用。 假如一个棱块恰好在正确位置,我们就会先入为主,以它为起点,结果就是被误导,举一个最简单的例子: 将魔方还原好,顶色朝上,做R’ D R。 这时候只有R面的棱块是正确的,那么我们依次还原每个棱块的话,大概最佳步骤是这样: R U R’ F2 做好F面的棱块 U L2 做好L面的棱块 U B2 做好B面的棱块 一共八步,通过优化手法是可以很快做完,但是我们通过逆转打乱公式知道只要做R’D’R就可以做好十字了,问题就在于我们一切的思考都以R面棱块是正确的为出发点,而实际上我们被R面棱块正确这一现象给误导了。 今天要教给大家的做十字方法是充分利用15秒的观察时间,建立棱块的正确相对位置关系,然后再进行最终调整,在调整过程中观察第一组F2L,总步数不超过8步。 【忘】 首先不要被已经位置正确的棱块误导,因为现在看来正确的棱块可能在相对位置关系中恰恰是不正确的,会对我们思考产生误导。所以我们第一步要做的,就是对当前中心块的颜色视而不见,把它们忘掉,如果做不到,你可以在练习十字时将四个侧面的中心块盖子去掉。 除了中心块的颜色要忘掉外,不要被四个底层棱块外的任何块吸引注意力,比如两个连在一起的角块和棱块之类,因为在思考和完成十字过程中,这些信息起不到任何作用,接收、记忆和思考这些信息只会浪费我们宝贵的思考时间,或者对我们的思考过程产生干扰。 在一团杂乱无章的色块中迅速筛选出有价值的信息,并据此迅速作出判断和行动,这就是提升十字时间乃至提升整体还原时间的要领之所在。 过滤后的有效信息(这个理解就好,哪个底都一观察到的全部信息 样) 『要求』 are no special instructions below, in this report, the "I" mean green town in yingde city middle school, "we" means young qingtang town middle school in the Township of yingde city middle school teachers ' professional development study group. ) The actual condition and the specific situation of young teachers ' professional development for young teachers ' College ...
