但是将石墨单原子层冷却到接近绝对零度时，不可思议的事情发生了：电子的速度得到显著增加。
But cool this graphene down to near absolute zero and something extraordinary happens: the electrons speed up dramatically.
应用该方法可以减少粗加工余量，提高粗加工精度和速度，提高了层切法模具零件数控粗加工效率。
By this method the accuracy and speed of the rough cutting processing can be improved. The efficiency of the die adaptive nc rough machining based on stratifying method is increased.
