Helli: ok! Say no more... I would also have woken up at the crack of dawn to get to the bathroom first!
知道了！无须多说…那样的话如果我需要第一个进浴室也得在破晓时分起床了！
Consequently, at the macroscopic crack branching velocity, the experimental fracture surface energy and the fracture surface roughness; have no single value in such materials.
因此，对这种材料在宏观裂纹分叉速度时，实验断裂表面能及断裂表面韧性没有单一值。
