The two fields are experimentally confirmed to correspond to the smooth region and the shear lip on the fractureface respectively.
有限元计算和实验测定结果证实了这两部分分别与试样断口上的纤维区及剪切唇相对应。

The loss are divided into the loss by the changing of fracture width and the loss from fractureface to matrix, and the loss model of working fluid is established.
Moreover, the acid will further etch the fractureface and create deeper channels which leads to high fracture conductivity and better treatment effect even under high closure stress.
