目的：观察粘合剂对激光血管吻合的耐压强度与抗拉强度等力学特性的影响。
AIM: to observe the effect of binding on the mechanical characteristics of bursting pressure and tensile strength after laser vascular anastomosis with binding.
与抗拉强度相比，实验得到的花岗岩弹性模量数据比较离散，但变化幅度不大。
Compared with the strength, the elastic moduli of the granite are scatter and change slightly with the increasing loading rate.
同时进行了层面劈拉试验，并比较了层面I型断裂特性与抗拉强度特性之间的规律。
At the same time, splitting tensile experiment of layer surfaces was performed, and variation of characteristics of mode I fracture and tensile strength was compared.
