本文用计算机数值模拟求得了激光辐照时生物组织中的一维温度场和相间边界移动速率 ,进而估计了其热损伤大小和烧蚀组织数量 ,并对热损伤区大小和切割深度进行了实验检验。结果表明 :该估算结果与实验数据符合得很好。 In this paper, the one-dimensional temperature field and the moving speed of the boundary between the laser beam and the laser beam were calculated by computer numerical simulation. Then the size of the thermal damage and the number of the ablated tissue were estimated, and the size of the thermal damage zone and the depth of cut test. The results show that the estimation results are in good agreement with the experimental data.
