本试验以昆明小鼠1-细胞期胚胎为实验对象，以CZB培养液为基础液在不同发育阶段添加外源性ROS，培养至桑椹胚、早期囊胚、囊胚、扩张囊胚阶段，分别观察胚胎的胚细胞数、分裂指数的变化。

It indicates that the damnification morphology of K9 glass is cleavage damage, the reason of which is that the hoop tensile stress overtops materials'tensile strength. And the materials'damage threshold is inversely proportional to irradiation time.The mathematical model of in-band CW laser irradiating optical material is established.

结果表明：K9玻璃材料的损伤形态为解理破坏，破坏的原因是环向拉伸应力大于材料的抗拉强度，且材料的损伤阈值与辐照时间反向相关，即激光功率密度越高，造成破坏所需的时间越短。
