摘　　要：用氦氖激光照射乌珠穆沁和萨力斯克公羊的离体精液,四个处理组的辐射能量密度分别为0.89、2.22、7.09和26.60 J/cm^2。结果表明,氦氖激光能提高绵羊精子活率,中、小剂量的激光能延长精子存活时问,提高存活指数,结果还预示激光能暂时增强精子的细胞通透性。Wuzhumuqin and Salisike rams' semen was in vitro irradiated with He—Ne laser,the energy density in 4 treatments being 0.89,2.22,7.09 and 26.60 J/cm^2,respectively.It wasshown in the result that He—Ne laser can increase rams'sperm motility,and that a lower ormedium dose of laser can prolong their survival time and increase their survival index.It wasalso suggested that spermic cell permeability be improved immediately after laser irradiation.
