本实验用Ｈｅ－Ｎｅ激光照射大鼠烫伤创面促进其愈合，同时测定了愈合过程中创面对Ｈｅ－Ｎｅ激光的反射率。结果表明：在整个愈合过程中其反射率呈现先迅速下降，而后缓慢上升的变化趋势。反射率变化的幅度与剂量无关而变化的平均速率与剂量有关。
In this experiment, He-Ne laser irradiation scalded wounds to promote healing, and measured the healing process of He-Ne laser reflectivity of the wound. The results showed that the reflectivity of the whole process of healing decreased rapidly and then slowly increased. The rate of change in reflectivity is independent of dose and the average rate of change is dose dependent.
