摘　　要：目的　探讨激光照射对NaCl溶液、葡萄糖溶液、蒸馏水、自来水及酒精粘度的影响。方法　用He Ne激光对液体进行不同时间的照射 ,以奥氏粘度计采用比较法对液体的粘度进行测量。结果　葡萄糖溶液、NaCl溶液、蒸馏水和酒精的粘度随激光照射时间的增加而减小 ,其中葡萄糖溶液的粘度改变较明显。而自来水经激光照射后 ,粘度随激光照射时间不同出现双向结果 :照射在 10min以内 ,粘度比无激光照射时要低 ;照射时间为 15min以上时 ,粘度较无激光照射时要高。结论　液体的粘度不但与液体的性质有关 ,而且与激光照射时间有关。Objective: To probe into the effect of laser radiation on the viscosity of NaCl solution, glucose solution, distilled water, tapwater and alcohol. Methods: The radiation of He-Ne laser was applied to the liquids for different periods; Ubbohbe's viscosimeter was used to measure the viscosity of liquids by comparison. Results: The viscosity of glucose solution, NaCl solution, distilled water and alcohol decreased with the increase in the radiation time of laser, and the viscosity change of glucose solution is relatively significant. However, the viscosity of tap water varied in different periods of laser radiation. When the time was within 10 minutes, the viscosity was lower than that where there was no radiation of laser. When the time was 15 minutes, the viscosity was higher. Conclusion: The viscosity of liquids is related not only to the radiation time, but also the nature of the liquids.
