查询词典 laser

Results Using two methods, i.e., the mathematical simulation and las er surgery experiment the depth of thermal damage induced by laser irradiation i n biological tissues was determined. The CO2 laser power output was 1.50 W, 3 .15 W and 8.01 W, respectively, and irradiation time was 9-20 s. The avera ge value of relative deviation which represents the departure of the numerical s olution from the experimental result was 3.60%.
