摘　　要：在对作者原有工作改进的基础上，应用自行研制的“光纤探针深度计”首次精确测定了Kr+紫激光406．7～415．4um和He-Ne激光632．8nm波长处新鲜离休人肺组织中光能流率分布，获得这两种重要波长处人肺正常组织和人肺腺鳞癌组织中光能流率的分布规律及光穿透深度的数值：（1）δnormal=0.08mm,δtumour=0.32mm(λ=406.7～415.4nm);(2)δnormal=1.19mm,δturmour=1.70mm(λ=632.8nm),并对现有人肺组织的光穿透深度数据作了总结和讨论．Using the device of depthometer with fiber-optic probe located in biotissue developed by ourselves,we have accurately measured fluence rate distributions in fresh human lung tissues (normal and adeno-squamous carcinoma)in vitro at 4O6. 7~4l5. 4nm of Kr+ laser and 632. 8nm of He-Ne laser for the first time. We thus determined the values of optical penetration depths of human lung tissues by fitting experimental results of fluence rate distributions with mono - exponential functions. The result is: (1)δnormal= 0. 08mm,δtumour= 0.32mmat406. 7~ 415. 4nm, and (2 )δnormal=1. 19mm, δtumour =1. 70mm at 632. 8nm.
