摘　　要：首先分析了近红外光在均匀生物组织中的传播过程,在此基础上提出一种计算分层生物组织表面漫反射率的理论模型。利用这种理论模型,讨论了两种不同组成的生物组织的表面漫反射率,得到双层介质表面漫反射率随探测距离的变化趋势与其他文献报道的研究结果一致。Based on the analysis of the transmission of near infrared light in homogeneous tissues, a calculating method of diffuse reflection ratio (DRR) for layered tissue is presented. According to this method, the DRRs of two layers of tissues were calculated, which were consistent with former literatures. By use of this theoretical model, DRRs of two kinds of tissue with different structures are discussed. It shows that DRR of two-layered medium varies with detecting separation in the same tendency with that of former literature.
