利用ＭｏｎｔｅＣａｒｌｏ方法模拟了光在两层具有不同光学参数的组织中的传输。详细讨论了组织间的吸收系数、有效散射系数和各向异性因子ｇ的差异对漫反射率、漫透射率和光强的纵向分布的影响，分析了光强分布变化的原因
The Monte Carlo method is used to simulate the transmission of light in two layers of tissue with different optical parameters. The influence of inter-organizational absorption coefficient, effective scattering coefficient and anisotropy factor g on the longitudinal distribution of diffuse reflectance, diffuse transmittance and light intensity is discussed in detail. The reason for the change of light intensity distribution is analyzed
