Procedure is presented for studying the coefficient of biological tissue absorption of radiation with the wavelength lambda = 1.06 mkm. The absorption coefficient is determined by the temperature values of biological tissue experimentally measured with thermopairs. The coherent radiation current falls on the surface of biological tissue. A mathematical model is formulated for biological tissue heating with radiation. Solution of Furier equation obtained by means of Green function is given. Using the relationship found, the energy absorbed by the biological tissue was calculated and the absorption coefficient of radiation with lambda - 1.06 mkm was determined. The results were analysed and the error of the obtained values of absorption coefficients of biological tissues under study were determined.
介绍了研究波长为λ = 1.06μm的生物组织辐射吸收系数的程序。吸收系数由用热电偶实验测量的生物组织温度值确定。相干辐射电流照射到生物组织表面。建立了生物组织辐射加热的数学模型。给出了利用格林函数得到的傅里叶方程的解。利用所发现的关系，计算了生物组织吸收的能量，并确定了波长为1.06μm的辐射吸收系数。对结果进行了分析，并确定了所研究生物组织吸收系数所得值的误差。
