摘　　要：从海冰的光学特性出发，利用平行分层大气传输方程加上特定边界条件推导出海冰反射率，厚度及波长三者之间的关系．使用实测数据对其参数进行修正，建立了数学模型．用所建立的数学模型从理论上计算的辽东湾海域不同厚度海冰的反射率值与经过大量实验的结果相对照，证实了计算的海冰反射率是可靠的．同时利用数字计算机编程加快了计算速度，提高了准确度和可靠性，为海冰数值预报奠定了基础．The relation between reflectance,thickness and wavelength of sea ice is derived from its optical properties and transfer equation of parallel layered atmosphere under the special boundary condition. Using the really measured data to revise the model parameters,a mathematical model was established, Utilizing this model,we can calculate theoretically the reflectances of the different thickness of sea ice in Liaoding Gulf and comparaed these reflectances with a vast amount of experimental results to verify the calculated ones being reliable or not. Simultaneously making use of the digital computer to compile program we can speed up the operation rate and increasing the accuracy and reliability. It lays up a foundation for numerical forecast of sea ice.
