摘　　要：应用最小二乘支持向量机建立了Al2O3粒子衰减特性预测模型,引入微粒群算法解决了模型多参数优化问题,结合辐射传输数值求解方法获得了吸收散射性介质的红外辐射特性。比较结果表明,该方法具有较好的预测能力,在保证模拟结果精度的同时提高了运算速度。A prediction model for extinction property of Al2O3 particle was established by using least square support vector machine. Particle swarm optimization method was applied to optimize the multi-parameters. Combined with the numerical method for radiative heat transfer, the infrared properties of emitting and scattering medium were obtained. The result shows that the method is capable to predict the extinction property accurately meanwhile the operation rate has great enhancement.
