【摘要】：内混合气溶胶粒子的有效吸收对激光大气传输有着不利影响。以黑碳和氯化钠两种典型成分为例,计算了密度和比热相同情况下,均匀球和分层球模型粒子的有效吸收系数。研究结果表明:有效吸收系数大小与粒子组分混合方式有关。在粒子吸收热量加热大气过程中,黑碳为核的粒子在可见光和近红外波段有效吸收系数更大;均匀球粒子在中红外波段和远红外波段(100μs后)有效吸收系数更大,而氯化钠为核的粒子在远红外波段(前100μs)有效吸收系数最大。
[Abstract]:The effective absorption of inner mixed aerosol particles has a negative effect on laser atmospheric transport. Taking two typical components of black carbon and sodium chloride as examples, the density and specific heat are calculated. The results show that the effective absorption coefficient is related to the mixing mode of particle composition. The effective absorption coefficient of black carbon particles in visible and near infrared bands is higher. The effective absorption coefficients of homogeneous spherical particles in the mid-infrared and far-infrared bands were higher than those in the far-infrared band, while the effective absorption coefficients of the particles with sodium chloride as the nucleus were the largest in the far-infrared band (the first 100 渭 s).
