【摘要】：內(nèi)混合氣溶膠粒子的有效吸收對(duì)激光大氣傳輸有著不利影響。以黑碳和氯化鈉兩種典型成分為例,計(jì)算了密度和比熱相同情況下,均勻球和分層球模型粒子的有效吸收系數(shù)。研究結(jié)果表明:有效吸收系數(shù)大小與粒子組分混合方式有關(guān)。在粒子吸收熱量加熱大氣過(guò)程中,黑碳為核的粒子在可見(jiàn)光和近紅外波段有效吸收系數(shù)更大;均勻球粒子在中紅外波段和遠(yuǎn)紅外波段(100μs后)有效吸收系數(shù)更大,而氯化鈉為核的粒子在遠(yuǎn)紅外波段(前100μs)有效吸收系數(shù)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).
