主　　题：non-spherical aggregates biological particle random orientation extinction characteristics 

摘      要：In this study,a method was presented to accurately obtain the extinction characteristics of the non-spherical biological particle *** on the multi-sphere particle model of non-spherical particles,a randomly oriented aggregation model was firstly built to construct the *** discrete-dipole approximation method was used to calculate the extinction characteristics of aggregates in the 3–14 μm *** average mass extinction coefficients of three materials are 0.802 m~2/g,0.907 m~2/g,and 0.866 m~2/g in the 3–5 μm waveband and 0.590 m~2/g,0.402 m~2/g,and 0.523 m~2/g in the8–14 μm band,*** chamber experimental results are in good agreement with theoretical analyses.
