Abstract A multiwavelength and multiangle mathematical model (MWMA) is developed, and the corresponding influence factors of the model are analysed by the numerical calculation. Combined with measurement data of radiation flux and the curve in theoretical calculation, particle sizes of different materials can be obtained. It is found that smoke particle size gradually decreases from land plaster, cotton wick, beech wood, polyurethane, sandalwood, decahydronaphthalene, to N-heptane.
