【Abstract】 The KBr press slice was used to study the optical properties of calcic group minerals,char and fly ash in experiments.The radiative properties of calcic group minerals are analyzed by the Mie theory.At the same time three kinds of raditive computational models of unburned char were constructed according to its structural model based on the Mie theory,ash coated model and equivalent optical constant theory,and the radiative parameters of different unburned chars were calculated.The results were verified in experiments.更多还原
