冷态实验结果表明：流化床内同一高度截面与基准面之间的压差是随风量的增加而增加的，但是风量过于增大反而使同一高度截面与基准面之间的压差减小了，同时，压差是随初始物料量的增加而逐渐增加的；在同一高度截面上，颗粒平均浓度随风量的增大而逐渐减小的，随物料量的逐渐增大而增大的；颗粒浓度分布的不均匀性随风量的增大而逐渐减小，而随物料量的增加而不断增大的。

Based on the above-mentioned parameter, according to the relationship between robust estimation and nonlinear diffusion, the Turkey loss function is introduced as the diffusion function in SAR image decomposition because of its better performance, and the contour of an image is extracted by the Turkey diffusion function with the proposed diffusion parameter mentioned above. The experiment results indicate that the Turkey loss function based diffusion process can strengthen the conspicuous contour. Additionally, a Raita\'s criterion-based method, solving the automatic diffusion threshold, is proposed to automatically set the threshold in diffusion decomposition.
