摘　　要：利用现代高分子材料科学的研究方法和手段,了解玉米淀粉的粉体综合特性,同时初步探讨微观形态和宏观粉体性能的相关性。结果表明:不同筛目的玉米淀粉的分散度(Ds)随着筛子目数的增加,而逐渐的增加;玉米淀粉的松装密度(Ρa)随着筛子目数的增加,而逐渐的增加;玉米淀粉的振实密度(Pp)随筛子目数的增加而增加;玉米淀粉在甲苯作溶剂时所测的粒径(D)比较小。The universal powder properties and the changes of powder properties of corn starch were studied, and the relativity between microstate and macro-powder properties was discussed by the modemmacromolecule research method. The results indicated that the dispersibility （Ds） of corn starch graduallyincreased with the mesh increasing; generally, the pine installing density （Pa） of corn starch increased with the mesh increasing; The compressive density （Pp） of corn starch increased with the mesh increasing. The diameterof the corn starch dispersed in toluene was small.
