摘　　要：玉米果穗形状、籽粒类型、籽粒含水率、籽粒间缝隙走向、籽粒组砌规律、籽粒硬度等玉米果穗籽粒自身因素对其脱粒的难易程度以及损伤程度影响很大。其中,玉米果穗的缝隙变化趋势与缝隙线的走向规律对玉米果穗的脱粒效果及籽粒间循环力衰败的影响更大。为此,通过Micro Shot图像处理系统对玉米果穗籽粒间缝隙的走向进行微观分析,获得不同籽粒含水率的情况下,籽粒间缝隙走向及其变化规律对籽粒间循环力衰败规律的影响机理,进而为低损伤玉米脱粒机的研制提供理论参考。Self-factors of enrn ear kernel ,such us corn ear shape, kernel Iype, kernel humidity ratio, gap direction a- mong kernels, anangemen! law of eorn ear kernels, kernel hardness, etc＇. have a grcal influence on the difficult degree of threshing car and damage degree of kernel. Gap variation trend and gap direction among corn car kernels have a grea- ter influence on the threshing performanec and the eireulaling dinl decline, of corn car kernels. Therefore, gap direction among corn car kernels was analyzed through Micro shot image processing system in this article, and aeqt, ired the influenee mechanism of gap variation trend and gap direction among corn eat＂ kernels on the circulating dint decline among kernels under different humidity ratio. Then it will provide the reference of theoretical refercnc for the development of low -danmge Ihrcsher of eorn.
