摘　　要：牧草从首次压缩到离开压缩室的整个压缩过程中，牧草在整个压缩室不同位置的受力、变形和变形恢复等均是变化的。该文利用电测技术对其进行测试研究，获得了相应的变化规律，这对高密度捆草机压缩室长度的确定和捆束装置的选择等均有重要意义。The compressing force, compressing deformation and recovering of hay compressed at the different position of compressing chamber varied from first compressing to hay compressed departing from the chamber. In the paper the above parameters were measured using electric measurement technology, and the regular patterns of appropriate parameters were obtained. It is important for designing the length of chamber and determining the optimum position of mounting knotter.
