用实验研究了普通橡皮筋中的滞后现象，结果表明橡皮筋的伸长量和外力的关系不完全满足胡克定律．在外力作用下橡皮筋也存在滞后回线，滞后回线与著名的磁滞回线有相似的几何形状
The hysteresis in normal rubber band was experimentally studied. The results show that the relationship between the elongation of rubber band and external force does not completely satisfy Hooke’s law. The rubber band also has a hysteresis loop under the external force. The hysteresis loop has a similar geometry with the famous hysteresis loop
