摘　　要：利用约利弹簧秤对橡皮筋的力的滞后特性进行了实验分析,并由此说明了不能用橡皮筋做测力计的物理机理,为检验弹簧的质量提供了一种实验途径及理论依据.Using Jolly spring balance, the hysteresis property of tension exerted by elastic band is analyzed, as well as the physical mechanism that points out that an elastic band can＇t be used to measure force. The experimental way and theoretical principle are provided to check the quality of springs.

关 键 词：滞后特性 劲度系数 约利弹簧秤
