摘　　要：研究了中空纤维膜拉伸过程中弹性阶段的测试方法,通过设定样品不同的拉伸范围,测量其拉伸后的恢复情况,处理规定非比例延伸强度对应的力值和伸长量,最终确定膜拉伸过程中的弹性阶段及在该阶段样品性能是否发生变化.The study on the test method for elastic stage during tensile process of hollow fiber membrane was carried out.By setting different stretching ranges of samples,the membrane recoveries after tension were measured.By testing the force and elongation of the specified non-proportional extension strength,the elastic stage and whether the saples properties are changed have been determied.

关 键 词：弹性形变 塑性形变 规定非比例延伸强度
