The constant creep rate was increased and creep-resistance breaking time and creep breaking elongation were decreased with the increase of applied stress.
随施加应力的增大，纤维的恒蠕变速率增大，抗蠕变断裂时间变小，蠕变断裂伸长变小。
2
Used for testing indexes of single fiber, such as breaking tenacity, elongation at break, load at specified elongation, elongation at specified load, creep, etc.
用于测定各种单纤维的断裂强力、裂伸长率、伸长负荷、负荷伸长、变等性能指标。

Combine with the creep experimental results, the three methods for measure plastic percentage elongation of creep are studied and analysed.
