Used for testing indexes of polyurethane monofilament, such as breaking tenacity, elongation at break, load at specified elongation, relaxation of stress, plastic deformation, etc.
用于测定氨纶丝断裂强度、断裂伸长率、定伸长负荷、应力松弛，塑性变形等性能指标。

The results of computation indicate that the elongation of IF steel, the temperature of zero plastic deformation of low-temperature steel predicted are in agreement with the experimental data.
计算结果表明，IF钢的延伸率、耐低温钢的无塑性变形温度预报值与实测值相当符合。

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