1·With the increase of the modifier dosage, creep compliance declined and recovery rate raised in the same time, the modification effect is better.

随着改性剂掺量的增大，蠕变柔量降低，恢复率增大，改性效果越好。

2·Based on the experimental study, volume creep compliance, volume relaxation modulus and their main curves and initial void content of solid propellant are given.

通过实验研究，给出了固体推进剂的体积蠕变柔量、体积松弛模量和材料的初始气孔率。

3·In this paper, the creep compliance of Hot-plate welded joint of PE80 pipe is measured, and the effect of creep on the crack tip stress field in the weld is investigated.

本文测定了燃气用PE80管材热板焊接接头的蠕变柔量，研究了蠕变对焊缝裂尖应力场的影响。
