The changes of moisture absorption properties, tensile strength, fractureelongation and elastic modulus of APMOC fiber with aging time were investigated through the hygrothermal aging test.
通过湿热老化试验，研究了APMOC纤维吸湿性能、拉伸强度、断裂延长率以及弹性模量随老化时间的变化。
2
The tensile strength and elongation after fracture vary little after rolling.
在下屈服强度降低的同时，其抗拉强度和断后伸长率变化不大。
3
Unilateral axial dynamic fixators were also successfully used in the treatment of comminuted fracture, in replantation of severed limbs and elongation of bones.
