1
考虑高温下钢材的弹性模量以及屈服强度的变化。
Variation of the elastic modulus and yield strength of steel with temperature rise was considered.
2
若实验过程中假设钢管的弹性模量和钢材的弹性模量相等且为常数，则保温层摩擦力和无保温管与有保温管伸长量之差成正比；
The experiment is assumed that the elastic modulus of the steel pipe equal and constant, the insulation layer friction proportional to the difference of elongation.
