这个关系的重要性在于提供高的屈服和拉伸强度。
The significance of this relationship is providing for high yield and tensile strengths.
研究进一步表明,材料变形的难易程度又与变温循环过程,热疲劳试样拉伸应力的增加和材料屈服强度的降低有关。
Moreover, it is revealed that the deformation resistance in the thermal cycle process is related to the increase of its tensile stress and the decrease of yield strength.
结果表明:PVC的拉伸屈服强度随外力作用速度的提高而提高,断裂伸长率却随之下降。
The results showed that with the the increase of outside force velocity, the tension yield strength of PVC increased, but its breaking elongation decreased.
