tensile-strength造句

• The results show that the tensile - strength and the resistance to water , to ultraviolet and to heat of compound modified waterproofing films exceed their of single modified waterproofing films
  结果表明：复合改性涂膜拉伸强度增大，并且耐水性、耐紫外老化性和耐热老化性优于同样条件下单一改性防水涂膜。
• The studies expressed that the tensile - strength declined with the growth of dose rate after the radiation treatment , and at the same time , the gel content had extreme value with the change of the dose rate . the surface of uhmwpe fibers showed some irregular micro - pits and dents after radiation treatment , narnely rough degree increasing . their number and deepness increased with increase of dose . and this phenomenon is the most obvious when the dose rate was 8 . 5kgy / s and the dose was 400kgy . at the same time some containing oxygen groups , including hydroxyl group , carbonyl group and carboxyl group , were introduced into the fiber surface which was exposed to the air
  研究表明， uhmwpe纤维经电子束辐照处理后，纤维的拉伸断裂强度随剂量率的增加呈下降趋势，凝胶含量随着剂量率的变化存在极值。纤维表面出现了不规则的微裂纹和凹痕，随着剂量的增大，电子束对纤维表面的刻蚀程度增加，在本研究中以剂量为400kgy剂量率为8 . 5kgy s时刻蚀效应最为明显。同时，在空气中进行辐照时，纤维表面被引入了一些含氧基团，包括羟基、羰基和羧基。
• Moreover , rare earth ceo2 can clean the melt and the face of reinforced particles and improve the wettability between the reinforced phase and melt and the property of material . proper additive mg and rare earth can improve the hardness , wear - resisting property tensile - strength , elongation percentage of tic / al , tic / al - si composite
