The results showed that, as the temperature rose, the moisture absorption isotherms of the product varied gradually from remarkable inverse-S shape to the curve which was similar to that of exponent function. 绘制研究结果表明,随着温度的升高该产品的等温吸湿曲线从显著的呈反S型,逐渐趋近于类似指数函数曲线。
The energy absorption efficiencies are dependent on the ratio of upper yield strength to lower yield strength, the ratio of the yield strain to the densification strain, and the ratio of the elastic module to the strain hard exponent. 而其能量吸收效率则受上下屈服强度之比、屈服应变与密实化应变之比、弹性模量和应变硬化指数之比影响。
The results are as follows: the energy absorption capacities of Al2O3k/ Al porous composites mainly lie on the yield strength, the length of the collapse plateau region and the strain hard exponent. 研究结果表明:Al2O3k/Al多孔材料的能量吸收能力与屈服强度、平台段应变和应变硬化指数有关。
