求翻译：韧性反映夹层材料吸收冲击能量的能力，它可近似地以材料的抗拉强度与延伸率之积量度，一般以ＣＢＲ试验顶破强度来表示其表面硬度；是什么意思？

Toughness of laminated material to reflect the ability to absorb impact energy, it can be approximated to the material tensile strength and elongation of the product measure, generally bursting test strength of CBR to represent the surface hardness;

resilience reflects laminated material of absorbing the shock energy capacity in the form of material, it may be similar to the tensile strength and elongation of the MPFA measurements, General to CBR pilot relations to express its surface hardness in intensity;

Tough reflection band material absorption impact energy ability, it may approximately by the material tensile strength and the elongation ratio product of measurement, generally goes against the broken intensity by the CBR experiment to express its skin hardness;

Toughness reflect sandwich material's ability to absorb impact energy, which can be approximately to measure tensile strength and elongation of the plot of the material, generally expressed as CBR test and bursting strength of its surface hardness;

The toughness reflects the intermediate layer material absorbs the ability to assault energy, it can be by the accumulate and measuring of the tensile strength of the material and coefficient of elongation approximately, generally show its superficial hardness by the means that CBR tests very broken
