报道了利用激光超声技术测量纳米材料杨氏模量的测试方法。根据测量声波在材料内传播的时间和试样的厚度，确定声波在材料内的传播速度，进而由材料的密度即可计算出材料的杨氏模量；并对不同烧结温度下纳米氧化锆进行了测量，结果表明纳米氧化锆的杨氏模量随烧结温度的升高而增加，此方法简便实用，并对试样的形状无特殊要求。
The test method for measuring the Young’s modulus of nanomaterials by using laser ultrasonic technique was reported. According to measuring the propagation time of acoustic wave in the material and the thickness of the sample, the propagation velocity of the acoustic wave in the material is determined, and then the Young’s modulus of the material can be calculated from the density of the material; and the nanosized zirconia under different sintering temperatures The results show that the Young’s modulus of nano-zirconia increases with the increase of sintering temperature. This method is simple and practical, and the shape of the sample has no special requirements.
