摘　　要：阐述了脉冲激振法测试耐火材料杨氏模量的原理和应用,指出脉冲激振法可用于耐火材料杨氏模量的单一温度点测试、升温过程连续测试,可同时用于杨氏模量、剪切模量和泊松比的测试;杨氏模量随温度变化的趋势,可为判断材料在高温下的力学性能变化提供依据。The principle and application of the pulse excitation method to test the Young’s modulus of refractories were expounded.It was pointed out that the pulse excitation method can be used to test the Young’s modulus at a specific temperature or the temperature rising process,it can also be used to test the Young’s modulus,the shear modulus and the Poisson’s ratio at the same time.The variation trend of the Young’s modulus vs the temperature can provide basis for judging the change of the mechanical properties of materials at high temperatures.
