摘　　要：在动三轴仪上使用自制的高灵敏度应变计量测到应变ε_d=10^(-6)～10^(-2)的模量阻尼,提出了最大动模量的确定方法。Using a strainometer with high sensitivity, modulus and damping, from the axial strain 10^(-6) to 10^(-2), were measured. The important parameter under cyclic loading, the maximum modulus Edmax or Gdmax , was determined using a new method. The other methods and concepts on the test and analysis of cyclic loading were discussed.
