Bascd on test results, the effect of environment temperature, exciting frequency, strain magnitude and hysteretic time on the mechanical properties of ZN-1 and ZN-2 visoelastic materials has been quantitatively discussed. The temperature improving pro- cesses of ZN-1 and ZN-2 during a short and long period of exciting are propcised. The model parameters of the four-parameter model have been determdned for ZN-1 and ZN-2 respectively.
