We present the numerical calculation of the model of aluminum flyer-vacuum-target with high power laser driving.The results show that the parameters of laser and target's structure have great effects on the state of flyer and the character of shock-waves in the target.If we select the parameters of laser and target's structure reasonably, we can achieve approximately symmetric impact between flyer and target;moreover,the shock-wave in the target has a stable area with a certain spatial width.So,if we choose the three-step-target with a suitable thickness,we can approach an absolute measurement of equation-of-state.
