消融等离子体对金属丝阵Z箍缩内爆动力学的影响

结合火箭模型和雪耙模型，建立了完整自洽的丝阵Z箍缩消融-内爆模型，分析了消融等离子体对丝阵Z箍缩内爆动力学的影响，得到了比零维薄壳模型合理的内爆轨迹。在考虑消融等离子体向轴运动的情况下，计算了丝阵Z箍缩的内爆时间、内爆速度和动能，并且与零维薄壳模型进行了对比。结果表明，考虑消融等离子体运动得到的内爆动能低于零维薄壳模型计算结果，其内爆动能最大值所对应的负载线质量也低于薄壳模型。

Effect of ablated-plasma on the implosion dynamics of wire array Z pinches

A self-consistent ablation-implosion model was established in which Rocket model and snowplow model were well combined. The effects of ablated plasma on the implosion dynamics of wire array Z pinches were studied and a rational implosion trajectory was obtained. The implosion time, velocity and kinetic energy were calculated and the results were compared with that of the zero-dimension thin shell model. It was found that the implosion kinetic energy and the mass of wire array (per unit length) for the maximal kinetic energy calculated from our model was less and smaller than the zero-dimension model respectively.
