本文提出的导线动力学模型（WDM）可以有效地代替一般的零维模型，用于模拟任意形状导线阵列的内爆，包括高线数嵌套载荷和平面阵列载荷。快速、廉价的WDM模型可以预测阵列内爆时间和动能的热化速率，并可以估计x射线脉冲的时间。该波分复用器除了能够实现复杂结构线阵载荷的设计和优化外，还能再现由于感应电流传递而引起的线阵内爆动力学的具体特征，这使波分复用器成为一种有价值的磁流体动力学模型的放大。
This paper presents the wire dynamics model (WDM), which can effectively replace the generic 0D (zero-dimensional) model in simulation of the implosions of arbitrary shaped wire arrays, including high-wire-number nested and planar array loads at multi-MA generators. Fast and inexpensive WDM modeling can predict the array implosion time and the rate of thermalization of the kinetic energy, and can estimate the timing of the x-ray pulse. Besides serving the purposes of the design and optimization of the wire array loads of complex configurations, the WDM reproduces the specific features of the wire array implosion dynamics due to the inductive current transfer, which makes the WDM a valuable amplification of the magnetohydrodynamic models.
