In this paper, the authors consider an approximation to the isentropic planar Magneto-hydrodynamics(MHD for short) equations by a kind of relaxed Euler-type system. The approximation is based on the generalization of the Maxwell law for nonNewtonian fluids together with the Maxwell correction for the Ampe`re law, hence the approximate system becomes a first-order quasilinear symmetrizable hyperbolic systems with partial dissipation. They establish the global-in-time smooth solutions to the approximate Euler-type equations in a small neighbourhood of constant equilibrium states and obtain the global-in-time convergence towards the isentropic planar MHD equations. In addition, they also establish the global-in-time error estimates of the limit based on stream function techniques and energy estimates for error variables.

原子级厚度的二维层状晶体材料具有丰富的物理特性,在新型微纳米器件领域展现出重要的发展潜力,相关的器件制备和性能研究也引起了广泛的关注.二维材料微纳米器件的制备需要经过二维材料的转移及金属电极的淀积等一系列过程.然而,在传统的制备流程中所涉及多步工艺需要用到诸多不同设备,如二维材料转移对准系统、电子束曝光系统,或是光刻系统,而且往往在一些步骤中涉及有机溶液处理,有可能会对样品带来一些不利的影响.本文设计展示了一种能够实现二维材料微纳米器件制备的多功能系统,该系统不仅可以实现二维材料的高效转移,而且可以直接进行金属电极的准确淀积,并且整个加工流程不涉及溶液处理,具有操作方便、效率高、样品污染少等优点.基于该多功能系统,我们成功制备出了MoS;场效应晶体管并对器件进行了光学表征和电学性能测试,展现了这一系统在高效制备微纳器件方面的潜力.

Due to extreme difficulties in numerical simulations of Euler-Maxwell equations, which are caused by the highly complicated structures of the equations, this paper concerns the simplification of the Euler-Maxwell system through the zero-relaxation limit towards drift-diffusion equations with non-constant doping *** carry out the global-in-time convergence analysis by establishing uniform estimates of solutions near nonconstant equilibrium regarding the relaxation parameter and passing to the limit by using classical compactness arguments. Furthermore, we generalize the stream function method to the non-constant equilibrium case, and together with the anti-symmetric structure of the error system and an induction argument, we establish globalin-time error estimates between smooth solutions to the Euler-Maxwell system and those to the drift-diffusion system, which are bounded by some power of the relaxation parameter.
