磁扩散 meaning in English

magnetic diffusion

Before reforming the code to be a mhd , the boundary condition of sss code is modified , so that we can calculate the electro - magnetic implosion of ideal conductive liner , where the magnetic field diffusion is neglected
在进行一维磁流体力学改造之前，我们计算了磁压驱动没有磁扩散的理想导体内爆算例，主要是对sss程序的压力脉冲边界条件进行修改。
The procedure to modify the sss code is as follow : at first the hom eos ( equation of state ) is replaced by the sesame eos , secondly the magnetic force is added to the momentum equation , the ohmic heating rate is added to the energy conservation equation
对sss程序改造过程大致如下：首先以sesame数据库物态方程替换sss程序原有的物态方程；其次在动量守恒方程中加上洛仑兹力项，在能量守恒方程中加上单位质量焦耳加热项，通过麦克斯韦方程推导出磁扩散方程。
