分析了相对论磁化等离子体动力学方程在电磁应力能量占压强和静止质量能量密度占优势的极限情况下的动力学方程。这些方程的天真表述被证明不是双曲线的。用对所有物理解都为零的项修改方程，我们得到了一个对称双曲发展系统，它应该表现出更好的数值行为。
We analyze the equations of relativistic magnetized plasma dynamics in the limiting case that electromagnetic stress-energy is dominant over pressure and rest mass energy density. The naive formulation of these equations is shown to be not hyperbolic. Modifying the equations by terms that vanish for all physical solutions, we obtain a symmetric hyperbolic evolution system, which should exhibit improved numerical behavior.
