+$ \frac{\partial n_{e}}{\partial t} + \nabla\cdot(n_{e} \bold{u}) = I-r $[[BR]]
+
+I is the rate of ionizations per unit volume and r is the rate of recombinations per unit volume[[BR]]
+
+$ I = -\nabla\cdot J$[[BR]]
+
+J is the flux of ionizing photons. Inside the front where the gas is nearly completely ionized the recombination rate[[BR]]
+$ r=\alpha n_{e}^{2} $[[BR]]
