中文摘要：

空气故障被高力量的微波容易引起，它能有二互相直角并且 heterophase 电场部件。为这个盒子，电子动量保存方程被采用为加热电子推出电场力量和有效电场。然后，电场力量的公式被介绍进全球模型模仿空气故障。从全球模型的故障预言与试验性的数据同意很好。模拟结果证明电子温度对二个电子地部件之间的阶段差别敏感，当后者能显然在低电子温度振幅影响电子密度的生长时。氮和氧的电离由于分离附件导致电子密度，和密度损失的生长，分离再结合在低电子温度仅仅是明显的。

英文摘要：

The air breakdown is easily caused by the high-power microwave, which can have two mutually orthogonal and heterophase electric field components. For this case, the electron momentum conservation equation is employed to deduce the electric field power and effective electric field for heating electrons. Then the formula of the electric field power is introduced into the global model to simulate the air breakdown. The breakdown prediction from the global model agrees well with the experimental data. Simulation results show that the electron temperature is sensitive to the phase difference between the two electron field components, while the latter can affect obviously the growth of the electron density at low electron temperature amplitudes. The ionization of nitrogen and oxygen induces the growth of electron density, and the density loss due to the dissociative attachment and dissociative recombination is obvious only at low electron temperatures.
