得到谱指数和不规则体的漂移速度后，可以进一步得到由外尺度、电子密度均方起伏和不规则体厚度三个参数组成的表达式的值。

Then the expression, consisting of the outer scale, the thickness of the irregular slab and the RMS electron density fluctuation, can be got further.

给出了等离子体电子密度线性分布和指数分布时，雷达电磁波的频率、电子碰撞频率、等离子体密度对电磁波衰减的影响。

For different plasma-density profiles, the effects of the frequency of EM wave, collisional frequency and plasma density on the attenuation of electromagnetic wave were discussed.
