By using one-dimension FDTD method we simulates the decay of double exponential pulse through the soil media, and its refractive time-domain wave shape is discussed in detail.
We accordingly propose to take the marginal decay curve (whose function is simple) as a criterion to check if an observed pulse could be taken as a candidate suffered from the Doppler effect.
于是我们提出把极限衰减曲线作为检验观测脉冲是否是多普勒效应作用下的结果的一个标准。

Add the workpiece fixed in the coil, coil discharge at the moment have a damping pulse magnetic field decay, so that the loss of magnetic parts.
