利用泊松方程得到PN结热平衡下的电势分布(Poisson equation PN junction thermal equilibrium electrical potential distribution)

合成地震记录是用声波测井或垂直地震剖面资料经过人工合成转换成的地震记录（地震道） 合成记录的制作是一个简化的一维正演的过程，合成记录F(t)是地震子波S(t)与反射系数R(t)褶积的结果。(Synthetic seismogram is sonic or vertical seismic profile data after conversion into synthetic seismograms (seismic trace) the production of synthetic seismogram is a simplified one-dimensional forward modeling process, synthetic seismogram F (t) is the seismic wavelet S (t) and the reflection coefficient R (t) the convolution results.)
