随着电子技术的不断发展，计算机技术与仪器技术结合得越来越紧密，出现了大量的任意波形发生器，它们能产生的波形不断丰富，除上面提到的基本波形外，还能产生Chirp信号、Sinc信号、MultiTone信号、脉冲信号以及各种噪声信号等。

Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.
