This paper deals with two problems, nonzero -offset Fresnel zone in homogeneous media, and the effect of velocity error resulted in NMO correction and stacking on vertical resolution.
本文讨论了均匀介质情况下非零炮检距菲涅耳带和动校、叠加中速度误差对纵向分辨率的影响这两个问题。

With increasing of superficial gas velocities, the liquid flow regime was changed from homogeneous to transitional and radial gradient of axial liquid velocity was rather small.
且当表观气速增大，初始流体流动处于由均匀流型向过渡流型的转变，轴向液体速度在径向的梯度非常小；

The flame velocity of flammable gas deflagration in a large closed vessel has an accelerating process, and the pressure distribution is not homogeneous.
