Based on the Biot s two-phase theory for fluid-saturated porous media, considering the inertia force of the solid and the liquid, and the coupling function between the solid and the liquid, and the compressibility of the liquid in allusion to the character of the nearly saturated soils. The dynamic governing differential equations are solved by Hankel transform. Then, considering the boundary condition, the dual integral equations of vertical vibration are established which are reduced to Fredholm integral equation of the second kind.

本文基于Biot两相介质动力固结理论，针对准饱和土地基的特点，考虑了流体的可压缩性，土体和流体的惯性及水土之间的耦合作用，运用Hankel变换技术求解动力控制方程，然后按混合边值条件建立起对偶积分方程，并将其化为易于数值计算的第二类Fredholm积分方程，分别研究了准饱和土半空间地基、上覆单相弹性层的准饱和土地基和准饱和粘弹性地基上刚性基础的竖向振动特性。

The moisture flux in case 2006 was more than case 2005. The frontogenesis process in case 2006 was obvious; it showed that the front system was accompanied with a strong temperature gradient. The mid and low-level frontogenesis process played an important role in the development and maintenance of causing the front convective systems. The jets were formed with the difference of horizontal ageostrophic wind in vertical direction.

由水气收支计算可得到水平水气通量辐合对於对流系统之水气来源扮演正回馈作用，其中2006年个案中水气通量较2005年个案来得大。2006年个案之锋生过程显著，中低层锋生过程扮演导致锋面对流系统之发展与维持重要角色；而低层喷流生成的条件主要来自於横向非地转风垂直分布之喷生作用。
