Based on the first linearized Boussinesq equation, analytical solution of the transient groundwater model, which is used for describing phreatic flow in a semi-infinite aquifer bounded by a linear stream and subjected to time-dependent vertical seepage, is derived out by Laplace transform and the convolution integral.

在河渠边界控制下的半无限含水层中，对时变垂向入渗影响下的潜水非稳定渗流模型，利用Boussinesq第一线性化方法，通过Laplace变换并结合卷积原理，导出模型的解析解。

Third,a semi-numerical method that uses finite difference for time toreplace Laplace transform for time is presented.

The layout of SGA92150 semi-trailer 's frame,the longitudinal and latitudinal beams and the joint of them are designed in this paper.

对SGA92150型半挂车车架的总体布置、纵梁、横梁、纵梁与横梁的连接等进行了设计。

In combination with the crushed rock slope as an example, the allocation of an anchorage force on longitudinal beams and transverse beams is calculated by adopting the distribution coefficient law of the nodal form at first. Then the internal forces of the lattice beam are calculated respectively through the software on the basis of Winkler elastic foundation model and the semi-infinite foundation model, and then compared with the internal forces which are based on simplified foundation pressure calculation. The active pressure of rock is calculated approximately by Ranking soil pressure theory in the working stage. Sequentially, the reinforcing bars are disposed by two-stage's averagely calculated values.

以破碎岩质边坡为例，采用节点荷载分配法计算了锚索锚固力在格构梁纵、横梁之间的分配比率，然后基于Winkler弹性地基模型和弹性半空间地基模型分别计算格构梁在张拉阶段的内力，并与采用简化的地基反力计算值对比；采用朗肯土压力理论近似计算在工作阶段主动岩体压力，将地梁视为在线性分布力作用下倒置于坡面上的连续梁，按力矩分配法计算地梁内力，取两阶段计算平均值进行配筋。

他表示，初步统计，温州80％的民营企业还在正常发展，但20％左右的企业遭遇较大冲击，处于停工半停工状态。
