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.

In high-impedance current-input inverting configurations, where a length of shielded wire is used to guard the lead from the current source to the amplifier's inverting input, the guard should either be driven by a buffer at the same potential as the non-inverting input, or be tied directly to the non-inverting input, with a second outer shield connected to the signal's reference point.

如果将运放接成反相放大器的形式，并且在信号源与运放反相端之间用一段带有屏蔽层的导线来充当的防护罩，那么对防护罩的处理有两种选择：要么用一个缓冲跟随器来驱动，跟随器输出端与运放同相端电位相等，而且除跟随器外，防护罩不与其他点接触；要么将防护罩直接接到运放的同相端，然后在其外面加一个屏蔽层，并且将屏蔽层连接到信号的参考电位。

Self-buckled kerbstones consist of two different layers of compound cement. They are of many kinds of designs and colors. On the outer layer, there are illuminating materials made by special materials. The inner layers are made of common cement, so they are low in price. At the two ends of the kerbstone, there are concave and raised troughs for self-buckling. So they are convenient in installment. Different size of holes for draining water can be drilled according to actual situation.

自扣式侧石是由两层不同颗粒级配比的复合混凝土构成，具有多种图案和色彩，面层附有由特殊材料制作成的发光材料，内层为普通混凝土，成本低廉；侧石的两端有凹凸卡槽自扣连接，安装方便，不易沉降和倾斜；还可根据不同需要的距离可在不同位置上留有大小不同的排水孔，雨天能够及时排除路面积水，从而丰富花池，花坛及道路两侧绿化带水源。
