实验结果表明，超强吸水树脂与原土混合作为回填材料能够增大地下换热器的换热量，提高地源热泵系统的效率和稳定性，适合于在干旱、岩土体非饱和及地下水位较低的地区应用。

In view of inhomogeneous distribution of fluid pressure, fault-valve behavior and the coupled equations of the current density and fluid flow within the Earth's crust, especially, the observed anomalies in electrical field showed a similar pattern of rapid starting and slow decay, some of these anomalies associated with episodical spouting from borehole or the increase of fluid pressure in wells, it is reasonable to consider that the source of precursory electrical field anomalies is the streaming potential mechanism.

鉴於地下流体压力分佈不均匀、断层阀作用及地下电流密度与流体流的耦合方程，特别是由於电场异常显示出快急始慢衰减的特殊图型，电场异常有的与废油井间歇自喷有关，有的与流体压力增高有关，故认为过滤电势作为电场前兆机制是合理的。

研究城市地下工程开挖引起的地表移动和变形，对于减少开挖对地表和地下已有设施的不良影响，对于保护地表环境具有十分重要的意义。

It shows that the particle vibration velocity is related to the maximum single sound charge,distance from the blasting point uo the measured point,types of explosive and blocking condition.While transforming opencast mining into underground mining,if a goave is filled up with gangues,the surface rock mass of slope ca...

在露天转地下开采时，如果对采空区充填废石，不仅可以使边坡表面岩体处于有利的三向受力状态，回填废石体还起到了爆破减震作用，同时还有明显的高频滤波作用，有利于保持地下巷道的稳定性。

According to the character of condensate gas and the injected dry gas inside the UGS based on condensate gas reservoirs, the paper puts forward a mathematical model of multicycle working inventory for constant volume and weak waterbearing condensate gas reservoir by the mixed fluid density calculation method with molar volume balance and the gas equation of state.

为此，针对凝析气藏型地下储气库库内凝析气与注入干气混气的特点，从库存量的定义入手，利用摩尔体积权衡混合流体密度计算方法和气体状态方程，提出了定容和弱边底水凝析气藏型地下储气库多周期运行系列盘库计算的数学模型。

This paper uses a physical model to check the reliability of the numerical modeling proposed by Chen. As an example, this paper deals with a horizontal well pumpage underneath a river bed, or a vertical well adjacent to the bank of the river. We use the numerical method of Chen to simulate the groundwater flow pattern of the physical model.
