在前一讲中着重介绍了地下水的形成及赋存条件,从而可知,地下水与地表水不同,它埋藏和运动于岩石的空隙之中,赋存与环境有密切的关系,这种关系造成了地下水更为复杂多样的化学成分以及表现出不同的物理性质。了解熟悉这些性质和成份,对于合理的开发利用地下水是十分必要的。在本讲中,我们将予以简要的介绍。一、地下水的物理性质 In the previous lecture, the formation and occurrence conditions of groundwater were introduced emphatically. Therefore, groundwater is different from surface water and it is buried and moved in the gap of the rock. The relationship between occurrence and environment is closely related to it Groundwater is more complex and diverse in chemical composition and exhibits different physical properties. Understanding of these properties and ingredients is essential for the proper exploitation of groundwater. In this talk, we will give a brief introduction. First, the physical properties of groundwater
