Oxyhydrogen isotope relationship curve in the region indicates that the samples basically distribute in the upper left of local rainwater line and an obvious phenomenon of reverse "Oxygen drifting" exists. This kind of isotope distribution is the only one in the most karst groundwater in northern karat spring area that the authors have ever studied.

By using the calculated results of EET theory, the local valence electron structure elements of residual chemical bonds of Al-Si and Mg-Al alloy melts, that is, the residual bond structure models, were established. From the viewpoint of effect of pressure on melt structure, the essential reason of deviation phenomenon for maximum solution point and eutectic point in thermodynamics equilibrium phase diagram was analysed. Moreover, under pressure condition, the change of thermodynamics equilibrium phase diagram was macroscopic reflection of microstructure change of alloy melt.
