【摘要】 地下水污染系统，一般由非饱和带与饱和带两子系统组成，潜水面为两者的界面。已有的模拟试验多对其进行分段研究，认为污染物在系统中的运移规律为两者中的叠加。由于系统中存在界面过程和子系统间的相互作用，整个系统即饱和─非饱和带联合试验研究的结果较分段模拟结果更客观地反映污染物在系统中的运移规律；且这种联合研究在数学处理上也具有一定的优势。因此，饱和─非饱和流溶质运移的联合研究更值得重视。更多还原

【Abstract】 The groundwater contamination system is usually made up of two sub- systems of unsaturated zone and saturated zone. The phreatic water surface is their interface. Most of the formally studied simulation test being con ducted by seperated zone, and the migration law of the contaminants in the system is considered as the superposition of the two zones. Owing to the existence of interface process and the interaction between the sub - systems, the re sult of the combined experimental study of the whole system, i. e. the saturated- unsaturated zones, as compared with the result of the asetional simulation test, can more objectively reflect the migration law of the contaminant in the system. Moreover, this combined study opssesses a certain superiority on the mathematic processing. Chnse quently, the combined study of the migration of the solute in saturated- unsaturated flow deserves more attention.更多还原
