On the paas - normalized plots, the parent granite and the granite weathering crust are enriched in lree without ce anomaly. while the groundwaters are also enriched in lree, they display significant negative ce anomaly, indicating the fractionation of ce during water - rock interaction. based on the study of two profiles of granitoid weathering crust, we concluded that ree concentrations in the groundwaters from the granitoid weathering crust are likely related to the continued chemical weathering, as well as the ree concentrations in the crust near the water table, clay concentration and the wate r ph values
地下水與母巖、風化殼稀土的paas標準化分佈模式基本相似，呈lree富集型，母巖中無ce異常，而水樣中有ce負異常，表明ce在水巖作用過程中發生明顯的分異；通過研究兩個典型花崗巖風化殼剖面發現，地下水的稀土含量與連續的化學風化，以及水位附近剖面上的稀土含量、粘土礦物含量以及水的ph值等有關。 -
An integration of neural network and genetic algorithm method is proposed for optimizing the operating conditions in order to lower energy consumption of gas fractionation plant. this paper synthesizes the current chemical engineering process optimization and characterizes chemical engineering process many layer optimizations frame to proceeds first, and treatise detailed operation optimization at the same time
