碳酸钙溶解的界面因素及水运动条件

Influence of Interface Character and Water Movement on Solution of CaCO_3

本文从碳酸钙的溶解实验着手，讨论了不同的水—气界面面积及水—固界面面积对ＣａＣＯ３溶解速率的影响，以及水的运动条件对ＣａＣＯ３溶解速度的影响。作者利用单位增长率的概念，对比了不同界面对ＣａＣＯ３溶解的影响程度，得出了水—气界面的反应在整个体系中是最慢的。根据水运动条件对碳酸钙沉积过程及溶解过程的影响，本文还讨论了水运动条件在ＣａＣＯ３溶解及沉积矛盾运动中的意义．

According to the test of CaCO3 solution, this paper deals with the influeces of different water-air and water-solid interfaces and the conditions of water movement on the solution velocity of CaCO3, Using the unit increase rate, the authors have compared the degrees of different interfaces' influences on the solution of CaCO3 and pointed out that the reaction on the water-air interfaces is the slowest in whole process. In light of the influence of the water movement conditions on the processes of the solution and deposition of CaCO3, the authors also expound the significance of the water movement conditions in solution and deposition of CaCO3.
