碳酸钙沉积晶体形态特征及环境条件研究

THE REASEARCH ON THE FEATURE OF CRYSTAL FORM AND ENVIRONMENTAL CONDITION IN CaCO 3 DEPOSITION PROCESS

作者通过一系列实验，认为在洞穴ＣａＣＯ３沉积过程中，由ＣＯ２逸出快慢决定了ＣａＣＯ３的沉积速度，加之环境条件的影响，从而导致了ＣａＣＯ３沉积晶体不同的形态特征，其结晶程度也有巨大的差异。具体地讲，由于水动力条件、水－气界面面积、温度、环境ＣＯ２分压等因素变化都会引起洞穴ＣａＣＯ３沉积晶体的形态变化，其中结晶位置的环境条件也控制着晶体的发育状况及其形态特征。

From a serial test on CaCO 3 deposit,the article present in the process of CaCO 3 deposit.The velocity of CaCO 3 deposit depend on velocity of CO 2 escaping,in different environmental condition the CaCO 3 crystal will show different feature.Including the different scale of the crystal Mainly,factors such as water moving,area of water-air interface,temperature,P CO 2 etc.will lead to different velocity of depositing,and result in different crystal feature different shape and crystal extent feature.
