| 摘 要： | 研究了低频超声作用下碳酸钙的结晶和沉淀过程．与单独搅拌相比，在超声作用下碳酸钙沉淀颗粒较小，不易粘附于容器器壁上，溶液浊度下降缓慢．扫描电镜分析表明，在超声作用下碳酸钙沉淀呈片状，而在搅拌条件下呈方解石结构．

| Abstract: | The precipitation process of calcium carbonate exposed to low-frequency ultrasound was investigated.In comparison with stirring,the size of the precipitate was smaller and the turbidity of the solution decreased slower.The SEM analysis revealed that the crystal was mainly composed of pellets after sonication compared to that of calcite after stirring. |
