1·Light calcium carbonate was usually manufactured by chemical process, so its high alkalinity could not be avoided easily.
由于轻质碳酸钙都是化学法生产，碱度高不易避免，而且轻质碳酸钙的生产原料质量直接影响其碱度。
2·For example: HP vesicant, lees, light calcium carbonate, active white earth, magnetic powder, graphite, medical slag and so on.
如：H P发泡剂、酒糟渣、轻质碳酸钙、活性白土、磁粉、石墨、药渣。
3·The results show that this method is suited to character activated light calcium carbonate and activated heavy calcium carbonate which particle is very fine.
结果表明，该方法适于表征活性轻质碳酸钙和颗粒极细的活性重质碳酸钙。
4·The effects of the contents of activated light calcium carbonate, PE wax and acrylic ester(ACR) on the surface gloss of plastics profile shapes were studied.
研究了活性轻质碳酸钙（活性钙）、聚乙烯蜡（PE蜡）、丙烯酸酯（ACR）用量对型材表面光亮度的影响。结果表明活性钙用量越多，型材表面光亮度越差；
5·Based on the theory of sonochemistry, the influence of ultrasound on the carbonation process of the synthesis of nanometer light calcium carbonate is studied initiatively.
根据声化学的有关原理初步探索了超声场对于纳米级轻质碳酸钙合成碳化过程的影响。
6·By using property of separating out water at high temperature for polyvinyl alcohol formaldehyde solution, kaolin and light calcium carbonate can be directly added, and technique is simplified.
在制备方法上利用聚乙烯醇缩甲醛溶液高温析水的性质，直接加入高岭土、轻质碳酸钙制胶，简化了工艺。
7·Dry powder granule raw materials which have special requirements to drying. for example: HP vesica nt lees light calcium carbonate active white earth magnetic powder graphite medical slag and so on.
对有特殊要求的粉状，颗粒状物料的干燥。如：h p发泡剂、酒糟渣、轻质碳酸钙、活性白土、磁粉、石墨、药渣。
8·"There were some proponents of a bigger dairy industry in Laos to improve a calcium deficiency," says Durst, whose favourite is Fried wasp - "very crispy and a nice light snack".
杜斯特最喜欢的是炸黄蜂、非常脆非常可口清淡的小吃。他说：“老挝一个较大的乳制品加工厂中有很多人支持改善钙缺乏。”
9·Under UV light, clean sand appears purple or black. Some minerals, such as calcium carbonate in seashells, glow blue, as does a shovel handle in the picture above.
紫外线照射下，干净的沙子呈紫色或黑色。有些矿物，如海贝中的碳酸钙，会闪着蓝光，就如同上图中的铁锹的把手。
10·They would leave subtle clues in the isotopic composition of the limestone by shifting the ratios of light to heavy carbon and oxygen atoms in its calcium carbonate.
因为如果是那样的话，阳光将会被转换成大量的碳、氧原子保存到石灰岩中的碳酸钙里，而事实却是，岩层的同位素组成（Isotopic composition）中没有留下任何蛛丝马迹。
