calcium carbonate light的意思|示意

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；

Both of the coarse and fine light-weight aggregates in the concrete were natural calcium carbonate nucleations with loose and porous structure.

“混凝土”中的轻质粗、细集料是一种组织疏松、多孔的天然碳酸钙结核。

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。

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。

The fluorine reducing agent is prepared from magnesium carbonate, light magnesium carbonate, hydroxyl calcium carbonic phosphate and animal bone through a definite technological process.

本发明是一种可以降低饮水氟含量的降氟剂，是由亲氟的化合物制成，主要原料有碳酸镁、轻质碳酸镁、羟基碳酸磷酸钙、动物骨等。

Coccolithophores are microorganisms that are covered in plate-like shells made out of calcium carbonate (chalk). The chalky shells reflect light, turning the ocean a milky turquoise color.

石灰质鞭毛虫(coccolithophores)是一类覆盖在碳酸钙(粉笔的主要成分)岩石板状外壳上的微生物。
