Calcicole Describing plants that thrive on neutral to alkaline soils rich in calcium carbonate, i.e.

钙生植物：在富含碳酸钙的中性或碱性土壤中生存的植物。

Calcifuge Describing plants that grow on soils containing very little calcium carbonate, such as sandy or peaty soils and cannot grow on basic substrates such as most chalk and limestone soils.

嫌钙植物：在碳酸钙含量低的土壤中生存的植物，例如在沙地或泥地中生长。这种植物在石灰石之类的碱性基质中不能生长。

In this paper,experiments were conducted to study the preparation of the calcium lactate from shells with calcination only once.

In order to calcine calcium carbonate fines, the technique of high-temperature pelletization has successfully been used

为了煅烧碳酸钙细粉，已经成功地应用了高温成球技术。

In this paper,calcium sulfate whiskers were calcine d at different temperature and tested by XRD.

不同温度下煅烧硫酸钙晶须，并用XRD测定煅烧产物的结构，发现其晶型和晶格结构均有变化，600℃左右煅烧的硫酸钙晶须晶格结构最为致密。

When refractory gold ore is roasted by addition of lime, the calcine will contain some of calcium sulfide.

难处理金矿石加石灰法焙烧时，所得焙砂含有一定量的硫化钙。

There are other metal arsenates, such as those of Fe,Zn,Cu, and Pb, which are less soluble and more stable in the neutral pH region than calcium arsenates or ferric arsenate, but these have not been seriously considered as disposal forms.

还有其他金属砷酸盐，例如那些 Fe、 Zn、 Cu和 Pb，比起砷酸钙或者砷酸铁来，这些物质在中性的 pH 值范围内很少是可溶并且更稳定的，但是这些物质没被以处理的形式认真慎重地考虑过。

The most common methods of removing arsenic from aqueous process streams are by precipitation as arsenic sulfide, calcium arsenate, or ferric arsenate, but it has been suitable for direct disposal to uncontained sites as they will produce leachate containing arsenic.

从水中去除砷是最常用的做法，工艺流程是通过沉淀类似硫化砷、砷酸钙或者砷酸铁，由于会产生含砷的沥出夜，因此这种方法适合用于不限制排放场所的直接处置。

When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).

研究结果表明：在pH=10，吸附时间为30 min和骨炭加入量为0.6 g/L，饮用水砷初始质量浓度为0.5 mg/L时其砷去除率可达95.2%；骨炭吸附砷的行为同时符合Langmuir和Freundlich等温吸附模型；其吸附机理可能是Ca—OH官能团结合HASO4阴离子，并产生砷酸氢钙和羟基磷灰石的共沉淀，另外还存在离子交换作用；吸附柱的饱和吸附容量为4.688 mg/g；出水砷浓度符合世界卫生组织规定饮水砷标准(0.01 mg/L)。

With the current sharp decline in oil prices, the cost advantage of calcium carbide has been greatly reduced.

根据目前的油价大幅下跌，电石的成本优势已大大降低。
