氧化钙

Slag test indicates that andalusite has no obvious effect on penetration. Slag penetrates along boundaries of bauxite or mullite. Al2O3 from bauxite dissolves into slag to form CA6, anorthite, gehlenite and other low melting phases which precipitate during cooling.

渣蚀试验表明，红柱石时侵蚀无明显影响，熟料液相沿莫来石和矾土骨料晶界向内渗透，氧化铝逐渐浓解与液相、渣中的氧化钙形成CA5和钙长石、黄长石等低熔相，在冷却过程中，钙长石和黄长石从液相中析出。

We understand Sunland manufactures and sells quicklime products; it also operates a trading business of quicklime products to customers as well .

我们了解，目前公司除了销售自己生产的氧化钙产品外，还从其他公司采购氧化钙并直接销售。

The content of calcium oxide is lower than all the other exported slabstone in our country, and has the strongest ability of acid-resistant,weather-resistance.

源于其内在质量优良，氧化钙含量低于我国所有其他出口板石的氧化钙含量，其耐酸、抗风化的能力最强。

The CaO content in ash is related to magnetic petrographic characteristics of coal,and it is possible to predict CaO content in ash with coal macro-petrography.

结果表明：煤灰分中氧化钙含量与其宏观煤岩特征的关系比较密切，用宏观煤岩特征可以预测煤灰中氧化钙的含量。

The results also show that the mechanism of lead capture by CaO involves a chemical reaction between CaO and PbCl2, forming calcium plumbate (Ca2PbO4) as the dominant reaction product.

由於氧化钙被用来除去高温废气中之气态硫化物，因此，氧化钙对氯化铅(PbCl2)的高捕获效率显示其应可用来同时袪除氯化铅和硫化物。

Test results show that the shear strength parameters of the fly ash with high calcium oxide content can make a notable change due to pozzolanic action and frost and thaw cycles, but for the fly ash with low calcium oxide content this phenomenon is not very obvious,and the influence of the frost and thaw cycles can be neglected.

试验结果表明，高氧化钙含量的粉煤灰的强度指标受上述两种作用的影响显著；低氧化钙含量的粉煤灰的强度指标在凝硬作用下也有所提高，但基本不受冻融作用的影响；干贮粉煤灰的渗透系数受凝硬和冻融作用的影响较小。

Through the study of the crucible manufacture and its application in strong reducing atmosphere it was found that the used densified CaO crucible could decrease the absorption of calcium by the refractory and increase efficiency of calcium.

通过对氧化钙坩埚制造和使用的研究，发现用使用过的致密氧化钙旧坩埚可以减少坩埚对钙液的吸收，提高了钙利用率。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
