您要查找的是不是：
- anhydrite gypsum 硬石膏质石膏
- Under the circumstances, gypsum or anhydrite could accumulate to form beds many meters thick, without any co-precipitation of halite. 在这种环境下，石膏或硬石膏可以堆积成许多米厚的岩层，而没有任何石盐伴生沉淀。
- And water rich organic acid discharged from rock when gypsum changed into anhydrite, which dissolves part of the rock and form secondary porosity. 同时，石膏向硬石膏转化时，排出大量富含有机酸的水，有利于形成次生孔隙带。
- Hemihydrate can be used instead of gypsum. 半水物硫酸钙可以用来代替石膏。
- A dense translucent, white or tinted fine-grained gypsum. 雪花石膏一种不透明的、白色或浅色的纹理细密的石膏
- The gypsum slurry is pumped into a diked area. 我们用泵将石膏料浆打到一块用堤围起来的空地中。
- This method of handling gypsum is satisfactory. 这种输送石膏的方法是令人满意的。
- At the conditions of calcination of anhydrite mixed with some gypsum,and adding stimulated slag and compound stimulatives,activation of anhydrite can be changed. 对掺加一定量二水石膏的硬石膏混合物料进行煅烧,并添加激发矿渣和复合激发剂,可改变硬石膏的活性;
- Phosphogypsum is calcined into anhydrite at high temperature and can be used as the raw material of compound silicon cement and then made into floor gypsum. 将磷石膏在高温下煅烧成无水硬石膏,在合适的激发剂作用下,使之达到复合硅酸盐水泥质量要求,即制成地板石膏;
- Gypsum is the product of the process. 此方法的产物为石膏。
- Up to 5% of gypsum can be added to cement products. 水泥成品中最多可以添加5%25的石膏。
- Huoxingbaitu, bentonite series products, gypsum. 活性白土，膨润土系列产品，石膏。
- Locally dolomite and anhydrite are important as cements. 局部地方白云石和硬石膏也是重要的胶结物。
- Gypsum line to avoid parch and split up. 石膏线避免干裂松动。
- Gypsum can be used as a soil conditioner. 石膏可以用作土壤改良剂。
- Gypsum and halite are simply thinned or removed altogether. 石膏与岩盐则逐渐变薄或完全被溶解掉。
- The result shows, for this composite cement system, retarding action of dihydrate gypsum is more obvious than that of anhydrite, meanwhile, anhydrite tends to cause setting time short and water needed increased. 结果表明：二水石膏对该种复合体系水泥的缓凝作用比硬石膏明显，硬石膏易引起复合体系水泥急凝和需水量增大。
- Thickeners were introduced for separating the acid and gypsum. 用稠厚器来分离酸和石膏。
- Gao Qiang waterproofing-walled panels, gypsum products. 高强防水隔墙板、石膏制品。
- The anhydrite caused spherulite size of PP diminishing,the quantity increasing. 硬石膏的加入使得球晶尺寸减小,数量增加。
