硬石膏

No coexisting liquid-and gas-rich fluid inclusions were found during quartz petrogaghy microscope observation, the lack of acid hydrothermal alteration mineral assemblages (e. g., alunite, kaolinite, barite, and anhydrite, etc), the measured bulk gas component data of pyrite-and quartz-bearing fluid inclusions distributed cluster on the volatile-temperature diagram, the similarities of the aqueous geochemical compositions among individual low-salinity fluid inclusion decrepited pits detected by SAM/AES and the sulfur isotope profile of a sirngle pyrite stain smoothly changed implied that the ore-forming fluid phase seperation didn′t, contribute significantly to Duolanashayi gold deposit

石英显微观察未发现有共存的富气相和富液相流体包裹体、金矿床明显缺乏原生酸性蚀变组合(如明矾石、重晶石及硬石膏等)、黄铁矿及石英所含流体包裹体实测结果在气相组成-温度相关图上分布较为集中，黄铁矿所含单个低盐度流体包嘉体液相组成俄歇电子能谱分析结果差别不大以及单颗粒黄铁矿硫同位素离子探针线扫描结果变化不明显等宏观与微观地质特征均说明流体相分离对形成多拉纳萨依金矿床的贡献不大

In the porosity reservoir with anhydrite, the formation water is rich in sulfate and poor in heavy metal ion.

在与硬石膏的多孔性水库，形成水在重金属的离子的硫酸盐和贫寒上是富有的。

We have already developed the technologies of our own new feature as following:(1) Surface modification of Ultra-fine anhydrite powder.

我们选择这一项目进行攻关既具有坚实的理论和试验依据，也具有原创性，将对硬石膏矿产业和塑料产业的发展产生极其深远的意义。

Taking natural anhydrate(anhydrous gypsumⅡ) as major raw material,adding composite activator for modification to adjust setting time,flexural strength and compression strength,then mixed and milled with proper amount of composite water-retention agent,fly ash and air entraining agent to obtain plastering gypsum .

以天然硬石膏为主要原料，掺加复合激发剂进行改性处理，调节凝结时间及抗折、抗压强度，然后辅以适量复合保水剂、粉煤灰掺合料、引气剂等，磨细混匀后即得到抹灰用的粉刷石膏。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
