提出了一条有效利用天然石膏生产硫酸钾的清洁生产新工艺，通过该方法，可将天然石膏和碳酸氢铵变为具有更高价值的硫酸钾和氯化铵。

The results indicate that anhydrite/PP composites is sensitive to the shear rate, not temperature ,and itrs the typical pseudo-plastic fluid in the experiment temperature range.

本研究中所选的填充材料是硬石膏，硬石膏是硫酸盐矿物，其主要成分是CaSO ，广泛分布于因蒸发作用所形成的盐湖沉积物中。

Low Dilatability and great waxiness,its tenacity is twice more than common gypsum its the ideal material forodontology model

可塑性的石膏，韧性比一般超硬石膏大二倍，是医学齿科模型的理想材料。

The effect of pH values on the Ca2 + concentration and properties of gypsum particleboard was studied.

It is found that the concentration of sulfuric acid in liquid and the reaction temperature are the most sensitive factors for this process. Increasing the ratio of solid to liquid is disadvantageous for growth of crystals even though it does not effect obviously for the rate of dehydration of FGD gypsum. On the other hand,the more closed to the neutral range of pH value the liquid is adjusted,the better stability of the α-form calcium sulfate hemihydrate appear,the more favorable for modification of crystal habit the process is made.

研究中发现pH值和盐溶液浓度是影响FGD石膏脱水速度最敏感的因素，固液比虽然对脱水速度影响不大，但固液比增大对晶体生长和习性改良不利。pH值愈接近中性范围，愈能增强α半水石膏结晶在液相中的稳定性，有利于结晶习性改良。
