Contact model was established to quantitatively calculate the preparation of cement with different clinkers of varying strength by means of mathematical modeling of blending materials. Reactivity of clinkers from varying kiln system can be assessed by this model to produce cement.

采用混杂材料的数学模拟理论，建立了可以定量计算不同强度的熟料混合磨制水泥的接触点模型，应用该模型方法可以比较不同窑型熟料混合粉磨制备水泥时掺加熟料的活性效应。

Mix the Crystallizing Powder with clear water. Then spread it on the stone surface, and spray a proper amount of clear water to keep the stone wet. Polish with a floor rubbing machine or special crystallizing machine together with a whitening cushion. Always keep the floor wet during and never be too dry polishing. Each operation covers about 3~5 square meters.

将结晶粉加清水调成糊状后均匀涂于石材表面，并喷洒适量清水使石材保持湿润，然后用擦地机或专用结晶机配合白洁垫进行抛磨，（抛磨过程中至终保持地面湿润，切勿过干），每次工作区域大约在3~5平米左右。

The results show that adding water reducer on gypsum before grinding gypsum can cause good grindingaid effect and improve remarkably the dispersing and fluidity of gypsum plaster.

减水剂磨前掺入可显著提高石膏的粉磨效率，提高石膏的比表面积，使颗粒粒度细化；可明显增加减水剂在石膏表面的吸附量与ζ电位，其分散能力大大优于减水剂同掺。

The mainly conclusions in our research are as flowing: tungsten trioxide powders with 100 nm primary particle are obtained by spray drying,calcination and wet milling process, and an average size of quadric particle composed of agglomerated particles is 0.64 μm; tungtsen powders with 39 nm grain size and 60 -100 nm primary particle are produced directly from previous tungsten trioxide using one step reduction in hydrogen at 700℃, and an average size of quadric particle of tungsten powder is 2.91 μm; tungsten trioxide and copper tungstate compound powders with 100 nm - 200 nm primary particle are produced using ammonia metatungsten and copper nitrate as raw materials by spray drying,calcination and wet milling process;the compound powders are transformed completely into tungsten and copper compound powders by reduction in hydrogen at 700℃,in which tungsten grain size is 59 nm and copper grain size is 51 nm; primary particle size of compound powders is 80 - 120 nm,and an average size of agglomerated quadric particle is 1.86 μm; tungsten nitride powders with 35 nm grain size are prepared from tungsten trioxide powders by nitrogen treatment thoroughly in pure ammonia at 650℃, and an average size of agglomerated quadric particle is 0.64 μm in normal temperature.

研究结果表明：采用喷雾干燥—焙烧—球磨工艺可以制备出粒度约为100nm的WO_3粉体，它们在团聚后形成的二次颗粒平均粒度为0.64μm；采用一步直接氢还原方法可在700℃下从上述WO_3粉体制备出晶粒尺寸为39nm的、一次颗粒粒度为60-100nm的W粉体，其二次颗粒的平均粒度为2.91μm；以偏钨酸铵、硝酸铜为原料，采用喷雾干燥—焙烧—球磨工艺可制备出一次粒度为100-200nm的WO_3和CuWO_4混合粉体；采用氢还原工艺可在700℃下将这种粉体完全转变为W、Cu复合粉体，其中W的平均晶粒粒尺寸为59nm，Cu的平均晶粒尺寸为51nm；复合粉体的一次颗粒尺寸为80-120nm，在常温下团聚后形成的二次平均粒度为1.86μm；采用纯氨氮化工艺可以在650℃下由WO_3粉体制得WN，其晶粒尺度为35nm，在常温下团聚后的二次平均粒度为6.4μm。
