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。
