1·A series of carbonation test of calcined dolomite slurry at low temperature for preparing metastable solution of magnesium bicarbonate is made.

对白云石碳化制取碳酸氢镁介稳溶液的条件进行了系统的试验，发现温度对碳酸氢镁溶液影响显著。

2·In this paper, the effects of calcination temperature, holding time and content of dolomite on the strength and expansion rate of cement mixed with calcined dolomite are investigated.

研究了白云石的煅烧温度、保温时间以及掺量等对水泥物理性能和膨胀行为的影响规律。

3·The dolomite is calcined to form the mixture of calcium oxide and magnesia, then the mixture is extracted by ammonium chloride solution and ammonium sulfate solution respectively.

通过对煅烧后的白云石中所含的氧化钙和氧化镁，分别采用氯化铵溶液和硫酸铵溶液进行浸提，使其中的钙、镁得到较好的分离。

4·Research on the composite magnesia cement of the caustic dolomite and the calcined magnesite;

指出欠烧或过烧菱苦土的采用是造成氯氧镁水泥硬化体胀裂的根本原因。
