分别采用重量法、蒸馏法和X射线荧光光谱法测定含亚硫酸钙的脱硫灰中硫含量。
The traditional chemical analysis, distillation method and XRF were used to measure the sulfur content in desulphurize slag contained calcium sulfate.
射线荧光光谱法通过建立标准曲线后，可以准确而又快速地检测脱硫灰中亚硫酸钙及硫酸钙总的硫含量。
The XRF method based on standard curve could determine the total sulfur content in desulphurize slag accurately and rapidly.
研究结果表明： 亚硫酸钙含量较多的脱硫灰可用作水泥的调凝剂，并且与二水石膏复掺后的效果更好。
The results obtained showed that the desulphurization residues containing a number of CaSO_3 may be used as a retarder, and be better by adding with gypsum.
在实验室电炉静置煅烧条件下，研究了硫酸钙和亚硫酸钙、含亚硫酸钙的脱硫灰和石膏在水泥熟料煅烧过程中硫的逸放。
The sulfur emissibility during burning cement clinker with calcium sulfate, calcium sulfite gypsum and desulphurize slag that consist of CaSO3 separately were studied in laboratory electric stove.
结果表明：以GB/T176—1996《水泥化学分析法》和GB/T5484—2000《石膏化学分析法》中的基准法即重量法不能准确测定含亚硫酸钙的脱硫灰中的硫含量；
The results showed that the gravimetric method commanded by GB/T176-1996 and GB/T5484-2000 was inaccurate to measure the sulfate content while the distillation method was comparatively accurate.
