1·The results showed that ball-milling treatment and calcining temperature exert an influence on sintering process of HA.
结果表明，球磨处理和粉体煅烧温度对HA坯体的烧结行为均有明显影响。
2·Densely sintering of dolomite ore is difficult because decomposing of carbonate results in forming porous structure during calcining process.
由于白云石在煅烧过程中碳酸盐分解后形成多孔疏松结构，使其难以烧结致密。
3·The experiment results show that with calcining temperature rise the color of ferric red gradually deepened from mauve to chrysoidine , morphology of ferric red also changed.
实验结果表明：随着煅烧温度的升高，铁红颜色逐步加深，由橘红变为紫红，铁红的形貌也发生了变化。
4·The calcining temperature and the grinding time of mechanical-thermal complex activation has little influence on the early strength of coal gangue cement, but has great influence on late strength.
机械-热力复合活化的煅烧温度、粉磨时间参数对掺煤矸石水泥早期强度的影响不大，但对后期强度有较大影响。
5·The carbonate from calcium carbonate, if not removed by calcining may cause foaming in the reactors.
碳酸钙中存在的碳酸根，如果不经煅烧除去，会在反应槽中引起泡沫生成。
