Mineral trioxide aggregate ( mta ) is a new pulp capping material , which allows dental pulp to recover and promotes dentin bridge to form more effectively than some other pulp capping materials , for example , calcium hydroxide or formocresol , et al 摘要三氧化物多聚体是一种新的盖髓材料，可以用于直接盖髓或活髓切断术，牙髓组织对其反应良好，尤其是修复性牙本质的形成状况优于氢氧化钙、甲醛甲酚等盖髓材料。
The result shows the high performance concrete ( hpc ) with low w / b normally has denser surface , consuming the ca ( oh ) 2 by pozzolanic reaction and low permeability , which are allowed to restrain effectively the neutralization to decrease the cracking for better durability on concrete 结果显示，以低水胶比之高性能混凝土，介面颇为致密，卜作岚反应消耗氢氧化钙，低渗透性等直接有效的抑制混凝土的中性化，可减低裂缝机率，进而提升混凝土的耐久特性。
In the case of sorbents prepared without naoh addition , both the ca utilization and the so2 capture increased with increasing slurrying temperature and varied with the bfs / hl weight ratio ; however , in the case of sorbents prepared with naoh addition , their ca utilization in creased to a level that was nearly independent of the slurrying temperature and the bfs / hl weight ratio 未添加氢氧化钠的炉石氢氧化钙吸收剂与二氧化硫反应的钙利用率与二氧化硫捕捉率随浆化温度的增加而增加，且随炉石氢氧化钙重量配比而改变；添加氢氧化钠后，吸收剂之钙利用率几乎相同，不受浆化温度与重量配比影响。
Abstract : the effects of calcium hydroxide purity , sodium hydroxide concentration , and chlorination temperature on effective chlorine content of calcium hypochlorite have been tested . the results indicate that the higher calcium hydroxide purity is , the higher effective chlorine content of calcium hypochlorite is , that when sodium hydroxide concentration is 30 % , and chlorination temperature is 20 , the effective chlorine content of calcium hypochlorite is the highest 文摘:测试了氢氧化钙纯度、烧碱浓度和氯化温度对漂粉精有效氯含量的影响.结果表明，氢氧化钙的纯度越高，漂粉精的有效氯含量越高；烧碱浓度为30 、氯化温度为20时，漂粉精的有效氯含量最高
