A regression equation describing the quantitative relation between foaming index and slag composition has been obtained.
得出炉渣起泡指数与炉渣光学碱度、渣中Ａｌ２Ｏ３及ＣａＦ２含量间的回归方程。
The foaming behaviour of CaO-SiO2-Al2O3-FeO slag system during its reduction process showed that the foaming ratio of the slag was influenced by the rate of the generated gas as well as the foaming index of the slag.
对ＣａＯ－ＳｉＯ２一Ａｌ２Ｏ３－ＦｅＯ熔渣在石墨还原过程中的起泡行为的分析表明，熔渣的起泡率受渣中气体的产生速度及熔渣的起泡指数影响；熔渣的起泡指数随渣中气泡直径的增大而减小；随熔渣碱度的减小，泡沫渣的平均寿命延长，泡沫化愈稳定。
Based on the experimental results and calculated physical properties of the CaO-SiO2-Al2O2-FeO slag system,an empirical equation was obtained from dimensional analysis to predict the foaming index for the slag system as follows: ∑= 164.
通过对石墨还原ＣａＯ－ＳｉＯ２－Ａｌ２Ｏ３－ＦｅＯ熔渣中ＦｅＯ过程起泡指数的因次分析，得出影响渣的起泡指数∑的因素有熔渣密度ρ，粘度μ，表面张力σ及重力加速度ｇ。
The evaluation of real estate bubble extent is to reflect the bubble by deviation between price and value so as to provide basis of avoiding bubble\'s expansion and promoting healthy development of cities\' real estate market.
本文的主要工作:一是建立了城市房地产市场泡沫程度评价指标体系;二是利用属性层次模型(AHM)确定指标权重,利用指标值与泡沫临界值之比确定单项指标泡沫指数,通过对加权综合指数进行Ward聚类判断泡沫程度,建立了城市房地产市场泡沫程度评价模型;三是通过对中国35个大中城市进行实证研究,发现房地产泡沫问题普遍存在,并且在不同的城市严重程度和表现形式有明显差别。
