本文分两个部分论述了铝酸钡在实验室条件下的研制和其在铝酸钠溶液中的脱硫应用.首先,利用贵州省织金县储量丰富、品位高的重晶石和毒重石与自产氢氧化铝在一定温度下混合焙烧可以制得纯度达95﹪以上的可溶性铝酸钡.其次,该自制铝酸钡用于铝酸钠溶液脱硫时,与氢氧化钡脱硫相比有两大突出优点:一为铝酸钡与溶液中SO<,4><>2-的结合能力强于CO<,3><2->,在某种条件下甚至不与CO<,3><2->反应,而氢氧化钡进入铝酸钠溶液时先表现为与CO<,3><2->的强烈结合,排除SO<,4><2->的有效反应则滞后;二为铝酸钡的循环使用工艺简单,技术条件单一,原料单耗低,氢氧化钡的循环使用技术条件则较复杂.

本文首先对喷气包缠纺和喷气涡流纺的加捻过程进行了描述,加捻过程的描述是成纱机理研究的基础。然后对喷气涡流纺纱成纱机理的自由端特征进行了分析,并利用PHOENICS软件对喷嘴中气流的运动进行了模拟,以及利用高速摄影对纤维加捻过程进行了拍摄,同时,结合成纱结构进一步说明了成纱机理。认为喷气涡流纺具有明显的自由端纺纱特征,但中心仍有未断裂的一定量的连续纤维,因此,喷气涡流纺可以看成是部分自由端纺纱、半自
