In the present investigation, the principal phases in alunite rock from Ping-Yang and Lu-Kiang have been studied. They were α-quartz, hematite and alunite. The latter was a mixed crystal of the type (K,Na)Al_3(SO_4)_2(OH)_6. In alunite rock, α-quartz and hematite were embeded in the alunite phase. In order to elucidate the nature of the alunite phase in alunite rock,the lattice constants and structural parameters of sodium alunite were determined and compared with those of potassium alunite.

本文,对平阳和卢江矾石矿中的各个物相进行分离、鉴定并对它们的分布情况进行了研究.矾石矿中主要的物相为α-石英、赤铁矿和明矾石物相(K,Na)Al_3(SO_4)_2(OH)_6,后者为混晶体物相.显微照相指出,矿石中的明矾石物相为一连续的物相,而α-石英和赤铁矿则夹杂其中. 为了进一步阐明明矾石物相,曾对钠明矾石的点阵常数和结构参数进行了测定,并对矾石中钾、钠离子的配位情况进行了比较.根据点阵常数,对矿石中明矾石物相的含钠率进行了推算.

The rate of formation of carbonaceous deposits on cadmium-calcium-phosphate catalysts was determined by metns of a quartz spring balance, and the results were interpreted.

为了探讨结焦因素对乙炔水合磷酸镉钙催化剂稳定性的影响,本文应用石英弹簧秤在常压微分流动体系中,于300-420℃和250-450℃的温度范围内分别研究了乙炔和乙醛在这种催化剂上的结焦动力学行为.找出抛物线经验方程表达了乙炔的结焦动力学.认为过程吸附平衡迅速建立,吸附层的结焦分解为其控制步骤,并以多层沉积的焦上结焦机理和由于焦层扩散阻滞的影响而使结焦速度同焦量成反比的假设,讨论了经验方程式的物理意义.实验表明,乙炔催化水合伴随有强烈的乙炔和乙醛在催化剂上的焦化作用.乙醛缩聚的沉积物发现有进一步的脱羧分解过程.催化剂表面吸附的水分子能显著抑制催化剂的焦化作用.乙炔结焦活化能比水合活化能大约低10Kcal/mol的数量级.

By different kinds of experimental methods we got some new understanding for the action and mechanism of bonding clay for high strength shell mould. Then we recommend the alumina, instead of silica powder and other kind of clays, to be used for high strength shell mould production, and thus substantially improve the high temperature characteristics of the shell mould.Instead of ammonium chloride the polymerism alumium chloride is used as hardening agent, thus we greatly improve the working condition of the workers...

By different kinds of experimental methods we got some new understanding for the action and mechanism of bonding clay for high strength shell mould. Then we recommend the alumina, instead of silica powder and other kind of clays, to be used for high strength shell mould production, and thus substantially improve the high temperature characteristics of the shell mould.Instead of ammonium chloride the polymerism alumium chloride is used as hardening agent, thus we greatly improve the working condition of the workers and considerably reduce the corrosion of the equipments. Adopting the new technology in which the waterglass and aluminum chloride mixing respectively with alumina and silica are used as paints,and they are painted to the mould alternately, thus we put an end to the old repeated processes of air hardening and chemical hardening, and raise up the productive efficiency.

通过多种试验方法,对高强度模壳用增强剂粘土的作用机理初步有了新的认识,并推荐铝矾土代替石英粉和其他粘土用于高强度模壳生产,大大提高了模壳的高温性能。 采用碱式氯化铝代替氯化铵作硬化剂,大大改善了工人的劳动条件,减少了设备腐蚀;采用水玻璃和碱式氯化铝分别与铝矾土和石英粉配制的涂料交替浸涂的新工艺,革除了自然干燥与化学硬化两道多次重复的工序,从而提高了生产效率。
