The TiO2 thin film on quartz glass is prepared by Liquid Phase Deposition method. The thicknesses of the films are determined by a spectrophotometer. The influence factors on the thicknesses such as ultrasonic vibration, times of sedimentation, sedimentation time and concentration of TiO2 colloid are investigated. A mathematical model of sedimentation is set up on the basis of gas adsorption theory.A photocatalytic continual tub reactor is set up.

本项目以溴化锂溶液和氨水溶液作为研究重点，主要内容包括：对添加剂作用下的溴化锂溶液和氨水溶液表面张力进行了实验研究，发现添加剂对两种溶液表面张力的影响呈现出不同的性质；利用表面吸附动力学原理，对溶液的表面张力及动态表面张力进行了理论分析；利用激光阴影法对溴化锂溶液静池吸收过程中马拉戈尼对流的形成进行了可视化研究，并进而发现蒸汽添加剂比液体添加剂对吸收具有更好的强化效果；利用实验方法对溴化锂溶液垂直降膜吸收进行了研究，并从其基本方程出发得出了影响添加剂强化效果的主要因素；同时，也对添加剂对氨水鼓泡吸收的影响进行了实验研究；最后，对添加剂的强化机理进行了分析，即对于溴化锂溶液来说，添加剂对溶液吸收的影响主要体现在对吸收界面吸附特性的影响上，无论是气体添加剂还是液体添加剂，都有可能对溴化锂溶液吸收起到强化作用；对于氨水溶液而言，添加剂的影响主要还是体现在&盐析&作用上，当氨水浓度较低时，添加剂有可能对吸收起到强化作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
