查询词典 spectrophotometer

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.
