查询词典 detect

But, because of the complexity of the dye molecule, there has been short of detailed comprehension in its photocatalytic degradation process. The key problem is difficult to detect the intermediates clearly. In this paper, the photocatalytic degradation of azo dye Congo red in water solution was investigated on UV irradiating TiO2 in the homemade reactor. The optimization conditions were determined and then the rate of decolorization, COD decrease, yield of CO2 and varies pH of aqueous solution during illumination were detected; The varies of the possible intermediates during degradation process were monitored with UV-VIS spectrum and HPLC. The possible mechanism of Congo red photocatalytic degradation is discussed combined with the data of MS.

This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.
