A computer program based on Matlab is developed and optimized. The fitting errors are analyzed with theoretical data  which gives very high accurate results. A program is applied to fitting the measured photometric spectra of ion sputtered zirconia and silica thin films in 200-850nm spectra range. The thickness is verified with the method of grazing x-ray diffraction. With the thickness known  the optical constants of zirconia films near the absorption range are obtained with single-wavelength method. As a result  quite good fitting results are obtained with high accuracy. Finally  an ultraviolet (UV) high-pass optical filter is designed with optical constants extracted by this method. The transmission and reflection spectra of the filter are measured and compared to designed spectra. A good coherence was derived.   Corrosion effect of allylthiourea on bulk nanocrystalline ingot iron in diluted acidic sulphate solution 期刊论文  OAI收割 Electrochimica Acta, 2007, 卷号: 52, 期号: 12, 页码: 3950-3957 C.
