Structural characteristic and surface mor-phology of the as-deposited films was analyzed by using X-ray photoelectron spectroscopy, transmission electron microscopy, X-ray diffractometer and atomic force microscopy. It was found that the films represented a two component system comprising Te particies dispersed in an amorphous TeO2 matrix. The dispersed Te particies were in a crystalline state. The TeOx films showed a finely granular structure and a rough surface. Results of the statie recording test showed that the TeO_x films had good writing sensitivity for short-wavelength laser beam (514.5 nm). Primary results of the dynamic test at 514.5 nm were also reported. The TeO_x films were suitable for using as a blue-green wavelength high density optical storage medium.展开更多

The results show that the related scholars pay more and more attention to the study on the performance appraisal of land consolidation, and the number of papers increases overall; the core journals on agriculture,land,environment,economy and other areas,put increasing emphasis on the publishing of papers concerning the performance appraisal of land consolidation; in terms of citation frequency of papers,the impact of papers is wide,but the depth is not enough; the research methods are increasingly diversifying,and the research topics are concentrated; the foundation support is yet to be strengthened for research.展开更多

Therefore it is of significance to research on the relationship between atmospheric temperature and earthquake, as has been reported. A preliminary analysis on the data collected in Yunnan Province shows that there exists an obvious relationship between the atmospheric temperature anomaly and a great展开更多
