The national quitline provides residents in China's Mainland with free telephone smoking cessation services. Of 8260 callers from December 1, 2009 to May 31, 2012, the study included 1049 callers to the non-automated service who gave basic information during the call. Of the 1049 live-access callers.展开更多

It is revealed that the RS characteristics show strong dependence on technological parameters mainly by altering the defects （oxygen vacancies） in the film. The sample with thickness of 2Onto and Ar/O2 ratio of 12：3 exhibits the best RS behavior with the potential of multilevel storage. The conduction mechanism of all the films is interpreted based on the filamentary model.展开更多
