Temperature distribution and its time evolution are fundamental physics of arcs occurring during breaking process in electro-mechanic devices, which largely determine contact erosion. Aimed to the highly fluctuating switching arc, we implemented an optical system based on relatively strength of two individual spectrum emitted by the same excited atoms inside the plasma. Light emitted from arc is firstly...
[Objective] This paper focuses on analyzing the energy resources and precipitation trends to the context of global warming in the western Liaoning Province in recent 60 years, where located in the northern hemisphere. Provide the basis study for the adjustment of agricultural structure and full use of energy resources. [Method] Use meteorological data of three cities in western Liaoning Province during...
This paper using the weather station data in rural surroundings which have been not changed near fifty years, and applying the statistical method of serial correlation and inclination rate to analyzes the trend changes of environmental temperature and accumulated temperature in the Western Liaoning rural area. This research providing the proof of climate change study, describing the climate characteristics...
