An effective algorithm is presented for the working voltage of DGAC using this model. The working voltage is nearly related to the geometric parameters of DGAC, the sensitivity of the circuitry and the number of discharges. Computing results confirm that the working voltage increases with the ratio of the radius of the anode to that of the cathode. The number of discharges follows the similar rule.展开更多

The first-class university culture is very important to the construction of the "double first-class". Therefore, our country should bring the university cultural construction into the big pattern of the "double first-class" construction, guide the construction of the university cultures with the socialist core values, strengthen the cultural confidence, inherit the Chinese excellent traditional cultures, pay attention to the rational exchange of the multicultural cultures, highlight the Chinese characteristics of the first-class university cultures, and realize the dream of the Chinese nation of a power of the higher education.展开更多
