First, read the following text, completed 1 ~ 4 questions. China's new generation of artificial solar experiment device The world's leading generation of new generation of Chinese fusion nuclear fusion device EAST28 successfully completed the first of its kind to test the electrolysis and obtain a current of 200 kA and a time close to 3 seconds of high temperature plasma discharge. In an interview with Xinhua News Agency reporter Li Jiangang, the director of the plasma institute of Chinese Academy of Sciences in charge of this project, said that experiments have achieved a device with a high temperature of 100 million degrees, a plasma built-up, and a circular cross-section discharge
