The mission, which is made of two spacecraft, is designed to investigate the magnetospheric global processes and their response to the interplanetary disturbances in conjunction with the Cluster mission. The first spacecraft, TC-1 (Tan Ce means "Explorer"), was launched on 30 December 2003, and the second one, TC-2, on 25 July 2004 on board two Chinese Long March 2C. Due to the importance of and success of DSP, both CNSA and ESA approved the extension of DSP. This paper presents DSP mission and some important scientific results made based on the data of DSP.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

Methods: the subjects of the study were the undergraduate students of clinical medicine in Anhui Medical University. The number is about 80. They were randomly divided into two groups with 40 people in each group. There was no significant difference in learning achievement and intelligence test scores between the two groups. The teaching time and place of the two groups of students are basically the same. All students are required to preview the teaching contents in advance. The traditional teaching group was the control group, while the virtual medical technology teaching group was the research group (P<0.05). Results: after comparison, the study group's students' academic performance was higher than that of the control group, and the study group's students' satisfaction with the teaching methods was higher than that of the control group (P<0.05). Conclusion: the effect of applying virtual medical technology in reproductive teaching is better than that of traditional teaching method. The students' test scores are ideal and they have high recognition of virtual medical technology.展开更多
