At long last,after two decades of endeavor,China’s first high energy astrophysics research probe is about to take of f.The 2.5-ton Hard X-ray Modulation Telescope(HXMT),which is set to be sent 550 km above the ground early2017,will be carrying a trio set of detectors to gather X-rays emitted by black holes and neutron stars in the 1-250ke V band,and enable Chinese scientists to explore the distribution and property of these mysterious sources–with their own data,for the first time in history,in the next four years or more.In August,BCAS reporter XIN Ling had the privilege to meet astrophysicist ZHANG Shuangnan of the Institute of High Energy Physics(IHEP),Chinese Academy of Sciences who is now principal investigator of the HXMT project.During the interview,ZHANG talked about the telescope’s research missions,potential challenges in orbit,as well as its history and lessons to be learned in developing one of the nation’s first science satellites.  相似文献

The widespread application of new technologies, while empowering women with new opportunities, might also put them at disadvantage. For example, in comparison with males, the application of AI might be more likely to cost them their jobs. Meanwhile, women are missing out the opportunity to participate in the policy-making process – they are absent from the table. If no change is made in the current policies, we will miss the goal to achieve gender equality, the fifth of the 17 Sustainable Development Goals set for UN's 2030 Agenda for Sustainable Development, warned elite women scientists with the Organization for Women in Science for the Developing World(OWSD). What shall be done now? How can we make a difference? They are in action to help.  相似文献

Many people would agree that teaching writing is much more difficult than teaching other language skills. My experience of teaching Englishin senior high school has proved that it is true. In each class of high schools, all the language skills are taught by one teacher. So the teacher is the very person who has the right to say that writing is the students’weakest point. It may be because writing is intimately related to the other language skills. One re- ads a text to write answers to quest…  相似文献
