理论物理界的关注,并被称为空间的基础
物理学;进而,各国的空间局逐渐将微重力科学称之为空间的物理学,但空间的物理学并没有改变微重力科学的基本内容.随着国际空间站逐渐组装完成,空间站成员国正抓紧安排计划中的微重力科学实验项目,预计会在2016年以前取得一批重大成果.另一方面,需要在专门卫星上进行的引力理论和广义相对论验证实验,也在安排之中.在美国进行GP-B卫星计划后,探测引力波的LISA计划受到广泛的关注.空间的物理学将在促进重大学术成果和开拓新的技术发展两方面不断取得进展.

Abstract In recent years fundamental physics in a microgravity environment has attracted much attention from theoreticians in the international community, and has been given the name of fundamental physics in space. Furthermore, microgravity science has gradually become known as physics in space amongst the space agencies of the chief space countries. However, physics in space has not changed the contents of microgravity science. As the International Space Station nears completion, its member countries are working hard to schedule the microgravity science missions, and important results should be obtained before 2016. On the other hand, plans for space tests on the theories of gravity and general relativity on board special satellites are under way. After the GP-B satellite experiment by NASA, the LISA program for space measurement of gravitational waves aroused broad interest. Physics in space will certainly make great strides in both promoting important scientific achievements and in developing high technology for applications.
