哈雷彗星每七十六年进入太阳系一次,这次(指1986年)哈雷彗星进入太阳系是本世纪的第二次,也是最后一次。世界各国的科学家对此都非常重视,并尽可能地用现有的技术对它进行探测,以便更多地了解它的物理、化学及结构组成等诸方面的情况。为此,苏联、欧空局、日本等国相继发射了哈雷探测器,法国、东德、西德等许多国家也为这些探测器做了大量的工作,下面介绍 Halley’s comet enters the solar system once every seventy-six years. This time (referring to 1986) Halley’s comet’s entry into the solar system is the second and final of this century. Scientists in all countries of the world attach great importance to this and probe it as much as possible using existing technologies so as to learn more about its physical, chemical and structural composition. To this end, the Soviet Union, the European Space Agency, Japan and other countries have launched the Harai detector, France, East Germany, West Germany and many other countries have also done a lot of work for these detectors, the following
