It is concluded from the investigations that evaporation duct propagations and other tropospheric duct propagations become very complicate multi - discipline problems at present time including em theory , atmospheric science and applied science etc . , and one of the tough and hot issues in the field of tropospheric propagation 经过多年的研究，目前蒸发波导传播等电波传播问题成为非常复杂的多学科问题，涉及到电磁波理论、大气科学和应用科学等，成为对流层传播研究中的一个热点和难点问题。
By simply comparing the aspects of the total founding , management , scientists strategies of atmospheric science research between us and china , this paper indicate that of all main aspects of atmospheric science research activities china is keep behind of the us , not only in research products , resources of scientists and service supporting science , but also management system and scientists strategies as well 摘要通过对中美两国大气科学研究在经费、管理、人才战略等方面的一些简单比较，说明我国大气科学研究，无论在成果、人力物力资源、管理体制和人才战略思想等方面，均与美国有不小的差距。
