电磁海流计传感器性能的比较

电磁海流计在海洋调查和研究中起着非常重要的作用。当前被广泛应用的电磁海流计的传感器基本采用三种不同的结构形式：球形结构、盘形结构和环形结构。而三种结构形式的传感器具有各自不同的技术参数和性能。文章对不同结构形式电磁海流计传感器的特点进行简要的比较和分析。我们在研制和使用电磁海流计时，应根据不同的设计要求和特定的应用环境和条件，选择适当形式结构的传感器，力求得到良好的结果。     

Fifth Anniversary of GEOCHIM 2003／UNESCO “Postgraduate certificated training course in geochemical exploration methods and their environmental applications”

It has been a tradition to organize very successful UNESCO Postgraduate Courses on Geochemical Prospecting Methods in the former Czechoslovakia from mid 70‘s. The first certificated course--GEOCHIM PRAHA UNESCO 1975 was launched on September 5, 1975 and lasted till October 25, 1975. Since that time this course has been organized biannually by the Czech Geological Survey in Prague together with the Dionyz Stur Geological Survey in Bratislava and sponsored by the Division of Earth Sciences (UNESCO/Paris) and the International Association of Geochemistry and Cosmochemistry (IAGS). The course was specialized on both theoretical and practical training in classical geochemical prospecting methods. A team of internationally experienced geoscientists as Drs.J.Pokorny, F.Mma, J.Manour, V.Lomozova Z. Sulcek,I. Rubeska, A.Spackova, V.Sixta, J.Juna,J.Veselu, J.Dornic and others, co-ordinated by Dr. Zdenek Pacal from the Czech Geological Survey in Prague has soon earned high international reputation and the GEOCHIM CSSR UNESCO Postgraduate Course developed into one of the most successful Postgraduate Training Programmes of UNESCO.
