The special interest in electronics all over the world is due to its decisive role in the scien tific and technical progress now taking place in all fields of modern technology. Electronics also plays a decisive role in the development of science, providing as it does the technical basis for various scientific experiments. The role of electronics in the development of the world's culture also deserves a special mention. That is why it is hoped that the English-German­ French-Dutch-Russian Dictionary of Electronics, which contains some 9.000 entries and is jointly published by Kluwer Technische Boeken, B.V. (Deventer, Holland) and Ruski Yazyk Publishers (Moscow, USSR) will be favourably received. In accordance with existing internation­al tradition, the term «electronics» covers several fields known in Soviet classification as elec tronics proper, radio engineering, and wire communication. The entries included in this dictionary have been selected in accordance with the international understanding of the term «electronics».
