Scientific and technical contacts between nations* have necessitated the publication of various language textbooks, manuals and reference books. Particularly important among them are multilingual scientifio and technical dictionaries. This English-German-French-Dutch-Russian Dictionary of Scientifio and Technical Terms contains some 9000 entries. The main fea ture of the Dictionary is that it includes first and foremost general scientific terms needed by an engineer working in any branch of science and technology. Besides, the Dictionary includes the basic terms used in physics, mathemat ics, the fundamentals of electrical engineering and chemistry, and also the most essential terms pertaining to manufacturing processes. machine design, testing methods, etc. The Compilers were confronted with a difficult task, as nowadays science and technology are developing rapidly and the minimum scientific and tech nical vocabulary required by a specialist is increasing accordingly. The Compilers have taken special pains to include the entire basic mod ern technical vocabulary, omitting superfluous words and phrases. They have tried to solve this problem by selecting mainly those scientific and tech nical terms which constitute the basic of a specialised vocabulary. There fore, the Dictionary includes the vocabulary pertaining to general study courses in mathematics, physics and chemistry, and also in electrical engi neering. electronics and machine design, given in technical colleges irrespect ive of their specification. This lends the Dictionary an "all-purpose" char acter, making it equally useful to scientists and engineers of different countries, who have graduated from colleges with different curricula.

In the last few decades civil engineering has undergone substantial technological change which has, naturally, been reflected in the terminology employed in the industry. Efforts are now being made in many countries to bring about a systematization and unification of technical terminology in general, and that of civil engineering in particular. The publication of a multilingual dictionary of civil engineering terms has been necessitat ed by the expansion of international cooperation and information exchange in this field, as well as by the lack of suitable updated bilingual dictionaries. This Dictionary contains some 14.000 English terms together with their German, French, Dutch and Russian equivalents, which are used in the main branches of civil engineering and relate to the basic principles of structural design and calculations (the elasticity theory, strength of materials, soil mechanics and other allied technical disciplines); to buildings and installations, structures and their parts, building materials and prefabrications, civil engineering technology and practice, building and road construction machines, construction site equipment, housing equipment and fittings (including modern systems of air conditioning); as well as to hydrotechni cal and irrigation constructions. The Dictionary also includes a limited number of basic technical expressions and terms relating to allied disciplines such as architecture and town planning, as well as airfield, railway and underground construction. The Dictionary does not list trade names of building materials, parts and machines or the names of chemical compounds. Nor does it give adverbial, adjective or verbal terms.
