The paper is devoted to teaching language for specific profession-related purposes to engineering students and lecturers. The authors associate the teaching process with using the metaplan technique as the information basis of oral speech. The paper characterizes heterogeneous sign elements of a metaplan as material and ideal teaching media and reveals the mechanism of expanding compressed metaplan information. The mechanism is based on developing speaking skills in lexico-grammatical and semantic expansion of verbal information and intersemiotic translation of extralinguistic information into speech register. The authors have developed a set of exercises with due consideration of actual second-language speaking situations encountered by engineering specialists.
The paper describes the research into the effect of the energy supplied to the conductor at the time of explosion on the particle size distribution of aluminum powders obtained. Aluminum powders consist of at least three fractions with the average particle size of 20-100 μm, 1-5 μm, and 50-900 nm. The yield of each fraction and average particle size are determined by the level of energy supplied to the conductor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
