Основа - basis, foundation, framework; backbone (хребет); background (для сравнения, анализа)The basis of methods for estimating RNA content is the measurement of optical density.Indeed, the agricultural system represented by forage crops and the ruminant animals that feed on them can be said to be the backbone of the nation's agricultural economy.With the analysis and presentation of data pertaining to fixed geometry turbine casing as a background, the application of the same approach to two optional configurations of mechanically simple variable geometry casings will be shown.Русско-английский научно-технический словарь переводчика > основа
