23 устранять необходимость в
Устранять необходимость вStandard square drive sockets and accessories can be used, which eliminate the need for special equipment.This supposition removes the need to consider the complicated chemical rate equation.Locating the flow test section in the high-pressure feedwater line will obviate the need for other flow measuring devices in that location.The choice of a finite difference technique (versus finite element) averts an interior iteration.API standards often can preclude the need for additional legislation.Русско-английский научно-технический словарь переводчика > устранять необходимость в
