30 сам по себе
Сам по себе - in itself, by itself; on one's own, in its own right, per seThe fiber metal pad in itself is a good insulator because of its porosity.Use can be made of very stable organic fluids which on their own have unsuitable thermodynamic properties - e.g., alkanes and perfluorocarbons.Coal gasification per se is not a new development; it has been in use for many years.It is felt that each [factor] is a complex topic in its own right, deserving individual treatment in depth.Русско-английский научно-технический словарь переводчика > сам по себе

alkane
Paraffins. A homologous series of saturated hydrocarbons having the general formula CnH2n+2. Their systematic names end in -ane. They are chemically inert, stable, and flammable. The first four members of the series (methane, ethane, propane, butane) are gases at ordinary temperatures; the next eleven are liquids, and form the main constituents of paraffin oil; the higher members are solids. Paraffin waxs consists mainly of higher alkanes. (Source: UVAROV)
