The reference fluid is taken to be a hypothetical substance.

Принимается, что эталонной жидкостью является гипотетиче-

ское вещество.

He seems to have given up this view.

4. Оборот «for + существительное + инфинитив» имеет слово,

обозначающее лицо или предмет, которое вводится предлогом for и при переводе становится подлежащим придаточного предложения. Слово for помогает определить начало русского придаточного предложения, вводимого союзами чтобы или что, в котором инфинитив становится сказуемым.

For this method to be valuable it must be improved.

Чтобы этот метод был полезным, его надо усовершенствовать.

There is a tendency for the method to be used in all the experiments.

Существует тенденция к тому, чтобы использовать этот метод во всех экспериментах.
