В отличие от русского языка в английском языке одно и то же слово может выступать в предложении в качестве разных частей речи. Так, в данных ниже предложениях слово water является существительным (1), глаголом (2), играет роль прилагательного (определения) (3), является частью сложного слова (4).

1.Water is necesarry for life.- Вода необходима для жизни.

2.Water the flower-bed, please.-Полей (те), пожалуйста, клумбу.

3.Water mills served a source of energy.-Водяные мельницы служили

источником энергии.

4.water-supply system-система водоснабжения

water-proof watch-водонепроницаемые часы

Значение подобных слов и их перевод на русский язык зависят от того, каким членом предложения они являются. Они могут быть подлежащим, сказуемым (или его частью), определением, обстоятельством. Функцию слова помогает определить твердый порядок слов в английском предложении и контекст.

High- Frequency Current

 

Alternating current with frequency of 50 c/s is widely used in industry.Therefore this frequency is called an industrial frequency and the current, an industrial frequency current.

During sound transmission, current flowing in telephone wires changes with the frequency of sound oscillations, which ranges from 50 to 10 000 c/s. The currents of such frequensies are called audio- or low-frequency currents.

Radio transmission is based on the use of alternating currents with frequencies of hundreds, thousands, millions and even tens of million cycles per second. These currents called high-frequency currents are produced by means of an oscillatory circuit consisting of a coil and a capacitor. Moving along the turns now in one direction now in another, the electric charges oscillate in an oscillatory circuit.

 

By what means are high-frequency currents obtained?
