Упражнения к § 38 – 45

Переведите на русский язык:

1. Oxides and sulphides, some metal alloys as well as chemical elements are called semiconductors. All of them conduct electric current worse than metals do. It is from this fact that semiconductors derive their name. They do possess many wonderful properties. Some of the devices using semiconductors for example let electric current pass through them only in one direction and do not conduct it at all in the other. Soviet scientists do all they can to make the utmost use of semiconductors. 2. A speed-up in the development of the chemical industry is a highly important factor in increasing the output of consumer goods at a much greater pace. 3.
