21. Прочитайте и переведите предложения, обращая внимание на то, что запятая здесь носит разъяснительный характер, и в этом случае ее удобно переводить словами: а именно, например, что является и т.Д.

1. An alternative mode of stabilization, by negative substituents, is also possible.

2. This difficulty, of making a machine, is always extremely hard to resolve.

3. Using less glass, a costly ingredient, such structure weighs only 30 pounds as compared to 33.5 for types in current use.

4. The amount of energy of any river depends upon two circumstances, its volume and its velocity.

5. That property should make it possible to build ballistic transistors, ultrahigh-frequency devices that would respond much more quickly than existing transistors.

6. It is not beyond the bounds of possibility that a stable solution of monatomic hydrogen may be produced, by the use of very low temperatures.

22. Прочитайте и переведите предложения, помня о том, что and, or или запятая часто стоят между несколькими определениями к одному существительному. В таких случаях при переводе целесообразно пользоваться «правилом ряда».

Например:

Мы применяем реакции кислорода, водорода и азота.

1. On the instrument board there are two sets of operational and navigational instruments.

2. We must include in our work the design and speed considerations.

3. Let’s scrutinize at all altimeter and compass readings.

4. During the 19th century the wave theory of light gained universal acceptance thanks to a remarkable series of developments on both the experimental and theoretical basis.

10. The scanning pattern¹⁶ at the transmitter, the exploring¹⁷ and reproducing elements and the communication channel connecting them are symbolically illustrated in the figure below.

11. Spaceships present an entirely new design and operational concept, unlike that in the common vehicle.

12. The fundamental difference between fusion and fission reactions is that it is extremely difficult to make light elements react.

The less stable a chemical compound, the greater is the chance of its being transformed into another or several other compounds.
