Переведите следующие предложения, обращая внимание на при­частные обороты:

21. The work of L. de Broglie soon followed by the
"wave-mechanics" of Schrödinger was of great importance.

22. The angle of incidence of the electron beam on the
crystal being fixed, the accelerating potential was varied
gradually.

23. As stated before, the greater the binding energy, the
more stable the nucleus.

24. Only the uranium series is shown, it being typical of
the rest.

25. Any body persists in its slate of rest or uniform
motion in a straight line, unless acted on by some force.

26. Carbon disulphide (CS2) burns readily, its vapour
burning explosively when mixed with air.

27. With further heating the waves are still shorter and
colour advances along the spectrum, with yellow, then blue
waves, being emitted.

28. As expected, using the cross section defined by equation
6, one obtains results differing radically from those already
considered.

29. There being a close packing of molecules in a liquid,

the molecular encounters occur much more frequently than in a gas under the same conditions.

30. It is a common observation that bodies expand when

heated.

31. It is a matter of common observation thet light is
refracted when passing from one medium into another.

32. The basic principle is shown in Figure 6, which-
represents a filament inside a metal cylinder, the combination
enclosed in a glass bulb.

33. In the radioactive bodies alpha-, beta- and gamma-rays
are emitted spontaneously, and at a rate uninfluenced by any
chemical agency.

34. According to atomic theory, well fortified as it is by
the analysis of spectra, every kind of atom but one and every
kind of molecule without exception is equipped with more
than one electron.

tube is an annular lip.

36. The part played by the electron is that of the elementary
corpuscle of negative electricity.

37. Diffusion of gases or liquids through porous
membranes results in separation, the lighter isotopes diffusing

more rapidly.

38. The first step towards intimate understanding of a
chemical reaction is to determine the formulae of the
compounds involved.

39. The remaining light, coming as it does from the edge
of the sun, is much altered in quality, so that both sky and
landscape take on a strange colour.

40. From the northern station Venus is seen projected
upon the Sun's surface.

41. There exist, of course, various kinds of light, each
corresponding to some definite "colour".

42. Chadwick announced the discovery of the neutron, a

particle having a mass nearly the same as that of a proton but carrying no charge.

43. Involved in the star fields of the individual galaxies,
especially those of spiral and irregular form, are both bright
and dark nebulae, and groups of stars in all degrees of
organization.

44. Let о be the diameter of a molecule, and imagine a
sphere of radius a drawn round each molecule and concentric
with it.

45. Passing from one chemical element to the next, one
would find the nuclear charge increasing by one, the number
of electrons revolving also growing by one.

ions is a strong absorption coefficient in the infrared.

47. Going around the Earth once every 29 days is our
Moon, at a distance of 24 000 miles.

48. Coming as it did so early in the history of kinetic
theory, Meyer and Ferri's experimental result published in
1835, was of great importance in helping to establish the
validity of the new interpretation.

49. Concealed in the foregoing figures are some very
important facts, which I shall point out.

50. These compounds may be prepared by similar
methods, namely, by the action of the corresponding acids
upon the hydroxides or carbonates, by the action of the
elements on solutions of hydroxide followed by evaporation
to dryness and subsequent ignition to decompose the oxysalts.

51. Radioactivity was discovered by Henri Becquerel in
February 1896, following the published announcement just
a month earlier of the discovery of X-rays by Roentgen.

rapid succession, provide a simple interpretation of the
production of showers.

54. The theory of this action is too extensive a subject
to be developed in the present work, belonging as it does
