英语词汇“secondary extinction”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

(c) A reduction in the intensity of X-rays diffracted by a crystal owing to interference between the incident beam and beams multiply diffracted by the lattice planes ( primary extinction) and to the progressive weakening of the incident beam in its passage through the crystal as energy is diverted into the diffracted beams ( secondary extinction).

1914 C. G. Darwin in London, Edinb. & Dublin Philos. Mag. 6th Ser. 27 681 The extinction is complete long before the [X-]rays going in a slightly different direction are appreciably absorbed. This fact is important in explaining the reflexion from an ordinary imperfect crystal.

1922 C. G. Darwin in London, Edinb. & Dublin Philos. Mag. 6th Ser. 43 804 The extinction itself..exerts two effects, which may be called primary and secondary.

1934 W. P. Davey Study Crystal Struct. x. 308 The cleavage faces of all actual single crystals are perfect enough to show a little primary extinction and are imperfect enough to show a great deal of secondary extinction.

1948 K. Lonsdale Crystals & X-rays vi. 140 The effect of this primary extinction..is an enormous apparent increase in absorption, over a very restricted range of angle.

1966 D. G. Brandon Mod. Techniques Metallogr. 83 Crystal imperfections will prevent double diffraction and hence prevent extinction, leading to an increased diffracted intensity in regions of lattice strain.
