单词 N
释义 N|ɛn|
the fourteenth letter of the modern, and thirteenth of the ancient Roman alphabet, represents historically the Greek and the Semitic nun. The earlier Greek forms were {egnu1} and {egnu2}, corresponding to the Phœnician 𐤍. The sound usually denoted by the letter is a voiced nasal consonant with front closure (the point of the tongue touching the teeth or the fore part of the palate). It is, however, also capable of being used as a sonant or vowel, here denoted by |(ə)n|, as in bidden |ˈbɪd(ə)n|, bitten |ˈbɪt(ə)n|, slacken |ˈslæk(ə)n|. With one or other of these values the letter is very frequent in English, and is silent only in a few cases at the end of syllables after l and m, as kiln, damn, condemn, contemn, limn, hymn, solemn, column.
Before the sounds |g| and |k| the letter n is also employed in English to denote a nasal with back tongue-closure, in this dictionary distinguished as |ŋ|, as in finger |ˈfɪŋgə(r)|, think |θɪŋk|. When not followed by these sounds, this back-nasal is expressed by the digraph ng, as in hang |hæŋ|, sing, song. (On the difference in pronunciation between finger and singer, etc., see the note to the letter G.)
In Scottish texts of the 15–16th centuries the change of Latin and French gn to ng is frequently represented in the spelling of such words as sing sign, ring, reng reign, and ngn is common between vowels, as resingnit resigned, mangnitude, etc.
2. In OE. n is very frequent as the terminal letter of inflectional syllables, as in the -an of the infinitive and the oblique cases of weak nouns. In southern texts this n is always retained, but in the north it appears to have been generally dropped by the middle of the 10th century. In ME. the retention or dropping of the letter varied in the different midland and southern dialects. On the other hand, the -en of strong past pples., which became in southern dialects, was retained in the north as in modern English.
In inflectional syllables (as in reading, writing, etc.) -ng has in many dialects been reduced to n, and this pronunciation (usually called ‘dropping one's g's’) may sometimes be heard even from educated speakers.
3. In ME. the n of the indefinite article an is frequently transferred to a following word beginning with a vowel (while a converse process has given such forms as adder, apron, and auger). The forms thus produced occasionally alliterate with words properly beginning with n, and in one or two cases (as newt and nickname) have finally established themselves in the language. The following are examples of the practice from ME. and early modern texts.

b. In Physics and Chem. n represents the principal quantum number of an electronic orbit in an atom, which determines the energy of the orbit (to the first order) and can take the values 1, 2, 3,{ddd}(corresponding to increasing energy). In molecular spectroscopy n was introduced to denote the vibrational quantum number of a diatomic molecule (now usu. replaced by v), and later (as N) the total angular momentum, apart from spin, of diatomic and polyatomic molecules (see also quot. 19621).
[1914N. Bohr in Phil. Mag. XXVII. 507 According to Balmer, Rydberg, and Ritz the frequency of the lines in the line-spectrum of an element can be expressed by the formula v = fr(n1) - fs(n2), where n1 and n2 are whole numbers and f1, f2,{ddd}a series of functions of n, which can be expressed by fr(n) = (K/n2r(n), where K is a universal constant and ϕ a function which for large values of n approaches the value unity.] Ibid. 508 We shall assume that this spectrum is emitted by a system possessing a series of stationary states in which, corresponding to the nth state, the energy, omitting the arbitrary constant, is given by λn = - hK/n2.Ibid. 509 For n = 1, corresponding to the normal state of the atom, we get [etc.].1920Sci. Abstr. A. XXIII. 423 If the nuclei are related in a quasi-elastic manner to the equilibrium positions, then the energy values for a diatomic non-rotating molecule are the same as for a Planck oscillator, namely: E = nhω, where n denotes the quantum number for the atomic oscillation.1922A. D. Udden tr. Bohr's Theory of Spectra iii. i. 67 This quantum number which will always be denoted by n will therefore be called the ‘principal quantum number’.1926E. C. Kemble et al. in Bull. Nat. Res. Council No. 57. 5 Some discrepancies in minor details of notation will be found from chapter to chapter in this report. The following major items, however, have been followed consistently:..Vibrational quantum number for diatomic molecule: n.1951D. Bohm Quantum Theory xv. 348 n = the principal quantum number..defined as one plus the total number of nodal surfaces in the wave function.1953Jrnl. Optical Soc. Amer. XLIII. 425/1 [Report of Sub-committee of the Joint Commission for Spectroscopy.] Notation for diatomic molecules... N. Total angular momentum of the electrons and nuclei, excluding spin... Replaces former K.1962P. J. & B. Durrant Introd. Adv. Inorg. Chem. vii. 207 The angular momentum due to the rotation of the [diatomic] molecule about an axis at right angles to the internuclear axis is denoted by N.1962J. Potter tr. Messiah's Quantum Mech. II. xxi. 964 Each quantum number n represents the number of vibrational quanta relative to a particular normal mode of vibration.1966G. Herzberg Molecular Spectra & Molecular Struct. III. i. 73 For 3σ states each rotational level except the one with N = 0 is split into three component levels..corresponding to J = N + 1, N, N - 1, respectively.1973J. Yarwood Atomic & Nuclear Physics vi. 188 The quantum mechanical treatment [of the one-electron atom] introduces the integral principal quantum number n which..decides the total energy of the system, the quantum number l which..has any integral value between o and (n - 1), and the azimuthal magnetic quantum number ml which is an integer having (2l + 1) values between + l and - l.
5. n-declension, the ‘weak’ declension of Teutonic nouns and adjectives, in which the stem ends in n; so n-stem, n-plural.
1843Proc. Philol. Soc. I. 73 The n declension..makes its appearance in many of the Indo-European languages, besides the Gothic.1866Morris Ayenb. Inwyt p. xxxv, They are remnants of the n declension.1886T. Le M. Douse Introd. Gothic p. x, Consonant Declensions; n-stems.1894V. Henry Comp. Gram. Engl. & Germ. 236 The n-plural requires no explanation.
6. N-rays (originally n-rays), a form of radiation app. identified in 1903 by R. Blondlot of the University of Nancy, from the initial letter of which the name is derived. N1-rays (originally n1-rays), another form of radiation, having, in some respects, the opposite effects. [Soon after their alleged discovery it was concluded that such rays do not exist and Blondlot's work was in error.]
1903Nature LXVIII. 119/2 The name n-rays is suggested for these radiations.Ibid. 578/1 Several papers on the so-called N rays discovered by M. Blondlot are printed in the Journal de Physique for August.1904― LXIX. 455/2 The n1-rays, described in the previous note, have exactly the opposite effect.1906Nature 1 Mar. 413/1 It would be interesting to know whether anyone has obtained success in repeating the latest experiment designed to show the objective reality of the n-rays.1925A. Huxley Let. 25 Jan. (1969) 241 You remember the unanimously favourable verdict in favour of N rays?1941W. Seabrook Doctor Wood: Mod. Wizard of Laboratory xvii. 234 According to Blondlot, the rays were given off spontaneously by many metals. A piece of paper, very feebly illuminated, could be used as a detector, for, wonder of wonders, when the N rays fell upon the eye they increased its ability to see objects in a nearly dark room.1973Nature 12 Oct. 344/2 The protracted error immortalised in scores of publications can be due only to psychological (self-deception), not to chemical causes. The ‘anomalous’ water belongs to the category exemplified by the N rays of Blondlot.
7. Radiology. A unit of neutron dosage (see quot. 1942). Obs.
1942Aebersold & Lawrence in Ann. Rev. Physiol. IV. 36 In this laboratory, a standard Victoreen r-meter with a 100r condenser-chamber is used. The unit of fast neutron exposure is arbitrarily taken as that amount which produces the same reading with this meter as a roentgen of x-ray. Thus an n of fast neutrons produces inside this 100r Victoreen thimble chamber the same amount of ionization as produced by an r of x-rays.1948E. Paterson in R. Paterson Treatment of Malignant Dis. by Radium & X-Rays xxxiii. 593 The n unit has fulfilled a useful function, however, in demonstrating differences in effect between X- or gamma-radiation and neutrons when ratios of the dosage required to produce effects are compared.
