interphase, n. and a.|ˈɪntəfeɪz|
[f. inter- + phase.]
A. n. [inter- 2 b.]
1. Cytology. [a. G. interphase (H. Lundegårdh 1912, in Arch. f. mikrosk. Anat. LXXX. 27).] A stage in the cycle of nuclear division which intervenes between one mitosis and the next; also, a stage between the first and second division of meiosis. Also attrib. or as adj.
1913La Cellule XXIX. 308 For the excellent term ‘interphase’ we are indebted to Lundegårdh. 1932C. D. Darlington Recent Adv. Cytol. iv. 90 The chromosomes may form two daughter-nuclei at the poles and pass into a resting stage, the interphase. 1961Lancet 26 Aug. 488/1 Any X chromosomes in excess may produce a sex-chromatin body in the interphase nucleus. 1968M. W. Strickberger Genetics ii. 13 As compared to the period of active mitosis..the interphase or ‘intermitotic’ period of most cells is usually many times longer. Ibid. 21 The chromosomes pass into a short interphase before the second meiotic division begins.
2. Physical Chem. The region between two phases in which the properties are significantly different from the bulk properties of either phase.
1933Phil. Mag. XVI. 849 In recent years attention has been concentrated once more on the electro-chemistry of the interphase between mercury and an aqueous solution containing electrolytes. Ibid. 864 The surface tension of a liquid–liquid interphase is defined in such a way as to be applicable to any desired boundary in an interphase of finite thickness. 1955E. J. Pryor Introd. Mineral Dressing xvii. 428 In the solid-fluid interphase, forces of each phase meet and merge through a transition stage. 1970Bockris & Reddy Mod Electrochem. I. i. 2 An interface formed by two phases..is an apparent surface because..there is a region in which there is a continuous transition from the properties of one phase to the properties of the other. If one aims to refer specifically to this three-dimensional transition region, then it is more appropriate to use the term interphase. 1972Bockris & Dražić Electro-Chem. Sci. ii. 22 An interphase is a less sharply definable region, which will range over at least two molecular diameters, but may extend over thousands of ångströms.
B. adj. [inter- 5.]
1. Occurring or existing between two phases or states of matter.
1933Jrnl. Chem. Physics I. 8/1 The equilization [sic] of spreading force f in different phases within one field may take place in 3 ways: (a) Interphase mobility by which adatoms cross the phase boundary [etc.]. 1959Times 22 Jan. 2/5 (Advt.), The work will include calculation of interphase reactions in which water or steam is normally one phase. 1967B. P. Nicolsky et al. in G. Eisenman Glass Electrodes for Hydrogen vi. 175 We shall agree to regard the interphase potential as the electrical potential of the solid phase as compared with the liquid one.
2. Electr. Engin. Applied to an inductor used to connect two or more polyphase rectifiers so that they operate in parallel with the current divided between them.
1935Gen. Electric Rev. XXXVIII. 499/1 Polyphase rectifiers usually have an interphase transformer which serves to divide the anodes into two or more groups which operate in parallel. 1952Erikson & Bryant Electr. Engin. xxiv. 431 The presence of the interphase transformer is necessary to allow conduction in two tubes..at any given time. 1970J. Shepherd et al. Higher Electr. Engin. (ed. 2) xxv. 804 By the addition of an inter⁓phase reactor to the simple 6-phase connexion it is possible to obtain rectifier action with the smoothness of normal 6-phase rectification and the utilization factor of 3-phase rectification. |
