| dispersing electrode | In unipolar electrocardiography, a remote electrode placed either upon a single limb or connected with the central terminal and paired with an exploring electrode; the indifferent electrode is supposed to contribute little or nothing to the resulting record. Synonym: dispersing electrode, silent electrode. (05 Mar 2000) |
| dispersion | <microscopy> The variation of refractive index with colour (or wave-length) of light. The spreading of white light into its component colours when passing through a glass prism is due to dispersion which, in turn, is due to the fact that the refractive index of transparent substances is lower for long wavelengths than for-short wavelengths. A measure of dispersion is defined as: nD - 1 v= nF-nC where nD = refractlve index at 589 nm (yellow), nF = 486 nm (blue), nC = 656 nm (red). (05 Aug 1998) |
| dispersion colloid | A colloidal solution in which the dispersed phase can be concentrated by centrifugation. Synonym: dispersion colloid, molecular dispersed solution. (05 Mar 2000) |
| dispersion force | Forces of attraction between atoms or nonpolar molecules that result from the formation of induced dipoles. Sometimes referred to as London dispersion forces. Important in the DLVO theory of colloid flocculation and thus in theories of cell adhesion. (18 Nov 1997) |
| dispersion medium | The medium or fluid in which a disperse is suspended. Synonym: continuous phase, dispersion medium, dispersion phase, external medium. (05 Mar 2000) |
| dispersion phase | The medium or fluid in which a disperse is suspended. Synonym: continuous phase, dispersion medium, dispersion phase, external medium. (05 Mar 2000) |
| dispersion relation | <radiobiology> For a given wave, the dispersion relation relates the temporal frequency of a wave (w, or omega) to its wavenumber k and other physical quantities characteristic of the system. Dispersion relations can be quite simple (for example, w = k c for light, c being the speed of light), and they can also be quite complex, with interesting mathematical structure. The dispersion relation and its mathematical structure provide important information about the wave, including the phase and group velocities. Note that the meaning of dispersion relation is different in plasma physics than in other fields. (09 Oct 1997) |
| dispersion staining | <microscopy> A procedure involving central or annular stops in the objective back focal plane to induce coloured images of transparent particles mounted in liquids with indices matching the particle at a wavelength in the visible. The particle and liquid should possess very different dispersion curves for best colours. (05 Aug 1998) |
| dispersity | The extent to which the dimensions of particles have been reduced in colloid formation. (05 Mar 2000) |
| dispersive | Tending to disperse. <optics> Dispersive power, the relative effect of a material in separating the different rays of light by refraction, as when the substance is formed into a prism. Dispers"iveness. Source: Websters Dictionary (01 Mar 1998) |
| dispersoid | A colloidal solution in which the dispersed phase can be concentrated by centrifugation. Synonym: dispersion colloid, molecular dispersed solution. (05 Mar 2000) |
| dispireme | The double chromatin skein in the telophase of mitosis. Origin: G. Di-, twice, + speirema, coil, convolution (05 Mar 2000) |
| dispirit | 1. To deprive of cheerful spirits; to depress the spirits of; to dishearten; to discourage. "Not dispirited with my afflictions." (Dryden) "He has dispirited himself by a debauch." (Collier) 2. To distill or infuse the spirit of. "This makes a man master of his learning, and dispirits the book into the scholar." (Fuller) Synonym: To dishearten, discourage, deject, damp, depress, cast down, intimidate, daunt, cow. Origin: Pref. Dis- + spirit. Source: Websters Dictionary (01 Mar 1998) |
| dispirited | Depressed in spirits; disheartened; daunted. Dispir"itedly, Dispir"ited. Source: Websters Dictionary (01 Mar 1998) |
