| magnitude | 1. Extent of dimensions; size; applied to things that have length, breath, and thickness. "Conceive those particles of bodies to be so disposed amongst themselves, that the intervals of empty spaces between them may be equal in magnitude to them all." (Sir I. Newton) 2. <geometry> That which has one or more of the three dimensions, length, breadth, and thickness. 3. Anything of which greater or less can be predicated, as time, weight, force, and the like. 4. Greatness; grandeur. "With plain, heroic magnitude of mind." 5. Greatness, in reference to influence or effect; importance; as, an affair of magnitude. "The magnitude of his designs." (Bp. <optics> Horsley) Apparent magnitude, the angular breadth of an object viewed as measured by the angle which it subtends at the eye of the observer; called also apparent diameter. <astronomy> Magnitude of a star, the rank of a star with respect to brightness. About twenty very bright stars are said to be of first magnitude, the stars of the sixth magnitude being just visible to the naked eye. Telescopic stars are classified down to the twelfth magnitude or lower. The scale of the magnitudes is quite arbitrary, but by means of photometers, the classification has been made to tenths of a magnitude. Origin: L. Magnitudo, from magnus great. See Master, and cf. Maxim. Source: Websters Dictionary (01 Mar 1998) |

| peak magnitude | The greatest amplitude. (05 Mar 2000) |
| average | <statistics> A value that represents the sum of values divided by the number of values in the set. It represents or summarises the relevant features of a set of values. Origin: M.E. Averays, loss from damage to ship or cargo, fr. It. Avaris, fr. Ar. 'awariya, damaged goods, + damage (05 Mar 2000) |
| average flow rate | <physiology> The flow rate determined by dividing the total volume passed in a time period divided by the time period, usually quoted in mls per minute. (05 Mar 2000) |
| average megawatt | <physics> One megawatt of capacity produced continuously over a period of one year. 1 MWa = 1 MW x 8760 hours/year = 8,760 Mwh = 8,760,000 kWh. Acronym: MWa (05 Dec 1998) |
| law of average localization | Visceral pain is most accurately localised in the least mobile viscera and least accurately in the most mobile. (05 Mar 2000) |
| abdominal pulse | The soft, compressible aortic pulse occurring in certain abdominal disorders. Synonym: pulsus abdominalis. (05 Mar 2000) |
| alternating pulse | Mechanical alternation, a pulse regular in time but with alternate beats stronger and weaker, often detectable only with the sphygmomanometer and usually indicating serious myocardial disease. Synonym: pulsus alternans. (05 Mar 2000) |
| amplitude of pulse | See: average pulse magnitude, peak magnitude. (05 Mar 2000) |
| anacrotic pulse | A pulse wave showing one or more notches or indentations on its rising limb that are sometimes detectable by palpation. Synonym: pulsus anadicrotus. (05 Mar 2000) |
| asynchronous pulse generator | A generator in which the rate of discharge is independent of the natural activity of the heart. Synonym: fixed rate pulse generator. (05 Mar 2000) |
| atrial synchronous pulse generator | A ventricular stimulating pulse whose rate of discharge is directly determined by the atrial rate. Synonym: atrial triggered pulse generator. (05 Mar 2000) |
| atrial triggered pulse generator | A ventricular stimulating pulse whose rate of discharge is directly determined by the atrial rate. Synonym: atrial triggered pulse generator. (05 Mar 2000) |
| bigeminal pulse | A pulse in which the beats occur in pairs. Synonym: bigemina, coupled pulse, pulsus bigeminus. (05 Mar 2000) |
| bisferious pulse | An arterial pulse with peaks that may be palpable. Synonym: pulsus bisferiens. (05 Mar 2000) |
