| dynamic disease | A physical disorder with no known or detectable organic basis to explain the symptoms. See: behaviour disorder, neurosis. Synonym: dynamic disease, functional disease, functional illness. (05 Mar 2000) |
| dynamic equilibrium | Balance A condition in which no further net change is occuring in a system, and free energy is minimimal. (09 Oct 1997) |
| dynamic focusing | <microscopy> An automatic focusing adjustment of the electron beam in high-quality cathode-ray or video image pickup tubes. The beam is made to land with the properly shaped minimum-sized spot regardless of its position in the raster scan (05 Aug 1998) |
| dynamic force | <radiobiology> Typically defined as the ability to do work. Power is the rate at which work is done, or the rate at which energy is changed. Work characterises the degree to which the properties of a substance are transformed. Energy exists in many forms, which can be converted from one to another in various ways. Examples include: gravitational energy, electrical energy, magnetic and electric field energy, atomic binding energy (a form of electrical energy really), nuclear binding energy, chemical energy (another form of electrical energy), in addition to these forms of potential energy there are also kinetic energy (energy due to motion), and thermal energy (heat, a form of kinetic energy where the motion is due to thermal vibrations/motions), and so on.

| dynamic friction | The force that must be overcome to maintain steady motion of one body relative to another because they remain in contact. Compare: starting friction. (05 Mar 2000) |
| dynamic ileus | Intestinal obstruction due to spastic contraction of a segment of the bowel. Synonym: spastic ileus. (05 Mar 2000) |
| dynamic murmur | A heart murmur due to anaemia or to any cause other than a valvular lesion. (05 Mar 2000) |
| dynamic platform posturography | A force platform that evaluates somatosensory and visual influences on posture and equilibrium. Synonym: dynamic platform posturography. Origin: posture + G. Grapho, to write (05 Mar 2000) |
| dynamic psychiatry | Psychiatric theory and practice emphasizing the principles of psychoanalysis. Synonym: analytic psychiatry, dynamic psychiatry. (05 Mar 2000) |

| dynamic range | <microscopy> In video and other electronic equipment and in photographic emulsions, the ratio of the maximum to minimum signal levels that introduce no more than acceptable levels of signal amplitude distortions. (05 Aug 1998) |
