Datum, немецкий
Datum, английский
- Начало [нуль] отсчета
- Исходное значение; начало отсчета; начальный уровень
- A position or element in relation to which others are determined.
- Данная величина; базовая линия
- A level surface or point to which other levels are related; a reference in measuring elevations.
- Точка отсчета
- The base level.
- (1) a material unit representing information about a portion of the real world that can be processed by explicit procedures and maintains its characteristics during repeated use. (2) a fact or figure transcribed in a readable language and on a durable medium (->channel). e.g., a completed questionaire, a taped interview, the recorded results of an experiment. events that leave no physical marks cannot be traced through data and physical marks that can no longer be interpreted, e.g., because the code linking them to particular observations is unavailable, loose the status of data. a datum rarely stands alone, hence the common use of its plural data. science typically processes large collections of data. in statistics each datum of a collection must contain the same kind of information.

Datum line, английский
- A line at the midpoint between the top and bottom of a lens, also referred to as the 180? line. unless otherwise specified, optical centers are ground on this line. “dbc” – distance between centers. “dbl” - distance between lenses – the closest distance between lenses. the figure is needed to compute decentration and is measured from the closest nasal point of one lens to the closest nasal point of the other lens. this measurement may be different that the marked bridge number on the frame.
