- Насыщение-отбора проб. обычно, особенно в сша, так называется прибор, в котором имеются таймер (регулятор выдержки времени), коллектор и 6 или более клапанов с проходным отверстием для подачи воздуха в различные устройства для забора проб через заданные интервалы времени. этот термин относится также к автоматическому устройству для ежечасных: замеров концентрации дыма. воздух пропускается при постоянной скорости через бумажный фильтр, на котором после этого остается темное пятно дымовых частиц. фильтровальная бумага (в виде свернутой в трубочку полоски шириной: 20—30 мм) проходит через зажим фильтра, закрепленный пружинами для обеспечения герметичности. в конце каждого-часа зажим открывается и полоска бумаги продвигается вперед на 40—50 мм, после чего зажим опять защелкивается. в результате на бумаге образуется ряд пятен, каждый час-по одному пятну. термин «последовательный пробоотборник» иногда применяется также для обозначения полуавтоматического прибора (см. semi-automatic apparatus).
- Overload of a magnetic tape. the saturation point is the point at which an increase in magnetizing force does not cause a corresponding increase in magnetization of the tape oxide particles.
- In color management, the purity of a color’s hue, moving from gray to the pure color. save (v)
- 1. the maximum intensity or purity of a color. if the color is as brilliant as possible, it is at saturation; if the color is subdued or grayed, it is dull, weak, and low in intensity. 2. the upper limit concentration of a solute in a solvent, i.e., no more solute can be dissolved at a fixed temperature and pressure.
- The intensity or purity of a hue; the color of the greatest purity are those in the spectrum. words used to describe saturation are vivid, dull, brilliant, dark, deep, light, medium, pale, and weak.
