density denseness | the amount per unit size |
vapor density vapour density | the density of a gas relative to the density of hydrogen |
concentration density denseness tightness compactness | the spatial property of being crowded together |
flux density flux | (physics) the number of changes in energy flow across a given surface per unit area |
optical density transmission density photographic density absorbance | (physics) a measure of the extent to which a substance transmits light or other electromagnetic radiation |
rarity tenuity low density | a rarified quality, the tenuity of the upper atmosphere |
relative density | the ratio of the density of something to the density of a standard |
magnetic field strength magnetic intensity magnetic induction magnetic flux density | the amount of magnetic flux in a unit area perpendicular to the direction of magnetic flow |
flux density unit | a measure of the amount of flux per unit of cross sectional area |
proportion ratio | the relation between things (or parts of things) with respect to their comparative quantity, magnitude, or degree, an inordinate proportion of the book is given over to quotations, a dry martini has a large proportion of gin |
case-to-infection proportion case-to-infection ratio | the number of cases of a disease divided by the number of infections with the agent that causes the disease |
ratio | the relative magnitudes of two quantities (usually expressed as a quotient) |
aspect ratio | the ratio of the width to the height of a tv picture |
focal ratio f number stop number speed | the ratio of the focal length to the diameter of a (camera) lens system |
loss ratio | the ratio of the annual claims paid by an insurance company to the premiums received |
output-to-input ratio | the output power of a transducer divided by the input power |
price-to-earnings ratio P E ratio | (stock market) the price of a stock divided by its earnings |
signal-to-noise ratio signal-to-noise signal noise ratio signal noise S N | the ratio of signal intensity to noise intensity |
high-density lipoprotein HDL alpha-lipoprotein | a lipoprotein that transports cholesterol in the blood, composed of a high proportion of protein and relatively little cholesterol, high levels are thought to be associated with decreased risk of coronary heart disease and atherosclerosis |
low-density lipoprotein LDL beta-lipoprotein | a lipoprotein that transports cholesterol in the blood, composed of moderate amount of protein and a large amount of cholesterol, high levels are thought to be associated with increased risk of coronary heart disease and atherosclerosis |
very low density lipoprotein VLDL | large lipoproteins rich in triglycerides, VLDLs circulate through the blood giving up their triglycerides to fat and muscle tissue until the VLDL remnants are modified and converted into LDL |
low-density(a) | having low concentration, low-density urban areas |
low-density(p) | having low relative density or specific gravity |
