- Ratio of the weight of a volume of material to the weight of an equal volume of water at a given temperature (7).
- The ratio of the density of wood to the density of water at 4 c. specific gravity of wood is usually based on green
- The density (mass per unit volume) of any material divided by that of water at a standard temperature.
- The ratio of the weight of a given volume of material to the weight of an equal volume of water.
- Плотность
- Удельный вес
- A measure of how tightly packed the atoms of a substance are. varies by the mineral or substance. example, gold has a high specific gravity, while quartz has a low specific gravity. see also "density."
- As applied to wood, the ratio of the ovendry
- This measurement of weight is expressed in grams per cubic centimeter. a lower specific gravity means a lighter weight lens.
- Same as relative density
- The comparative weights of equal bulks of different bodies, water being generally represented as unity.
- In liquids such as drill mud, or solids such as diamond, the weight of a given volume as compared with an equal volume of pure water at 4° c.
- The ratio of a material’s density to that of water [ material weight in air ? (weight in air - weight in water)]. used to differentiate different kinds of volcaniclastics and other materials. sw
- The ratio of the weight of the solution to the weight of an equal volume of water at a specified temperature. used as an indicator of battery state-of-charge.
- Ratio of the mass of a material to the mass of an equal volume of water at 4°c. the range for modern fibers is not too great and is dependent to some extent on the liquid used as an immersant in measurements, because of fiber swelling and of possible absorption of liquid into fiber voids. (also see density.)
- The ratio of the density of a substance to the density of water. the specific gravity of water is at standard condition temperature and pressure.
- Term used in connection with testing a battery`s electrolyte. a specific gravity test is used to determine the battery`s state of charge. sealed “maintenance free” batteries sometimes have an indicator on top that indicates the state of charge.
- The density of a substance divided by the density of water. water has a density of 1 gram/cm3. the closer a lubricant’s specific gravity is to 1, the greater its tendency to absorb moisture and have poor demulsibility.
- The ratio of the density of a substance to the density of water, often at a specified temperature.
- Unitless ratio of the density of a material divided by the density of water. water has a density of about 1 g·cm–3, or 1000 kg·m–3.
- Unitless ratio of the density of a material divided by the density of water. water has a density of about 1 g/cm3, or 1000 kg/m3, at 15.6 °c (60 °f).

Удельный вес, русский
- , вес единицы объема вещества. в отличие от плотности, удельный вес не является физико-химической характеристикой вещества, т. к. зависит от места измерения.
- См. плотность

- Ускорение свободного падения, ускорение силы тяжести ~ of hardening by heat ускорение твердения (смесей) тепловой обработкой [нагревом] ~ of set(ting) ускорение схватывания ~ of translation ускорение поступательного движения
- Developed by the american petroleum institute, this standard measures the density of liquid as expressed by degrees. the lower the degree, the heavier the liquid.
- The attraction exerted by the earth`s mass on objects at its surface.

Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.
- Температура
- Температура тмр test methods and procedures методы проведения испытаний и последовательность их проведения тмр theodolite measuring point кинотеодолитная станция
- Temperatura, fiebre
- The condition attained when the wetted wick of a wet-bulb thermometer has reached a stable and constant temperature when exposed to moving air in excess of 900 ft (274.3 m) per minute.
- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).
- Повышение температуры бетона ~ of truss высота фермы jet ~ высота подъёма горизонтальной неизотермической приточной струи, «всплывающей» над приточным отверстием

- Normal adult temperature varies among horses, but will usually range in degrees from 99.5°f to 100.5°f.
- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
- Measure of the intensity of particle motion in degrees celsius (°c), degrees fahrenheit (°f) or, in the absolute scale, kelvin (k) or degrees rankine (°r). an increment of 1 k = 1 °c = 1.8 °r = 1.8 °f. compare heat.
