Decay, английский
- The decomposition of wood by fungi.
- Also known as radioactive decay . radioactive substances undergo radioactive decay, the rate of which is determined by the properties of the radionuclide. as decay proceeds the resulting activity of the parent nuclide reduces and will eventually disappear
- The decomposition of wood substance by fungi.
- 1. the process by which tissues become rotten, caused by the action of microorganisms and oxygen 2. damage caused to tissue or a tooth by the action of microorganisms, especially bacteria verb (of tissue) to rot the surgeon removed decayed matter from the wound.

- Гниение
- Разложение. в химии атмосферы—исчезновение загрязняющего вещества из воздуха в результате абсорбции или химической реакции на поверхности земли, удаления с дождем или превращения в какое-либо другое вещество.
- The segment of the envelope of a note in which the envelope goes from maximum to some mid-range level. also, the decline in level of reverberation over time.
Decay (burnout) stage of a fire, английский
The fire consumes available fuel, temperatures decrease, fire gets less intense (nfpa 921).
Decay (mt), английский
The falling off to zero of the current in an electrical circuit. magnetic fields can also decay in a similar manner. this is important in demagnetization.
Decay (rt), английский
Spontaneous change of a nucleus with emission of a particle or a photon. for a definite quality of a nuclide, the rate of decay is usually expressed in terms of half-life. decay curve (rt)
Decay chain, английский

Decay coefficient, английский
Коэффициент затухания
Decay constant, английский
- The decay constant represents the probability of a decay of a radioactive material per unit time.
- Коэффициент затухания; постоянная затухания; постоянная времени затухания
Decay cooling, английский
Охлаждение отработавших твэл (хранение отработавших твэл до момента, пока произойдет распад коротко- живущих изотопов
Decay curve, английский
- Graph showing radioactive intensity as a function of time for an isotope. decay curves are used in determining exposure times in radiologic testing. decibel (db): logarithmic unit for expressing relative signal power, such as the loudness of a sound, in proportion to the intensity of a reference signal. one tenth of a bel. decibel in signal amplitude is twice that in signal power. one decibel equals ten times the base ten logarithm of the ratio of two powers.
- График, показывающий интенсивность радиоактивности изотопа как функцию времени. кривые затухания используются для определения времени воздействия при радиологических испытаниях. децибел (дб): логарифмическая единица выражения относительной мощности сигнала, например громкости звука, пропорционально интенсивности опорного сигнала. одна десятая часть бел. амплитуда сигнала в децибелах вдвое превышает мощность сигнала. один децибел равен десятикратному логарифму по основанию десяти отношения двух степеней.
- In radiographic testing, graph showing activity as a function of time for an isotope. decay curves are used in determining exposure times. decibel (db): logarithmic unit for expressing relative acoustic signal power, such as the loudness of a sound, in proportion to the intensity of a reference signal. decibel in signal amplitude is twice that in signal power. twenty decibels is commensurate with ten-fold voltage amplification.

Decay time, английский
- Время распада (время выдерживания радиоактивных отходов с целью снижения их радиоактивности перед подачей на переработку)
- Время спада импульса
- Also known as `reverberation time` or `rt`, the time it takes for reverberation to decay to 60db below the original sustained level.

Knot, английский
- 1 knot = 1 nautical mile/h = 1.852 kilometres/h = 0.515 meters/sec
- A unit of speed, one nautical mile per hour or approximately 1.15 statute miles per hour. the nautical mile is closely related to the geographical mile which is defined as the length of one minute of arc on the earth's equator. by international agreement,
- That portion of a branch or limb that has been surrounded by subsequent growth of the stem. the shape of the knot as it appears on a cut surface depends on the angle of the cut relative to the long axis of the knot.
- In lumber, the portion of a branch or limb of a tree that appears on the edge or face of the piece.
- Узел
- A measurement of speed equal to one nautical mile (6,076 feet) per hour
- A unit of speed: 1 nautical mile (1.8520 km; 1.1508 mi) per hour. originally speed was measured by paying out a line from the stern of a moving boat; the line had a knot every 47 feet 3 inches (14.40 m), and the number of knots passed out in 30 seconds gave the speed through the water in nautical miles per hour. sometimes "knots" is mistakenly stated as "knots per hour," but the latter is a measure of acceleration (i.e., "nautical miles per hour per hour") rather than of speed.
- Unit of speed in navigation which is the rate of nautical mile (6,080 feet or 1,852 meters) per hour.
- Unit of speed in navigation which is the rate of nautical mile (6,080 feet or 1,852 meters) per hour. top of page home l

- Узел - морская единица измерения скорости, равная одной морской миле в час

- A large knob formed on the extremity of a rope, generally by untwisting its ends, and interweaving them regularly among each other; of these there are several sorts, differing in form, size, and name, as diamond knot, kop knot, overhand knot, reef knot, shroud knot, stopper knot, single wall knot, double wall knot. the bowline knot is so firmly made, and fastened to the cringles of the sails, that they must break, or the sails split, before it will slip. (see running bowline.) the sheepshank knot serves to shorten a rope without cutting it, and may be presently loosened. the wall-knot is so made with the lays of a rope that it cannot slip, and serves for sheets, tacks, and stoppers. knots are generally used to act as a button, in preventing the end of a rope from slipping through the hole of a dead-eye, or through the turns of a laniard, by which they are sometimes made fast to other ropes.— knot also implies a division on the log line, bearing a similar proportion to a mile, which half a minute does to an hour; that is, it is 1/120 of a mile; hence we say, the ship was going 8 knots, signifying 8 miles per hour. indeed, in nautical parlance, the words knot and mile are synonyms, alluding to the geographical mile of 60` to a degree of latitude.
- [1] any of countless ways of interlacing, twining, or looping cord, rope, or line, for fastening, binding, or connecting them together or to something else. [2] a speed equal to one nautical mile per hour (1.1516 mph; 1.853 km/h). landlubbers frequently refer to “a rate of knots” or speak of “knots per hour,” both of which are considered needless repetition (but see counter-argument below).
- A type of inclusion in which one diamond crystal is lodged inside a larger diamond crystal.
- Included diamond crystal oriented differently from the larger diamond crystal which is its host. when such diamonds are sawn, the knot may cause problems and slow the sawing process because it often presents a harder cutting direction.
- A maritime unit of speed equal to one nautical mile per hour (6076 feet).
- Aterm for hitches and bends.
- One nautical mile per hour.
- (1) a speed of one nautical mile per hour. (2) a method of attaching a rope or line to itself, another line or a fitting.
- A nautical unit of speed. one knot equals 1 nautical mile per hour (approximately 51 centimeters per second).
- Nautical miles per hour equal to 1.15 miles per hour (mph).
- A hard cross grained piece in a board generally from a branch protrusion; may loosen over time and fall out of the board.
