Diamond, английский
- Брильянт - конфигурация головы и плеч, в которой воротник “разорван”, поэтому конфигурация имеет ромбовидный вид;
- Mineral composed essentially of carbon crystallized at extremely high temperatures and pressures; in nature, diamonds form 150 to 200km (93 to 124 miles) or more below the earth`s surface. diamond is the hardest of all known natural substances (10 on the mohs scale); its refractive index is 2.417, dispersion 0.044, specific gravity 3.52, and its lustre is adamantine. diamond ranges from colourless to yellow, brown, gray, orange, green, blue, white, black, purple, pink and extremely rarely, red. transparent and near-colourless is a desirable colour, diamond is a highly valued gemstone.
- A diamond is a precious gem, comprised of a crystalline form of pure carbon, the hardest naturally occurring substance.
- The hardest known substance composed of carbon crystallized in the isometric system, the more common crystal forms being the octahedron and rhombic dodecahedron. the cube and some com¬plex and combination forms of the isometric system are found, as well as rounded, distorted, twinned, and cryptocrystalline forms. although very hard, diamond has excellent cleavage and breaks readily under a blow, yielding flat surfaces parallel to the octahedral planes. diamonds usually are classified as either "gems" or "industrials" on the basis of color, shape, size, crystal form, and the size and location of inclusions or other imperfections. dia¬monds sometimes also are classified on a geographical basis, such as angolas, brazilians, congos, sierra leones, or west africans. this does not strictly mean that diamonds so classed come from that specific geographical area but that they are similar to stones characteristically produced by mines in that locality. a method for synthesizing diamonds has been developed, and small industrial diamonds have been produced on a commercial scale. these synthetic diamonds are commonly called "manmade" and/or "mm diamonds."

Diamond bit, английский
- Any bit having diamonds inset in its crown, which serve as the cutting points or media. commonly also called boart bit, boart-set bit, bort bit, bort-set bit, bortz bit, bortz-set bit.
- A drill bit that has small industrial diamonds embedded in its cutting surface. cutting is performed by the rotation of the very hard diamonds over the rock surface.

Diamond cleavage, английский
The plane along which a diamond crystal can be split easily. the four planes parallel¬ing the faces of an octahedron are those generally referred to as the cleavage planes, or diamond cleav¬age. all crystalline diamonds are more or less brittle and will be fractured by a sufficiently violent blow, but the irregular surface of a fracture cannot be mistaken for the brilliant flat surface produced by cleaving. the carbon has no cleavage, and in ballas cleavage is absent or very poorly defined. diamond cleaving. the act or process of splitting dia¬monds into smaller pieces, which may be more readily used as tool points, gems, or drill diamonds. diamond concentration. the ratio of the area of a single-layer bit face covered by the inset diamonds or, in an impregnated bit, the bulk proportion of the crown occupied by diamonds.

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).
