temperature damâ (#) Fr.: température A physical quantity characterizing the mean random motion of molecules in a physical body. In other words, a measure of the average kinetic energy of the particles of a system. From L. temperatura "a tempering, moderation," from temperatus, p.p. of temperare "to moderate, to mix." Sense of "degree of heat or cold" first recorded 1670 (Boyle), from L. temperatura, used in this sense by Galileo. Damâ, from dam "breath of an owen; bellows; smoke; air," also "moment, time," from Mid./Mod.Pers. damidan "to blow, breathe;" Av. dāδmainya- "blowing up;" cf. Skt. dahm- "to blow," dhámati "blows;" Gk. themeros "austere, dark-looking;" Lith. dumti "to blow;" PIE dhem-/dhemə- "to smoke, to blow." |

tempon tempon Fr.: tempon An elementary unit of time defined as the duration which is necessary for light to travel a distance equal to the classical radius of an electron. Thus, one tempon (τ) is equal to (e^{2}/mc^{2})(1/c)≅ 10^{-23} seconds. From tamp, from L. tempus "time" + → -on. |

temporal resolution vâgošud-e zamâni Fr.: résolution temporelle The measure of the ability of an observing system to clearly separate events in time. In other words, the shortest time interval that can be determined between two different events. → temporal hour; → resolution. |
temporality tâmenigi Fr.: temporalité Temporal character or nature. |
temporary tâmenvâr Fr.: temporaire Lasting, existing, serving, or effective for a time only; not permanent. From L. temporarius "according to circumstances, of seasonal character, lasting a short time," from tempus (genitive temporis) "time, season." Tâmenvâr, from tâmen "time", → temporal, + -vâr suffix denoting suiting, befitting, resembling, in the manner of. |
temporize tâmenidan Fr.: temporiser To be indecisive or evasive to gain time or delay acting (Dictionary.com). From M.Fr. temporiser "to pass one's time, wait one's time," from M.L. temporizare "to pass time," from L. tempus (genitive temporis), → temporal. |
ten dah (#) Fr.: dix A cardinal number, nine plus one. M.E. ten(e), tenn(e), O.E. ten(e), tien(e); from P.Gmc. *tekhan (cf. O.S. tehan, O.N. tiu, Dan. ti, Du. tien, O.H.G. zehan, Ger. zehn "ten"), cognate with Pers. dah, as below. Dah, from Mid.Pers. dah "ten;" Av. dasa "ten;" cf. Skt. dáśa- "ten;" Gk. deka "ten;" L. decem "ten;" O.Ir. deich; Lith. dešimtis "ten;" PIE base *dekm. |
tense tanu Fr.: tendu Stretched tight, as a cord, fiber, etc.; drawn taut; rigid. From L. tensus, p.p. of tendere "to stretch," → tension. Tanu "stretched, strained," from tan + -u suffix of excess. The first element tan, from tanidan "to spin, twist, weave" (Mid.Pers. tanitan; Av. tan- to stretch, extend;" cf. Skt. tan- to spin, stretch;" tanoti "stretches," tantram "loom;" Gk. teinein "to stretch, pull tight;" L. tendere "to stretch; PIE base *ten- "to stretch"), Pers. târ "string," tân "thread," tur "fishing net, net, snare," and tâl "thread" (Borujerdi dialect) belong to this family; variants tanta "cobweb," tanadu, tafen, kartané, kârtané, kâtené, Pashtu tanistah "cobweb;" cf. Skt. tantu- "cobweb, thread, string"). |
tensile taneši (#) Fr.: extensible Of or pertaining to → tension. From M.L. tensilis "capable of being stretched," from L. tensus, p.p. of tendere "to stretch," → tension. Taneši, related to taneš, → tension. |
tensile force niruy-e taneši Fr.: force de traction The force tending to stretch (or produce tension in) an object |
tension taneš (#) Fr.: tension General: The act of stretching or straining; the state of being
stretched or strained. M.E., from M.Fr. tension, from L. tensionem (nominative tensio) "a stretching," from tensus, p.p. of tendere "to stretch," cognate with Pers. taneš, as below. Taneš, verbal noun from tanidan "to spin, twist, weave;" Mid.Pers. tanitan; Av. tan- to stretch, extend;" cf. Skt. tan- to spin, stretch;" tanoti "stretches," tantram "loom;" Gk. teinein "to stretch, pull tight;" L. tendere "to stretch; PIE base *ten- "to stretch"), Pers. târ "string," tân "thread," tur "fishing net, net, snare," and tâl "thread" (Borujerdi dialect) belong to this family; variants tanta "cobweb," tanadu, tafen, kartané, kârtané, kâtené, Pashtu tanistah "cobweb;" cf.

tensor tânsor, tângar Fr.: tenseur A system of numbers or functions where components obey a certain law of
transformation when the variables undergo a linear transformation.
A tensor may consist of a single number, in which case it is
referred to as a tensor of order zero, or simply a → scalar.
The tensor of order one represents a → vector.
Similarly there will be tensors of order two, three, and so on. Agent noun of tense (v.) → tension. |

tensor density cagâli-ye tânsor Fr.: densité de tenseur A generalization of the tensor concept that like a tensor transforms, except for the appearance of an extra factor, which is the → Jacobian matrix of the transformation of the coordinates, raised to some power, in transformation law. The exponent, which is a positive or negative integer, is called the weight of the tensor density. → weight of a tensor density. Ordinary tensors are tensor densities of weight 0. Tensor density is also called → relative tensor. |
