CTE variant
  • pikkuse (pindala või mahu) muutus temperatuuri muutuse kohta antud konstantsel rõhul
  • suurus, mis iseloomustab keha joonmõõtme (pikkuse, laiuse või kõrguse) suurenemist soojenemisel
  • fractional change in length or area or volume per unit change in temperature at a given constant pressure
  • fractional expansion of matter (ie the expansion of the unit length, area or volume) per degree rise in the temperature
  • ratio of the fraction change of length to the change in temperature
joonpaisumistegur preferred
Usage examples
  • Soojuspaisumisest tingitud objekti pikkusmõõtme muutus on seotud temperatuuri muutusega joonpaisumisteguri abil ja selleks on pikkuse murdosa muutus temperatuuri muutuse kraadi kohta.
lineaarpaisumistegur
α symbol
Usage examples
  • Tähisele α lisatakse indeksid, mis tähistavad vastavalt mõõdetava osise joonpaisumistegurit αmo ja tööetaloni joonpaisumistegurit αet.
paisumistegur
soojuspaisumistegur variant
Good to know
  • Soojuspaisumine on aine kalduvus muuta oma kuju, pindala ja mahtu vastuseks temperatuuri muutumisele.
linear expansion coefficient preferred
Usage examples
  • To a first approximation, the change in length measurements of an object due to thermal expansion is related to temperature change by a coefficient of linear expansion, and it is the fractional change in length per degree of temperature change.
coefficient of linear expansion
α symbol
Usage examples
  • To the symbol are added subscripts to denote the coefficient of linear expansion for the workpiece (i.e. αw) and the working standard (i.e. αs).

thermal expansion coefficient variant
Good to know
  • Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature.
