materjali (joon, pind või maht) mõõtmete muutumist iseloomustav tegur temperatuuriühiku kohta (vt joonpaisumistegur, mahtpaisumistegur)
Good to know
- Soojuspaisumistegurit käsitletakse sageli joopasumisteguri sünonüümina, kuigi eristatakse ka pind- ja mahtpaisumistegureid. (vt joonpaisumistegur, mahtpaisumistegur)

the fractional expansion of matter (ie the expansion of the unit length, area, or volume) per degree rise in temperature (see: coefficient of linear thermal expnsion, coefficient of volume thermal expension)
Good to know
- A coefficient of thermal expansion (CTE) typically refers to the linear coefficient of expansion. (see: coefficient of linear thermal expansion)

частичное расширение вещества (т. е. увеличение единичной длины, площади, или объёма) при увеличении температуры на один градус (см. коэффициент линейного теплового расширения, коэффициент объёмного теплового расширения)
Good to know
- Коэффициент термического расширения обычно относится к коэффициенту линейного теплового расширения (см. коэффициент линейного теплового расширения).

soojuspaisumistegur preferred

Usage examples

Soojuspaisumistegur iseloomustab objekti kalduvust muuta oma kuju, ruumala ja mahtu vastuseks temperatuuri muutusele.

ruumpaisumistegur

Usage examples

Ruumpaisumistegur näitab seda, et materjali ruumala muutub mõne fikseeritud murdosa võrra, nii nt võib terasplokk ruumalaga 1 kuupmeeter laieneda 1,002 kuupmeetrini, kui temperatuuri tõstetakse 50 K võrra.

symbol

coefficient of thermal expansion preferred

Usage examples

Coefficient of thermal expansion that the volume of a material changes by some fixed fractional amount. For example, a steel block with a volume of 1 cubic meter might expand to 1,002 cubic meters when the temperature is raised by 50 K.

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

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).
