oru ruutkeskmine hälve
Svq
dale root mean square deviation
Svq
  • tõenäosusparameeter, milleks on pinnatopograafia orgude ala kaudu teostatud lineaarse regressiooni kalle
  • probability parameter that is the slope of the linear regression performed through the dale region
  • deviation parameter that is the slope of a linear regression performed to the dale region
oru ruutkeskmine hälve
Usage examples
  • Oru ruutkeskmine hälve, tähistatuna 3D-s Svk või 2D-s Pvq ja Rvq, võimaldab mõõta ja hinnata pinnaprofiili ruutkeskmist hälvet orgudes või lohkudes, mis asuvad südamiku/põhi pinnamaterjali all.
  • Oru ruutkeskmist hälvet saab tõlgendada kui pinna oru komponendi genereerinud juhusliku protsessi Sq-väärtust mikromeetrites.

dale root mean square deviation
Usage examples
  • Dale root mean square deviation (referred to as Svk in 3D or Pvq and Rvq in 2D) measures the root mean square deviation of the surface profile within the "dales" - the valleys or depressions located below the core surface material.
  • The dale root mean square deviation can thus be interpreted as the Sq-value, in micrometrs, of the random process that generated the dale component of the surface.
