profiilielementide kõrguste standardhälve
Usage examples
  • Pinna metroloogias on profiilielementide kõrguste standardhälve standarditud parameeter, mis on ISO 21920-2 spetsifikatsiooni kohaselt määratletud tähistega Pcq või Wcq või Rcq. See parameeter esindab järjestikuste profiilielementide üksikute kõrguste ruutkeskmist hälvet, kus iga element koosneb ühest tipust ja ühest külgnevast orust.

Usage examples
  • In surface metrology, the standard deviation of profile element heights is a standardized parameter defined as Pcq or Wcq or Rcq under the ISO 21920-2 specification. It represents the root-mean-square deviation of the individual heights of sequential profile elements (where each element consists of one peak and one adjacent valley).
