Quid significat "UNC"?

UNC refert ad stamina crassa in Civitatibus Foederatis stamina IR seriei unita (stamina radicum radicum ad libitum externum).

Quid" curatio superficiei Oxide nigrae?

Oxide nigra, media communis curatio superficiei chemicae.Oxide nigra communis est methodus superficiei chemicae curationis.Principium est velum oxydatum producere in superficie metallica ad aerem segregandum et propositum rubiginis praeventionis consequi.Cum apparentia requisita non sunt alta, denigratio adhiberi potest, et superficies partium ferri denigrata est, quae etiam caerulea appellatur.

Communiter usi curationis oxydi nigri methodi alcalini calefactionem denigrationem traditionalem comprehendunt et locus temperatura denigratio quae postea accidit.Attamen processus nigricationis in cella temperie non valde efficax est ad chalybem demissam carbonis.Alkalina denigratio subdividitur, et differentia est inter semel denigrationem et bis denigrationem.Praecipuae partes liquoris denigrandi sunt sodium hydroxidum et nitritum sodium.Temperatura differentia ad nigredinem requisita non magna est, et superficies bona inter 135-155 °C obtineri potest, sed tempus exiguum est longum.
