Sorpcijske in difuzijske karakteristike tenzijskega lesa : diplomsko delo : visokošolski strokovni študij = Sorption and diffusion characteristics of tension wood : graduation thesis : higher professional studiesKastelic, Miha, 1.5.1982-Tenzijski les (TL) je reakcijsko tkivo listavcev, ki se od normalnega lesa (NL) razlikuje v anatomskih, kemijskih, fizikalnih in mehanskih lastnostih. Večji delež tenzijskega tkiva s svojim ... specifičnim obnašanjem zmanjšuje kakovost lesa in povzroča težave pri obdelavi. Preučevali smo razlike v nekaterih fizikalnih lastnostih med tenzijskim in normalnim lesom bukovine (Fagus sylvatica L.) in ugotovili, da je pri TL v primerjavi z NL krčenje v vzdolžni smeri izrazito večje, manjši pa so volumenski ter radialni in tangencialni skrčki. Nekoliko večja gostota ni statistično značilna. Diferencialna nabreka v radialni (qR) in tangencialni (qT) smeri ne kažeta razlik med kategorijama lesa. Koeficienta nabrekanja v radialni (hR) in tangencialni (hT) smeri ter sorpcijski kvocient (s) so značilno manjši pri TL. Ravnovesne vlažnosti TL so v vsem higroskopnem področju nižje kot pri NL. Tudi povprečna vlažnost točke nasičenja celičnih sten (TNCS) je pri TL za 1,9 % nižja. Difuzijski koeficient TL je neznačilno manjši od difuzijskega koeficienta NL.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
