Description	Zhášení pink afterglow dusíku vlivem uhlovodíkových příměsí je studováno v proudícím režinu. V okolí bodu pozorování byla měněna teplota Pyrexové stěny reaktoru v rozmezí od teploty kapalného dusíku po pokojovou teplotu. Byla pozorovány spektra prvního adruhého pozitivního a prvního negativního systému neutrálího molekulárního dusíku a fialový a červený systém radikálu CN. Vibrační populace stavů N2 (B), N2 (C) a N2+ (B) byly silně snižovány přičemž tento efekt byl silnější při snižování teploty. Vibra ační populace stavů CN (A) a CN (B) jsou za pokojové teploty v podstatě nezávislé na koncentraci uhlovodíků, s klesající teplotou ale rostou. Práce podává i zjednodušený model kinetických procesů probíhajících za daných experimentálních podmínek. (cs) The effect of the nitrogen pink afterglow quenching by hydrocarbon traces is studied in the flowing afterglow regime. The Pyrex wall temperature around the observation point was varied between the ambient and liquid nitrogen temperature. The spectra of nitrogen first and second positive and first negative bands and CN violet and red systems were observed. The strong quenching of the vibrational populations of the nitrogen N2(B), N2(C) and N2+(B) states was observed and this effect increases with the deccreasing wall temperature. The vibrational populations of CN(A) and CN(B) states are more or less independent of the hydrocarbon concentration at the ambient wall temperature, but they increase with the decreasing temperature. A simplified kinetic model of the processes at our experimental condition is presented, too.
