本文报道了N-2闪烁猝灭效应的研究。我们的主要兴趣是找到一种实用的气体，大大减少了在空气中的闪烁产额。我们研究了N-2中的O、CO_2和CH_4，并测定了它们的Stern-Volmer常数。当在混合物中使用两种猝灭气体时，发现效果是相加的。讨论了这些气体的猝灭机理，并报道了它的实际应用。(C)2004 Elsevier B. V.保留所有权利。
We report on the studies of quenching effects in N-2 scintillation. Our main interest is to find a practical gas that reduces the scintillation yield in air substantially. We have studied O, CO2, and CH4 in N-2, and have determined their Stern-Volmer constant. When two quenching gases are used in a mixture, the effects are found to be additive. The quenching mechanism of these gases is discussed and its practical application is reported. (C) 2004 Elsevier B.V. All rights reserved.
