利用X射线吸收近边结构（XANES）分析了11种轮胎中硫的化学状态，以区分不同的轮胎橡胶。所有轮胎在2471.5和2480.5 eV附近具有峰，并且这些峰的形状和高度在轮胎之间不同，这表明硫的化学状态可以用于区分轮胎橡胶。基于XANES结果的t检验，55个组合中有43个在5%的显著性水平上不同。(C)2015爱思唯尔爱尔兰有限公司版权所有。
The chemical states of sulfur in 11 tires were analyzed using X-ray absorption near-edge structure (XANES) in order to discriminate between various tire rubbers. All tires had peaks around 2471.5 and 2480.5 eV, and the shapes and heights of these peaks differed among tires, suggesting that the sulfur chemical state could be used for discrimination between tire rubbers. Based on t-tests on the results of XANES, 43 of 55 combinations were different at a significance level of 5%. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
