A similar discrepancy between EPR and analytical data was found by others in non-stoichiometric V2O5-δ ( d = 0.07 ) prepared by vacuum decomposition of AMV and explained with two consecutive reduction processes ( V5+→V4+→V3+ ) having two rate constants [9] .(Moreover , they found that non-stoichiometric and stoichiometric V2O5 ( obtained by heating V2O5-δ in oxygen at 573K ) , submitted to reduction treatments with propylene , had the same dependence of the V4+ concentration detected by EPR vs. reductiontime .
EPR:电子顺磁共振

电子顺磁共振和分析数据之间的相似的差异被他人在真空分解非化学计量的V2O5-δ ( d = 0.07 )  并将其解释为有两个反应速率常数的两个连续的还原反应( V5+→V4+→V3+ )的过程中发现。 另外,他们还发现 非化学计量的V2O5和化学计量的V2O5(通过将V2O5-δ在氧气中加热到573K获得),经还原处理后都会有丙烯释放,并且通过检测电子顺磁共振和还原时间的关系我们发现他们有着对V4+相同的依赖性。

prepared by vacuum decomposition of AMV and explained with two consecutive reduction processes ( V5+→V4+→V3+ ) having two rate constants [9] 此句是 non-stoichiometric V2O5-δ ( d = 0.07 ) 这种物质的定语。由于本人专业限制,请楼主结合专业知识对翻译中的细节加以修改。
