The results of further experiments show that most of the metallic oxides give a catalytic effect on NO/CO reaction, while pre-reduced Ni2O3 sample shows remarkable catalytic activity to the direct decomposition of NO.

Under the experimental conditions, the evaluation of catalytic activity on direct decomposition of NO show that the presence of Cu is necessary for improving activity at 600~800℃ among La0.9Ce0.1Fe(subscript 0.8-x)Co0.2YO3(Y=Cu, Zn, Ni) series, and in which L.a0.9Ce0.1Fe0.7Co0.2Cu0.1O3 has the highest activity, the conversion of NO decomposition maintains 80% and nearly 100% at 750℃. H2-TPR result proves that the higher activity is related to the mobility of lattice oxygen which is beneficial to the reproduction of active site for NO decomposition.

在实验条件下，对NO的活性测试结果表明，L0.9Ce0.1Fe(下标 0.8-x)Co0.2YO3(Y=Cu， Zn， Ni)系列催化剂在600~800℃范围内，掺杂Cu的复合氧化物具有较高的催化分解活性，其转化率始终保持在80%以上，反应温度为750℃时，几乎100%转化。H2-TPR结果证明，其催化分解活性高的原因是Cu的掺入使晶格氧活动性增强。

In order to research the effects of minimum tillage and no-tillage patterns on yield and senescence of flag leaf of winter wheat, four tillage patterns were adopted in Longkou city, Shandong Province, China for three years. Four tillage patterns were as follows: conventional tillage with straw turnover, rotary tillage with straw turnover, serrated disk harrow tillage with straw turnover, no-tillage with straw cover. Effects of different tillage patterns on the activities of superoxide dismutase, peroxidase and the contents of malondialdehyde and soluble protein of the winter wheat flag leaves after anthesis were analyzed.
