The result indicated that the purification methods presented could result in high recovery ratio, high purity, mildoxidation condition, and easy control of test in contrasted with other ones.
结果显示，该提纯方法比其它方法回收率高，纯度高，氧化条件柔和，实验过程易于控制。

In the contrast, the effect of the kind of catalysts on oxidation of alkane under mild condition has been paid little attention.
相比之下，在氧化条件下，对此类催化剂催化烷烃反应研究的不多。

The wear mechanisms are changed with the load, it shows oxidation and abrasive wear at low load, abrasive and mild delamination wear at medium load, and delamination wear at high load.
