The partial oxidation of methane by the H5PV2Mo10O40 catalyst in oleum was studied. The effects of catalyst amount, reaction temperature, reaction time, and sulfur trioxide concentration on the methane conversion and methanol yield were investigated.

以H5PV2Mo10O40 为催化剂，在发烟硫酸中进行了甲烷液相部分氧化，考察了催化剂用量、反应温度、反应时间和发烟硫酸浓度等工艺条件对反应收率的影响。

The mechanism of V2O5 catalytic cycle for methane partial oxidation in oleum was discussed and the macro-kinetic model was deduced.

甲烷在部分氧化反应中首先转化为硫酸甲酯，后者进一步水解得到甲醇。

In order to find the opposable position between substrate and the center of plasma, we fixed the power at 800 Watt and the working pressure at 45 Torr.

固定功率800 Watt、工作压力45 Torr、甲烷与氢气之浓度比例0.25%，於(100)矽基材上进行钻石薄膜的合成。

We hope that the understanding on the reactivity of gas-phase osmium oxide cations with methane is helpful for the design of catalyst for the similar reactions.

所以甲烷和乙烯中C-H键的活化具有重大的经济和环境价值，也是最具基础意义的化学前沿课题之一。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
