Nanocrystalline InOOH photocatalyst was synthesized from In(NO3)3 and ethylenediamine via a solvothermal method.

以硝酸铟作为前驱体，在蒸馏水和乙二胺的混合溶剂中制备出了InOOH纳米晶，详细地考察了反应溶剂及温度对终产物的影响。

The nanorods of CdS obtained in ethylenediamine were also characfterized be Raman and XPS spectroscopy, these results indicate that the product were in high purity and quality.

在乙二胺中得到的是立方相的CdS纳米棒。用Raman光谱和XPS对所得的CdS纳米棒进行表征，结果表明样品纯度高，质量好

Sodium salt of ethylenediamine tetraacetic acid and glycine）.

乙二胺四醋酸和甘氨酸的钠盐。

The kinds of extractant also effected desulfurization rate .

萃取剂对脱硫率的影响也很大，乙二胺的萃取效果优于甲醇的。

Optimal concentration range of iodine, sulphur dioxide formamide and ethylene glycol in the electrolyte is obtained.

并得到了卡尔·费休试剂配制的电解液中碘、二氧化硫、甲酰胺和乙二醇的最佳浓度范围。

It is revealed that a certain amount of excessive formamide is favorable for preparation of the aerogel with high porosity, while more excessive glycol can deteriorate the formation of nano-porous SiO2 aerogel network. Additionally, the pH value of the reaction system has a strong impact on the microstructure and properties of prepared SiO2 aerogel.

研究发现：微过量的甲酰胺，有利于高孔隙率气凝胶的合成；过量的乙二醇的引入不利于低密度气凝胶的形成；pH值对合成气凝胶的性质也有较大的影响。

In thepreparation of nickel sulfides, nanocrystalline NiS〓 was prepared by solvent-thermaltechnology. By adding a reductive atmosphere in the system, hexagonal phase NiS,which is a metaphase and stable at high temperature, was formed. TEM shows that theparticles are in nanorod shape.

在甲苯中合成了球形的NiS〓纳米粉，并通过还原气氛的调节制备出NiS亚稳相的纳米棒(1000x15nm)，通过前驱物的改变，我们在还原性气氛中还制备出Ni〓S〓纳米粉；同时我们在实验中还发现溶剂对产物的形貌有很大的影响，在乙二胺中作溶剂，分别得到立方形CoS〓和NiS〓及FeS〓纳米棒。

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。
