二乙胺

It is found that the reaction of cadmium nitrate and thiourea in ethylenediamine initially produce lamellar CdS.

硝酸镉和硫脲在乙二胺中反应最初生成薄片状的CdS。

By changing the temperature, the ethylenediamine concentration, pH value and SO2 inlet concentration, and the impacts on the SO2 removal efficiency were investigated.

通过改变吸收剂温度、乙二胺浓度、吸收剂pH和SO2进口浓度，探讨其对脱硫率的影响。

EDA REQUIRED Oct 03, 2009 4 TO 5 FCL ETHYLENEDIAMINE REQUIRED CIF NHAVA SEVA INDIA...

的EDA需2009年10月3日4至5级集装箱乙二胺的到岸价格感应加热元件所需感应炉坩埚印度孟买新港舍瓦。。。

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。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
