The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.

喹啉和DHQ对苯胺的HDN反应有强烈的抑制作用，喹啉在磷化镍催化剂上几乎全部通过完全加氢饱和路径进行反应。H_2S和二苯并噻吩强烈地吸附在磷化镍催化剂活性中心上，阻碍了反应物分子的吸附，从而对喹啉的HDN反应有强烈的抑制作用。

The effects of such parameters as temperature, pH, feeding rate,concentration, [NH_3]_T/_T molar ratio, surfactants and agitation, on the morphology and size of the particles, were studied and conclusions obtained are as follows:(1) The morphology and size of the particles are mainly decided by the species of nickel oxalates present.(2) Speeding up dissolution-recrystallization process benefits the preparation of the particles of being composed of a single species with uniform morphology and high aspect ratio.(3) The variations of nucleation and growth supersaturation under different conditions have definite effects on the morphology and size of the particles.(4) Adding PVP25 at a proper amount is beneficial to the preparation of fibrous nickel oxalate particles with high aspect ratio. 3 The formation mechanism as well as the morphology and size control of fibrous cobalt oxalate particlesThe cobalt oxalate particles with fibre morphology were prepared using CoCl_2 solution and mixed(NH_4)_2C_2O_4, NH_3·H_2O solution by a double jet process.

研究了温度、pH值、加料速度、浓度、[NH_3]_T/_T摩尔比、表面活性剂及其添加量、搅拌等对颗粒形貌与粒度的影响，主要结论为：(1)草酸镍化合物种类是决定颗粒形貌与粒度的最主要因素；(2)提高陈化中溶解—再结晶速度，有利于得到物相单一，形貌规整，轴向比大的粉末；(3)不同条件下，颗粒形核与生长过饱和度改变，也会对粉末形貌与粒度产生一定影响；(4)适量添加PVP25有利于大轴向比纤维状草酸镍的制备。3纤维状草酸钴的形成机理及其形貌与粒度控制采用CoCl_2溶液与(NH_4)_2C_2O_4和NH_3·H_2O混合溶液并流加料合成的方法，研究了纤维状草酸钴的制备。

It was composed of 75% silver and 25% copper, had a six-pointed star on one side, a Roman numeral III on the other, and — weighing in at four-fifths of a gram — was the lightest coin ever produced by the US Mint. The silver three cent piece was discontinued by the Coinage Act of 1873; at that time, a three cent nickel coin was issued, made up of copper and nickel and slightly larger than the silver version.

改硬币是由75%的银和25%的铜铸造，图案的一面有一个六角星，另一面是罗马数字III，重量只有1克的5分之4 -这枚硬币是美国造币厂有史以来发行的最轻的硬币。1873年通过的《硬币法案》，停用了这种硬币；与此同时发行了由铜和镍铸造的3美分镍币，这种硬币比银版硬币略大一些。

To compare with general nickel coated steel strip, our steel strip with electrodeposited nickel coating is provided with more excellent processing capability and anti-corrosion capability. It can be applied to produce battery steel shell such as alkaline battery, electricizable battery, button cell, etc. This product has already been the developing trend of battery industry instead of actual rolling plating battery steel shell.
