Through the determination of 2-chlorobenzaldehyde and benzalacetone in additive for electroplating, the method was proved to be accurate, simple and rapid.

建立的方法用于电镀添加剂中邻氯苯甲醛、苄叉丙酮含量的测定，结果准确，操作简便、快速。

Benzaldehyde and acetone used as materials,the benzylidene acetone is synthesized in the presence of potassium fluoride on alumina.

以苄叉丙酮为主光亮剂、OP-10为载体光亮剂，并加入适量的辅助光亮剂，复配出Zn-Mn合金电镀添加剂ZM。

Benzylidene acetone desorption potential acid sulfate tin plating solution is very close to the ideal desorption potential; Benzylidene acetone, formaldehyde can regulate the desorption potential role and can increase the current density range; Composite additive D can make acid sulfate tin plating solution in the hydrogen produced during the rapid detachment; Ammonium metavanadate can catalyze Sn4+ and restore to Sn2+, and then make solution stability.

苄叉丙酮的脱附电位很接近酸性硫酸盐镀锡溶液的理想脱附电位；甲醛具有调节苄叉丙酮脱附电位的作用，并且能够增大电流密度范围；复合添加剂D能够使酸性硫酸盐镀锡溶液在电镀过程中产生的氢气迅速脱离；偏钒酸铵能够催化Sn4+还原为Sn2+，从而使镀液稳定。

The influences of plating process parameters, such as sulphamate concentration, electrolyte pH value and temperature, and pulse parameters, such as cathodal current density, pulse current frequency and duty cycle, on the micro-hardness of the nickel deposit has been studied by orthogonal experiments.

利用正交试验法分析研究了主盐氨基磺酸镍浓度、电镀过程工艺参数及脉冲参数（阴极电流密度、脉冲频率和占空比）对镀层显微硬度的影响；并对相关参数进行了优化。

The results show that the technical parameters and the concentration of sodium molybdate have obvious effect on the composition of the alloy. The crystal grain size is from 6.2 to 12.7 nm and changes with current density, temperature and the pH value of the electrolyte.The crystalline growth of the alloy accords with the model of three-dimensional growth. The surface morphology is mainly determined by the rate competitions between the growing direction of vertical surface and the expanding direction along the surface towards circumambient. The results of the X-ray data show the presence of the multiphase containing solid solution and intermetallic compound in the deposits. The deposit phases alter from the FeNi and FeMo solid solution to the FeNi and MoNi4structure at 3 A/dm2. The deposits internal stress increases linearly with the decrease of the grain size. The lattice parameter of the deposits are slightly distorted

结果表明：工艺条件和钼酸钠浓度对合金组成的影响较大；所得合金晶粒尺寸为6.2~12.7 nm，并随电流密度、温度和电镀液的pH值的改变而变化；合金的晶体生长符合晶核三维生长模型，镀层表面形貌由平行和垂直于基体的生长速度的相对大小决定；镀层物相为固溶体和金属间化合物的多相结构，当电流密度为3 A/dm2时，镀层物相由FeNi和FeMo固溶相转化为FeNi和
