EDS results show that the content of carbon is 7.37% in nano-diamond/Ni brush electroplated composite coating. XRD results show that as the amount of nano-diamond increases, the grain size of coatings becomes smaller.

能谱仪分析结果表明，nano-diamond/Ni复合刷镀层中纳米颗粒特征元素C的质量分数为7.37%。X射线衍射分析结果表明，随着纳米金刚石加入量的增加，镀层表面晶粒尺寸逐渐减小。

The results indicate that the cooling rate of melt droplet that can not break further depends not only on its diameter, but also on its position in atomizing chamber. As a result, the same sized particles in different positions show different cooling rates and two different kinds of microstructures. The cooling rates of melt droplets range from 104 to 108 K/s, and the critical cooling rate for glass formation of Al-Ni-Y is about 105 K/s. Moreover, the corresponding maximum diameter of amorphous particles is 25 μm, which accords well to the theoretical analysis results. The new approach, reflecting the complexity of close-coupled gas atomization objectively, is available and effective to evaluate the cooling behaviors of close-coupled gas atomization.

结果表明：在一定的工艺条件下，紧耦合气雾化存在多种破碎模式，熔滴的冷却速率因直径、雾化位置的差异，相同直径熔滴经历结晶和非晶化2种不同冷却行为；依据Al基合金粉末的粒度分布和微观结构，结合熔体的雾化过程及冷却模式，确定熔滴冷却速率的上、下限；实验得出熔滴的冷却速率为104~108 K/s，Al-Ni-Y合金的非晶化临界冷却速率为105 K/s，能形成非晶态的熔滴最大直径为25 μm左右，实验结果与理论分析结果较吻合，比较客观地反映紧耦合气雾化的复杂过程。

It was observed that not only histidine, but also histidine-Co and histidine-Ni could induce and substitute some Cu and Zn from Cu_2Zn_2SOD, eventually influence the activity of this metalloenzyme. Histidine- metal ion complexes have stronger ability than histidine to displace the bound metal ion from SOD. In addition, the amount of foreign metal ion binding to the SOD was less than that of metal ion lost from SOD. It obviously means that there was apoenzyme in the solution.

实验结果表明： Cu2Zn2SOD酶不仅与组氨酸，而且还可以与组氨酸－CoⅡ）和组氨酸－Ni(Ⅱ相互作用，Cu2Zn2SOD酶中的部分Cu和Zn被诱导和置换出来，并相应地影响了酶的活性；组氨酸－金属离子配合物的作用比组氨酸强，酶活性降低也更明显；酶中结合的外来金属离子的量比从酶上被诱导和顶替下来的金属离子的量要少，说明在溶液中有脱辅基酶的存在。
