COLSTAR is a bright engineered nickels platting process which deposits a uniform , corrosion resistant charcoal tone deposit over nickel .

是一种是可以在镍表面形成均匀耐腐蚀镀层的光镍电镀过程。

The directly electroless nickel plating, the stannate conversion processing and the electroless nickel plating on the surface of the magnesium alloys that have formed the stannate chemical conversion film on their surface were researched.

论文摘要：本文以AZ91D合金为研究对象，对其进行直接化学镀镍、锡酸盐化学转化处理以及在形成锡酸盐化学转化膜的镁合金表面进行化学镀镍。

The results show that the impurity formation energy of substitutional P in γ-matrix atom is lower than that of interstitial one.

结果显示磷在镍基体中以代位方式固溶的杂质形成能低于间隙方式，说明磷在镍基体中更易以代位式固溶。

Objective: This study was to investigate the mechanical properties of different brands thermodynamic nickel-titanium archwires under controlled temperature and in artificial saliva to provide some reference for its clinical application.

目的 通过研究不同品牌温控型镍钛弓丝在不同温度和人工唾液环境下的力学性能变化，为临床合理、有效地使用温控型镍钛弓丝提供参考。

The Ni orebodies occur in the laterite weathering crust of the upper part of ultrabasic rocks,which are controlled evidently by landform and belong to the oxidizing deposit of Ni silicate of laterite type in genesis.

镍矿体产于超基性岩上部的红土风化壳中，受地形控制明显，成因类型为红土型硅酸镍氧化矿，以褐铁矿型和腐岩型为主，矿石质量和可利用性均较好。

The content Of isoalkanes decreased when NiSO_4 was loaded, for supported Ni oxidecould promote the dehydrogenation of the precursors of aromatics by unimolecular reactionwhich did not generate negative hydrogen ions, and the carbonium ions could not obtainsufficient negative hydrogen ions to promote hydrogen transfer reaction.

负载氧化镍以后异构烷烃含量下降，氧化镍可以通过脱氢促进芳构化反应，使正碳离子得不到足够的负氢离子饱和使氢转移反应得到抑制。

Histopathological studies on the patients with positive reactions showed slight spongiosis and focal vacuolation in the reaction sites of the skin at 24 h after patch test,as well as slight exocytosis of eosinophils.

为进一步了解镍过敏在广东地区湿疹或皮炎患者中的发生情况，我们采用欧洲标准抗原系列进行斑贴试验，并对不同时相硫酸镍阳性反应皮肤进行组织学观察

In this article,we tried get nickel coating iron powder that don't adhibit impurity in experimentation by electroness plating.

本文采用化学镀的方法，在铁粉上包覆镍粉，以实验过程中不引入其它杂质元素为目的，制备镍包铁复合粉末。

So the cobalt can not only form cobalt self-existent mineral by combining with sulphur or analogous sulphur elements, but also form cobaltiferous sulphides or analogous sulphides and cobaltiferous silicates minerals by isomorphism with Fe, Ni, Mn, Mg, etc.

因此钴不仅可以与硫或类硫元素等离子形成独立钴矿物，而且还可以与铁、镍、锰、镁等离子类质同像，进入铁、镍、锰和镁等矿物晶格，形成含钴的硫化物、类硫化物或硅酸盐。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
