鎳銅比
英文
nickel copper ratio-
And then, metal structure with aspect ratio 30 was obtained in our laboratory. eventually, a few micro parts with high aspect ratio were fabricated by liga process under the optimum condition. there were key parts of micro thruster, netlike nickel antielectron modulator, micro copper radiator, stainless steel micro components and many filter mediums with different shapes and dimensions
最後，我們利用liga技術加工的獨特優點，以發展其高深寬比技術的實際應用，先後製作了狹縫陣列鎳結構微推進器關鍵部件、薄壁網狀多孔鎳結構正電子慢化體、微型銅結構換熱氣和多種材料不同、尺寸各異的過濾介質，還結合利用liga技術和微細電火花技術的加工優點，製作出了不銹鋼微結構However, compared with jinchuan ore - bearing intrusion, jianchaling ultrabasic intrusion formed by magma simple emplacement, and magma fractionated weakly with lower content of nickel and sulphur
而與賦存超大型鎳銅硫化物礦床的金川巖體相比，煎茶嶺超基性巖體為巖漿一次侵位形成，分異程度小，鎳、硫含量較低。There are plentiful mineral resources of nickel, cobalt, and copper in the northwest region of china, specially jinchuan superlarge copper - nickel sulflde magmatic deposit in gansu province, known for its large scale and typical metallogenetic feature in the world, is an important source of ni - cu metal mineral resource in our country. in contrast, jianchaling large cobalt - bearing nickel sulflde deposit in shannxi province is not famous and unmined, but many problems about the deposit are researched because of its special geologic settings and mineralization characteristic
我國西北地區有著豐富的鎳、鈷、銅等金屬的礦產資源，尤其是甘肅省金川超大型銅鎳硫化物巖漿礦床，以其超大規模及其典型的成礦特徵而聞名於世，是我國重要的鎳、銅金屬礦產基地，而相比之下，陜西省煎茶嶺大型鎳（鈷）礦床規模較小且未開采，但因其獨特的地質背景和成礦特徵而具有重要的研究意義。( 2 ) the comparative study on pge geochemistry indicated that it exists multiple diagenesis and mineralization in jinchuan superlarge copper - nickel sulflde deposit
（ 2 ）通過鉑族元素地球化學研究，比較論證了金川超大型鎳銅硫化物礦床的多次成巖成礦作用。Compared with jianchaling nickel sulflde deposit, jinchuan superlarge copper - nickel sulflde deposit mostly related with mafic - ultramafic complex that multiple intruded, spatially respected with old huabei block, which formed in marginal rift in middle - new proterozoic
與煎茶嶺鎳礦床相比，金川超大型鎳銅硫化物礦床主要與多次侵入的鎂鐵?超鎂鐵質雜巖有關，空間上與時代相對較老的華北地塊關系密切，形成於中?新元古代的邊緣裂谷。Meanwhile, properties of cobalt - tungsten, nickel, cobalt deposit as copper barrier at temperature between 400 and 800 were compared
同時比較了在400 800下，鈷鎢合金鍍層與鎳層、鈷層的防銅滲能力。This is because an attempt was made in that year to use a more economical, steel plated coin for the one dollar denomination, as against the more expensive cupro - nickel coin that has been in circulation since 1960
事緣在1993年我們嘗試用成本較低的鍍鋼來鑄造1元硬幣，以代替1960年開始使用的比較昂貴的紅銅鎳合金。Tungsten alloys are materials with a high tungsten content and low amounts of nife or nicu
鎢基高比重合金是鎢中加入少量的鎳鐵或鎳銅燒結而成。Particularly as a combined entity would dominate the world mining business as a leading producer of copper, aluminium, uranium and coking coal as well as rivalling brazil ' s cvrd as the biggest supplier of iron ore
特別是作為一個聯合的實體，它在未來將成為世界上很多領域的主要製造商，比如銅、鋁、鎳和煤，同時將成為巴西在鐵礦石供應上的有力競爭者。分享友人
