查询词典 tungsten

The research indicates the Chinese tungsten industry management condition turns better continuously, the performance level raises year by year, the profits is swimming from downstream to upwards tungsten mineral mountains But the index number of Lerner makes know that the Chinese tungsten industry still competes too heavy over a long period of time.(6) On the base of above analysis, this paper puts forward that the target mode of Chinese tungsten industry market structure development is oligopoly, the goal of production structure optimization is to develop high worthy affixture production, so make tungsten industry profits distributes in value link of the mining and mill run, smelt, deeply process.

研究表明，中国钨产业运营状况的不断好转，绩效水平逐年提高，利润正从下游逐渐往上游钨矿山倾斜；但勒纳指数表明，中国钨产业还长期处于过渡竞争状态。6、基于以上分析，提出中国钨产业市场结构发展的目标模式是实现有效竞争的市场格局；产品结构的优化目标是大力发展高附加值的钨产品，使钨产业链各环节的利润按硬质合金、钨矿山和冶炼次序来分布。

In the different zoning of xenoliths, molybdenum and tungsten contents is lower and homogeneous,and be lower than the world\'s average abundance; tungsten compared to molybdenum,the content more homogeneous in xenoliths, compared to mantle\'s average abundance more less. This explains the geochemistry incompatible character homophyly and diversity of molybdenum and tungsten determined their trend enrichment in crust in the course of the mantle evolution and magmatism, among molybdenum more trend enrichment in lower crust but tungsten in middle-upper crust.

包体不同带中，钼、钨的含量较低且较为均一，并低于世界均匀丰度；钨和钼相比，其在包体中的含量更为均一，相对于地幔均匀丰度更小，说明钨、钼的地球化学不相容性的类似性和差异性决定了它们在地幔演化和岩浆过程中倾向富集于地壳中，其中钼更倾向富集于下地壳，钨则更倾向富集于中上地壳。

Although be in short-term inside , the United States can offer the benefit in be more than the condition that seek from the inventory of primary tungsten product such as acid of concentrate , tungsten and oxidation tungsten as before many , but should realise , get primary tungsten incontinently to taste inventory from other area , then have a change of luck goes to the United States such the market puts in in order to sell a system of fixed quotas for grain production in the country , as a result changes the practice that supply and demand balances , give the place inevitably of all kinds the industry related to tungsten brings menace .

虽然在短期内，美国依旧能够从精矿，钨酸与氧化钨等初级钨制品库存供大于求的形势中获益不少，但是应该熟悉到，从其它地区无节制地获取初级钨品库存，进而转运到美国这样的以销定产国家中并投放市场，以致改变供需平衡的作法，将不可避免地给该处各类与钨相关的行业带来威胁。

The results indicate that only tungsten oxide grains are formed without sodium sulfate additions, while tungsten oxide whiskers with 0.20.3 μm in diameter and aspect ratio of 5-50 or tungsten oxide nanowires with 1030 nm in diameter and aspect ratio of 50200 are synthesized by some sodium sulfate additions on conditions at 180 ℃ for 1236 h.
