中文拼音 [wūdāngliáng]
鎢當量
英文
tungsten equivalent-
You should follow the installation instructions for the luminaires, such as installing away from combustible surface ( wall paper, wooden false ceiling ), allowing sufficient room for heat dissipation ( particularly luminaires fitted with tungsten halogen lamps ), ensuring effective earthing connection ( such as adding star and spring washers at the earth terminal ), and adopting proper anchorage to support its weight
燈飾應按照指示安裝，注意要遠離容易燃燒的表面（例如墻紙、木製假天花） ，預留足夠的散熱空間（尤其是裝有鎢絲鹵燈的燈飾） ，確保有效接地（例如在接地終端加上菊花介指和彈弓介指） ，並因應燈飾的重量，選用適當的安裝方法（例如大型的吊燈，須選用拉爆螺絲等） 。Erosive resistance of grey cast iron matrix composite has been investigated, on the condition of different volume fraction of wc and erosive angles and volume fraction of. the results showed that, the erosive resistance of composite with volume fraction of 27 wt % was the best ; volume abrasion rate of composites with different erosive angles was maximum at 50 angle, but volume abrasion rate was less at 0 and 70 angle ; on condition of the same volume fraction of wc and larger size of quartz sand in slurry, volume abrasion rate increased
結果表明：碳化鎢體積分數為27的灰鐵基復合材料的耐沖蝕磨損性能最佳；不同沖蝕角下復合材料的體積碳化鎢顆粒增強鐵基表面復合材料及其沖蝕磨損性能研究摘要磨損量在50 「沖蝕角處最大，在0 」和70 」沖蝕角處較小；在碳化鎢顆粒體積分數相同的情況下，當漿料中的石英砂粒度大時，其體積磨損量增大。Crystalline deposit obtained in low concentration of tungsten and current density, and amorphous or mixture microcrystal deposit obtained in high concentration of tungsten and current density
當鍍液中鎢離子含量低，電流密度低時，鍍層為晶態結構；當鍍液中鎢離子含量高，電流密度大時，鍍層呈非晶態或混合微晶態結構。The recent research status on tungsten heavy alloys was reviewed. the methods to improve the properties of tungsten alloys, including the changes of tungsten particle size, component, content of matrix and the improvements of sintering technics, were also discussed in details. at the same time, some advanced overseas penetrators were introduced and research directions of tungsten alloy materials were pointed out in this paper
