clarain

常见例句

• The particle size of clarain declines more rapidly than that of culm.
  燃烧后期, 亮煤的颗粒破碎比灰煤更快；
• The fragmentation of clarain and culm tends to be severely with the increase of particle size, bed temperature and combustion time.
  而暗煤颗粒则因相反的原因不发生破碎或仅发生轻微破碎。
• Clarain from Tongting (Huaibei, Anhui Province, China) bituminous coal was extracted with CS2 using fractional extraction, and then the extracts were analyzed with GC/MS.
  摘要以CS2为溶剂对童亭亮煤进行了按时间段分次取样的索氏溶剂萃取，采用GC/MS对各次萃取物进行了定性分析。
• For clarain, which has a relatively lower density, an extremely low volatile, and a higher fixed carbon content (> 80%), the primary maceral is vitrinite.
  暗煤富含矿物质成分，密度极高但含碳量却很少，热值很低，接近于原煤中的矸石。
• The combustion model of clarain in fluidized bed is equidensity shrinking core model, while that of durain is equidiameter one, and that of culm is a mixed model.
  亮煤在流化床燃烧中服从等密度燃烧模式, 暗煤服从等直径燃烧模式, 而灰煤则服从混合燃烧模式。
• In the early stage of combustion, the mean particle size of clarain decreases promptly as a result of primary fragmentation, but with the time going it falls to a stable size.
  由于破碎, 入炉煤颗粒平均粒径在燃烧早期迅速减小, 而后随着燃烧的进行而逐步趋于一个稳定值；
