clarain
基本解释
- n.亮煤
英汉例句
- 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。
