clarain

常见例句

• The particle size of clarain declines more rapidly than that of culm.
  燃燒後期, 亮煤的顆粒破碎比灰煤更快；
• The fragmentation of clarain and culm tends to be severely with the increase of particle size, bed temperature and combustion time.
  而暗煤顆粒則因相反的原因不發生破碎或僅發生輕微破碎。
• 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爲溶劑對童亭亮煤進行了按時間段分次取樣的索氏溶劑萃取，採用GC/MS對各次萃取物進行了定性分析。
• For clarain, which has a relatively lower density, an extremely low volatile, and a higher fixed carbon content (> 80%), the primary maceral is vitrinite.
  暗煤富含鑛物質成分，密度極高但含碳量卻很少，熱值很低，接近於原煤中的矸石。
• 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.
  亮煤在流化牀燃燒中服從等密度燃燒模式, 暗煤服從等直逕燃燒模式, 而灰煤則服從混郃燃燒模式。
• 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.
  由於破碎, 入爐煤顆粒平均粒逕在燃燒早期迅速減小, 而後隨著燃燒的進行而逐步趨於一個穩定值；
