| 中文摘要 | 应用颗粒物中硅的连续浸提技术,分析了内蒙古西部沙漠两种粒径颗粒物样品中硅的赋存形态和分布特征。结果表明: (1)自然粒径与粒径小于57mum的沙漠颗粒物样品中各形态硅含量分布均为:残渣态硅(Residual-Si) >铁锰氧化物结合态硅(IMOF-Si) >有机硫化物结合态硅(OSF-Si) >碳酸盐结合态硅(CF-Si) >可交换态硅(IEF-Si) ; (2)除OSF-Si外,两种粒径颗粒物样品中各形态硅及SigmaSi含量的分布特征为,粒径小于57mum的样品>自然粒径的样品; (3)颗粒物样品Y1-Y8总硅(SigmaSi)含量分布为,自然粒径:巴丹吉林沙漠(Y_(2-1)) >西居延海(Y_(1-1)) >腾格里沙漠(Y_(4-1)) >库布齐沙漠(Y_(8-1)) >乌兰布和沙漠(Y_(7-1)) >鄂托克旗(Y_(6-1)) >毛乌素沙地(Y_(5-1)) >河西走廊(Y_(3-1)) ,粒径小于57mum:巴丹吉林沙漠(Y_(2-2)) >腾格里沙漠(Y_(4-2)) >库布齐沙漠(Y_(8-2)) >乌兰布和沙漠(Y_(7-2)) >毛乌素沙地(Y_(5-2)) >西居延海(Y_(1-2)) >鄂托克旗(Y_(6-2)) >河西走廊(Y_(3-2)) 。 |
| 英文摘要 | Distribution characteristics and silicon fractions in two sizes of the desert particles from western Inner Mongolia were analyzed with the sequential extraction method. The results showed that: (1) In natural size particles and desert particles that the size less is than 57mum,distribution characteristics of the silicon forms were Residual-Si > IMOF-Si > OSF-Si > CF-Si > IEF-Si > IMOF-Si. (2) In addition to the OSF-Si, the content of both silicon forms and in particles less than 57mum samples were more than that in natural particle sample. (3) The sequence of the total silicon content (SigmaSi) in desert particles with natural particle size was Badain Jaran Desert (Y_(2-1)) >West Juyanhai Lake (Y_(1-1)) > Tenggeli Desert (Y_(4-1)) > Kubuqi Desert (Y_(8-1)) > Ulan Buh Desert (Y_(7-1)) > Eetuoke Qi (Y_(6-1)) > Mu Us Sandy Land (Y_(5-1)) > Zhangye-Hexi Corridor (Y_(3-1)) ,and the sequence of that with particle size less than 57mum was Badain Jaran Desert (Y_(2-2)) > Tenggeli Desert (Y_(4-2)) > Kubuqi Desert (Y_(8-2)) > Ulan Buh Desert (Y_(7-2)) > Mu Us Sandy Land (Y_(5-2)) > West Juyanhai Lake (Y_(1-2)) > Eetuoke Qi (Y_(6-2)) > Zhangye-Hexi Corridor (Y_(3-2)) . |
