察尔汗盐湖资源开发存在的问题初探

察尔汗盐湖资源的开发对于促进我国的农业发展具有十分重要的意义，文章从湖区生态环境；资源品种多不稳定；资源配置不合理；分布广，开发难度大；单一开采模式；开采方式落后等几个方面详细阐述了察尔汗盐湖资源开发存在的问题。     

七彩万花筒

用鼻孔饮酒越南北部地区有一个叫空塞的少数民族。他们饮酒时,在酒壶中插一支细长的竹管,一边往嘴里送菜,一边用手提酒壶,把细竹管放到鼻孔里,把酒吸进去。这种饮酒方式真是世界罕见。     

察尔汗盐湖固液矿转化实验研究

研究察尔汗盐湖光卤石中的钾在固液矿间的转化规律.实验考察转化过程中液相组成随时间的变化.固液相钾含量分别在0.42%～3.71%和3～11.94 g/L时,钾均可从固相向液相转化,钾转化率和转化速率随温度的升高而增大;随固液矿中钾浓度差异增加而增大.用Stumn溶解动力学方程处理实验数据,得到满意结果.     

Branched aliphatic alkanes of shell bar section in Qarhan Lake, Qaidam Basin and their paleoclimate significance

Blomarkers of paleolake deposits from Qarhan Salt Lake in Qaidam Basin, northwest China were systematically analyzed and the A--C series compounds of branched aliphaUc alkanes with quaternary substituted carbon atom （BAQCs） were identified. The homologous distinguished three series, A-C, were identified as 5,5-diethylalkanes, 6,6-diethylalkanes and 5-butyl, 5-ethylalkanes series, and their relative abundance was A 〉 B 〉 C. Series A and C were characterized by odd carbon numbers, whereas series B was characterized by even carbon numbers. The high values of series A corresponded with the high values of series B and C. Therefore, it can be concluded that series A, B and C possess a similar biological origin. The abundance of series A was relatively low in the lower part of the section compared with that in the upper part, implying that these series originated from bacteria and/or algae more prevalent in fresh-mesohaline water, and such kinds of bacteria and/or algae are most likely to be thermophilous species. The A25/nC25 ratio differences in the section show that such branched aliphatic alkanes can be treated as one kind of environmental change proxy for paleolake evolution and may provide important information for the climate reconstruction of the Late Pleistocene.     

水氯镁石先进脱水技术工程化研究开发

无水氯化镁作为一种重要的化工产品,广泛用于石油、化工（工业催化）、医药等工业领域;作为较佳的有色冶金原料,水氯镁石脱水制备无水氯化镁,进而电解生产金属镁是一个困扰中国有色金属行业20余年的技术难题,引起学术界和工业界的广泛关注。有效开发利用察尔汗盐湖的镁资源,形成盐湖化工与天然气化工有机结合的产业链,国家和青海省地方政府非常关注并给予多方支持和指示。     

察尔汗盐湖开采引发的地质环境问题及对策研究

在研究青海省察尔汗盐湖矿山开采引发的地质环境问题基础上,提出存储性排卤、调节性排卤和尾卤淡化回灌采区三种排卤方案,并通过尾卤排放方案合理性分析指出调节排卤及其延伸尾卤淡化回灌采区方案能够使老卤得到充分的利用,并且不会造成富集的组份再次流失,排卤后不会造成新的环境地质问题,为目前唯一行之有效的尾卤排放方案。
