对“提升基础地质调查服务能力”新要求的理解与思考

《浙江省自然资源发展“十四五”规划纲要(征求意见稿)》,对基础地质工作提出了“提升服务能力”的新要求,具体是:全面推进区域地质调查、城市地质调查、水工环地质调查、地球物理和地球化学调查,建立基础地质核心数据库;开展精细化土地质量地质调查和天然富硒土地资源详查,建立土地质量地质调查数据库;推进生态功能区和海岸带等综合地质调查.

矩形虾池环流的流动特点与流动阻力

对矩形虾池在水车式增氧机作用下产生的环流特点进行理论分析，结果表明，在转角处会形成涡旋，边壁附近在一定条件下会产生回流；利用ANSYS软件的FLOTRAN CFD进行数值计算，获得与理论分析一致的结果，与现场实际情况吻合。并进一步对虾池阻力进行分析，提出了一些减阻措施。     

穆珠朗玛峰地区土壤中稀土元素的含量和分布

本文论述了珠穆朗玛峯地区土壤中稀土元素的含量,以及它们在土壤中的分布模式,并发现土壤中稀土元素的含量水平在很大程度上受土壤母质的制约。     

Geochemical survey of thermal system in Northeast China and their geothermometric characters

The chemical composition of several thermal springs around Changbaishan area has been investigated. Cenozoic basaltic rocks are widely distributed in Northeast China and geothermal characteristics have been described. About one hundred hot springs exist around Changhaishan Volcano at the border between China and D.P.R.Korea with high temperature about 82~C. The pH values of the spring water range from 6.9 to 7.1 and the total flow rate is about 4.8 L/sec. The chemical composition of the thermal springs is sodium carbonate; the high-mineral contents of thermal water are believed to have medicinal properties. Bathhouses are already built along the hot springs to take the advantage of the supposed healing properties. The high quality of those hot springs is believed to be utilitized for mineral water. The chemical equilibrium temperatures were estimated at about 160℃ based on the Na-K-Ca geochemical thermometer.
