目前,许多水文测站在使用上海气象仪器厂生产的HCJ_1型自记水位计时,都是将记录纸倒装在转筒上,记录笔尖从右向左运行,所绘的水位过程线是反向的。这样,为摘录与整编水位资料带来很大不便,并因此水位数据容易发生错误。为了克服上述缺点,我们作了一点改进。即将原仪器的钢丝轮重新钻孔(如图)。原钢丝轮上的穿孔在b、c位置,现在a、d位置重新钻两个小孔,这 相似文献

在大沽河地下水源地自然地理、地质和水文地质条件调查的基础上,系统地收集和整理了钻孔属性信息、地下水水位和水质监测数据,构建了基于Microsoft SQL Server基础数据库和Hydro Geo Analyst信息管理平台的大沽河地下水源地信息管理系统。该系统解决了数据存储不规范、查询提取困难、缺乏系统管理和利用效率低等问题,实现了数据资料的存储、查询和可视化展示,帮助管理者快速、准确、全面地掌握大沽河地下水源地地层和岩性分布、地下水水位和水质的动态变化趋势与空间分布特征。本系统为大沽河地下水源地的合理开发、管理和污染治理提供了数据和技术支持,具有重要的理论意义和实际应用价值。 相似文献

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ1 roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
