水文资料整编是形成水文监测成果的重要环节,随着水文监测的自动化程度越来越高,数据采集量大幅度增长,大量的数据处理成为水文资料整编的一大难题.本文尝试采用"折线逼近法",对水文遥测数据进行精简处理,尽可能地减少摘录数据量,用最少的摘录数据构成的折线来模拟实际水文要素的变化过程,并使其过程不失真,满足规范要求,便于水文年鉴刊印.该方法在江苏省水文遥测数据直接整编程序软件编制过程中得到应用,获得了较好的效果.  相似文献

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

流量测验一般分为常规测验和精简测验方法,而垂线精简方案是降低水文测站人员工作强度,缩短测流时间的有效方式。以新疆喀什地区某水文测站为研究对象,对流量测验垂线进行精简分析,在满足测验精度要求的前提下,对精简后的流量测定精度进行评定,分析精简方案的可行性。结果可知:垂线精简下的水位~流量关系检验的系统误差、标准差以及随机不确定度也均可满足《河流流量测验规范》GB50179-2015的允许误差要求,精简方案切实可行。  相似文献

Pant-y-ffynnon Quarry in South Wales yielded a rich cache of fossils in the early 1950s, including articulated specimens of new species (the small sauropodomorph dinosaur Pantydraco caducus and the crocodylomorph Terrestrisuchus gracilis), but no substantial study of the wider fauna of the Pant-y-ffynnon fissure systems has been published. Here, our overview of existing specimens, a few described but mostly undescribed, as well as freshly processed material, provides a comprehensive picture of the Pant-y-ffynnon palaeo-island of the Late Triassic. This was an island with a relatively impoverished fauna dominated by small clevosaurs (rhynchocephalians), including a new species, Clevosaurus cambrica, described here from a partially articulated specimen and isolated bones. The new species has a dental morphology that is intermediate between the Late Triassic Clevosaurus hudsoni, from Cromhall Quarry to the east, and the younger C. convallis from Pant Quarry to the west, suggesting adaptive radiation of clevosaurs in the palaeo-archipelago. The larger reptiles on the palaeo-island do not exceed 1.5?m in length, including a small carnivorous crocodylomorph, Terrestrisuchus, and a possible example of insular dwarfism in the basal dinosaur Pantydraco.  相似文献

The solubilities of columbite, tantalite, wolframite, rutile, zircon and hafnon were determined as a function of the water contents in peralkaline and subaluminous granite melts. All experiments were conducted at 1035 °C and 2 kbar and the water contents of the melts ranged from nominally dry to approximately 6 wt.% H2O. Accessory phase solubilities are not affected by the water content of the peralkaline melt. By contrast, solubilities are affected by the water content of the subaluminous melt, where the solubilities of all the accessory phases examined increase with the water content of the melt, up to 2 wt.% H2O. At higher water contents, solubilities are nearly constant. It can be concluded that water is not an important control of accessory phase solubility, although the water content will affect diffusivities of components in the melt, thus whether or not accessory phases will be present as restite material. The solubility behaviour in the subaluminous and peralkaline melts supports previous spectroscopic studies, which have observed differences in the coordination of high field strength elements in dry vs. wet subaluminous granitic glasses, but not for peralkaline granitic glasses. Lastly, the fact that wolframite solubility increases with increasing water content in the subaluminous melt suggests that tungsten dissolved as a hexavalent species.  相似文献

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.
