Petrographic and geochemical characteristics of the Upper Triassic sandstones in the western Ordos Basin were studied to provide insight into weathering characteristics,provenance,and tectonic *** features show that the sandstones are characterized by low-medium compositional maturity and textural *** CIA and CIW values reveal weak and moderate weathering history in the source *** geochemical characteristics together with palaeocurrent data show that the northwestern sediments were mainly derived from the Alxa Block with a typical recycled nature,while the provenance of the western and southwestern sediments were mainly from the Qinling-Qilian Orogenic *** tectonic setting discrimination diagrams signify that the parent rocks of sandstones in the western and southern Ordos Basin were mainly developed from continental island arc,which is closely related to the evolution of the QinlingQilian Orogenic ***,the sandstones in the northwestern Ordos Basin show complex features,which may be resulted from a typical recycling *** evidence from petrography,geochemistry and sedimentology,together with previous researches suggest the Kongtongshan and Helanshan areas were the southwestern and northwestern boundary of the Ordos Basin,respectively,and there was no clear boundary between the Hexi Corridor Belt and Ordos Basin,where a large,uniform sediment dispersal system developed during the Late Triassic.

First discovery of Late Triassic tuffs in the South Qilian Basin: geochemical characteristics， zircon LA-ICP-MS U-Pb ages and potential source regions

Journal of Earth Science 2021年

作者： Fangpeng Du Furong Tan Shiming Liu Xiaochen Zhao yingtao chen Junwei Qiao College of Geology and Environment， Xi'an University of Science and Technology Shaanxi Provincial Key Laboratory of Geological Support for Coal Green Exploitation China National Administration of Coal Geology Shaanxi Institute of Geological Survey School of Energy Resource， China University of Geosciences

This investigation reports the first discovery of more than 70 tuff intervals in the Upper Triassic， South Qilian Basin. Petrographic and geochemical analyses were carried out on ten tuffs and zircon U-Pb dating were on three. Thin section and X-ray diffraction （XRD） results indicate that the tuffs were composed of crystal shards and altered glass shards; crystal shards include plagioclase and quartz. Most of the tuffs had been transformed into illite/smectite mixed-layers （I/S）. In addition， calcite， pyrite， dolomite and siderite were also identified in some tuffs. Analysis of major elements suggests that the tuffs are a peraluminous high-K calcalkaline series. Trace elements results indicate that the tuffs were enriched in high field strength elements （HFSE）， including Th， U， Ta， Zr and Hf. Geochemical characteristics suggest that the tuffs originated from comendite pantellerite and rhyolite from within plate settings. Zircon U-Pb dating （236.0 ± 1.7 Ma， 231.4 ± 1.6 Ma and 223.1 ± 3.9 Ma） indicate that the tuffs were erupted in the Late Triassic. Comparative chronology and geochemical analyses suggest that the West Qinling Belt and the East Kunlun Belt are the potential source regions of these tuffs， and they originating from the within plate magma during a post-collisional period.

1963年，美国年轻的哲学教授葛梯尔在《分析》杂志上发表了“确证的真信念是不是知识”一文，该文篇幅虽短、共不足三页，但却对知识的经典定义“知识是确证的真信念”造成了毁灭性打击。

基于对内在论与外在论、基础论与融贯论等当代知识论主流理论的批判,索萨(ErenstSosa)建构了新的知识理论:德性知识论。德性知识论的提出对当代知识论研究具有导向性的意义,也可以说,引领了当代知识论的合理重建。但该理论仍然受到主流学者的围剿,并没能有效完成知识论的重建任务。

为提高燃气轮机涡轮导叶的可靠性及其使用寿命,引入变温循环冷气的概念,以某涡轮叶片为例,开展了燃气涡轮叶片热冲击循环疲劳寿命研究,对燃气轮机涡轮导叶进行启-停循环载荷谱下的应力状态的三维流固热耦合有限元分析,针对叶片在变温循环冷气的热冲击应力变化规律,得到叶片在循环中的稳态与过渡态下的温度场、应力场分布,之后对各个计算工况下的叶片结构强度与疲劳寿命进行分析与评估。搭建试验台,对该型燃气轮机涡轮导叶进行定温冷气循环下的热冲击疲劳试验,与有限元分析结果进行比对,得到结论:三维流固热耦合有限元分析所得叶片应力较大区域为叶片尾缘及叶盆中部,与热冲击试验所得破坏区一致,通过改变冷气循环温度可有效地提高叶片热疲劳寿命。

随着我国高速铁路的快速发展,推广大跨度铁路简支箱梁既能扩大简支梁的适用范围,也可取得更好的经济性。UHPC材料具有超高强度、超高韧性和超长耐久性等优异特性,采用UHPC材料建造大跨度铁路简支梁可以实现桥梁轻型化并减小下部结构费用。通过对跨度56 m UHPC薄壁简支箱梁设计分析,结果表明:(1)56 m UHPC薄壁简支箱梁比同等跨度普通混凝土简支箱梁可减轻梁重35%;(2)薄壁箱梁所采用UHPC材料工作性能需满足自密实混凝土工艺要求;(3)56 m UHPC简支箱梁剪力滞效应不明显,结构稳定性和车桥耦合分析结果均能满足规范要求。UHPC材料对于增加高速铁路简支梁跨度具备优势,可作为今后高速铁路简支梁发展方向,该材料在桥梁领域具有广阔的应用前景。
