Core samples from the deeply buried Ordovician Majiagou forma.ion below the Huainan Coalfield(e China) have been investigated for their carbonate types,major and trace elements(including rare earth elements) and C and O isotopes,The objective was to get a better insight into the possible occurrences of gas(and possibly oil) derived from Carboniferous *** was found that the carbonates are dolomites with strongly varying amounts of CaO and *** low concentrations of SiO_(2),Al_(2)O_(3),and Fe_(2)O_(3)indicate deposition in a normal marine environment with little terrigenous input,The Na_(2)O/K_(2)O,Fe/Mn and Sr/Ba ratios,as well as the Ga values indicate mainly a marine salinity and a hot and humid *** slight depletion of Ce and eu,the depletion of heavy rare earth elements(HRee) and the enrichment of light rare earth elements(LRee) indicate deposition in a reducing *** thus appears that the Majiagou forma.ion below the Huainan Coalfield closely resembles that in the eastern part of the Ordos Basin,where several gas reservoirs are present,so that the Majiagou forma.ion under the Huainan Coalfield represents a promising target for hydrocarbon exploration.

Concept learning constructs visual representations that are connected to linguistic semantics, which is fundamental to vision-language tasks. Although promising progress has been made, existing concept learners are still vulnerable to attribute perturbations and out-of-distribution compositions during inference. We ascribe the bottleneck to a failure to explore the intrinsic semantic hierarchy of visual concepts, e.g., {red, blue,···} ∈“color” subspace yet cube ∈“shape”. In this paper, we propose a visual superordinate abstraction framework for explicitly modeling semantic-aware visual subspaces(i.e., visual superordinates). With only natural visual question answering data, our model first acquires the semantic hierarchy from a linguistic view and then explores mutually exclusive visual superordinates under the guidance of linguistic hierarchy. In addition, a quasi-center visual concept clustering and superordinate shortcut learning schemes are proposed to enhance the discrimination and independence of concepts within each visual superordinate. experiments demonstrate the superiority of the proposed framework under diverse settings, which increases the overall answering accuracy relatively by 7.5% for reasoning with perturbations and 15.6% for compositional generalization tests.

压电催化和光催化的耦合被称为压电光催化,作为处理废水最有效的工艺之一,压电光催化在降解有机污染物和微生物消毒方面引起了人们的广泛关注。但是,传统的压电光催化材料往往含铅,其造价昂贵且容易造成二次污染,因此,研究者们在不断探索新型压电材料来驱动压电催化过程。钛酸钡(BaTiO3)作为一种典型的压电半导体材料,其制备成本低、压电活性强、具有优异的压电催化性能,已被广泛用于水分解制氢、二氧化碳还原、细菌消毒和废水处理等多个领域。然而,现有钛酸钡材料存在光生载流子分离率低等问题,实际制备过程中往往需要对其性能进行改进和优化。在此基础上,对BaTiO3的晶体结构、压电光催化原理、极化方式、薄膜制备方法进行了综述,并展望了其未来发展趋势。
