本文研究沪港通的实施对A-H股溢价的影响。本文发现,在沪港通实施后的短期内,主要是香港和海外的投资者通过沪股通投资沪市股票,A-H股溢价增加。该现象不符合"一价定律"。从长期而言,内地投资者通过港股通投资香港股票,使得... 本文研究沪港通的实施对A-H股溢价的影响。本文发现,在沪港通实施后的短期内,主要是香港和海外的投资者通过沪股通投资沪市股票,A-H股溢价增加。该现象不符合"一价定律"。从长期而言,内地投资者通过港股通投资香港股票,使得溢价回落。我们进而发现,同一家公司在沪市和港市上共同的信息对资金流向影响不大,但是单边市场上的特有信息对资金流向的影响明显,可以看出新兴市场投资者进入新开放市场存在着相对更长的"学习过程"。 展开更多

Photocatalytic water splitting and carbon dioxide photoreduction are considered eff ective strategies for alleviating the energy crisis and environmental pollution.Polynuclear metal-oxo clusters possess excellent electron storage/release ability and unique catalytic properties via intermetallic synergy,which enables them with great potential in environmentally friendly photosynthesis.Importantly,metal-oxo clusters with precise structure can not only act as high-effi ciency catalysts but also provide well-defi ned structural models for exploring structure-activity relationships.In this review,we systematically sum-marize recent progress in the catalytic application of polynuclear metal-oxo clusters,including polyoxometalate clusters,low-cost transition metal clusters,and metal-oxo-cluster-based metal-organic frameworks for water splitting and CO_(2)reduction.Furthermore,we discuss the challenges and solutions to the problems of polynuclear metal-oxo clusters in photocatalysis. 展开更多

Sophora alopecuroides L.,a perennial plant belonging to Leguminosae family,is used as medicinal materials to treat a variety of skin diseases.Its chemical components are complex and diverse,mainly including alkaloids and flavonoids.Modern pharmacological studies have found that the isolated compounds from S.alopecuroides have a variety of pharmacological activities.In particular,alkaloids represented by matrine,aloperine and oxymatrine have significant anti-inflammatory,anti-viral,anti-tumor,anti-bacterial and immunomodulatory activities.This paper summarized the chemical constituents and pharmacological activities of S.alopecuroides,aiming to provide the basis for further research. 展开更多

The deficient agricultural water caused by water shortage is a crucial limiting factor of horticultural production.Among many agricultural water-saving technologies,regulated deficit irrigation(RDI)has been proven to be one of the effective technologies to improve water use efficiency and reduce water waste on the premise of maintaining the quality of agricultural products.RDI was first reported more than 40years ago,although it has been applied in some areas,little is known about understanding of the implementation method,scope of application and detailed mechanism of RDI,resulting in the failure to achieve the effect that RDI should have.This review refers to the research on RDI in different crops published in recent years,summarizes the definition,equipment condition,function,theory illumination,plant response and application in different crops of RDI,and looks forward to its prospect.We expect that this review will provide valuable guidance for researchers and producers concerned,and support the promotion of RDI in more horticultural crops. 展开更多
