二叠系风城组是玛湖凹陷主力烃源岩和勘探层系,落实深层—超深层页岩油气潜力对玛湖凹陷勘探具有重要指导意义。基于风云1井风城组页岩气发现及前风城组油气勘探成果,系统分析该井的岩性发育特征、烃源岩成烃条件和储层条件,明确玛湖凹陷风城组页岩油气系统中页岩油、气分布序列特征及油气地质意义。研究表明,风云1井风城组岩性主要为盐岩、页岩与粉—细砂岩等;风城组烃源岩有机质丰度总体较低,其中风一段烃源岩最为发育,平均有机碳含量达1.06%;储层整体致密,孔隙度平均为4.65%,其中云质页岩和灰质砂岩储集性能较好。此外,随深度增大玛湖凹陷风城组具有完整的由页岩油、页岩油气到页岩气的演化规律。前风城组油气来源于超深层的另一油气系统,应是下一步勘探的重要领域之一。

2β,3α--Dihydroxyurs-12-en-28-oic acid （6） is a naturally occurring diastereoisomer of corosolic acid with glycogen phosphorylase inhibitory activity. A new strategy for the semi-synthesis of 6 was developed. Using the commercially available ursolic acid （1） as the starting materials, 6 was synthesized through five facile reactions with a high stereoselectivity and an overall yield of 47,3%, The structure of 6 was confirmed by optical rotation, ESI-MS, 1H NMR and 13C NMR data,

The excited-state intramolecular proton transfer molecules based on chalcone （E）-3-（4＇-dimethylami- nophenyl）-l-（4＇-fluoro-2＇-hydroxyphenyl）-2-propen-l-one （DMF-HPPO） have been synthesized under microwave irradiation. One-dimensional （1D） microwires and 2D microdisks of DMF-HPPO have been selectively prepared by controlling the solution polarity. XRD results revealed the two microcrystals exhibit distinct diffraction patterns, which indicates that they have belonged to different crystalline nature. The microcrystals demonstrate shape-dependent amplified spontaneous emissions （ASE） that the emission of ID microwire is central around 618 nm and the 2D microdisk emits fluorescence at 650 nm. This result reveals the controlled synthesis of two microcrystals and their consequent multicolor amplified spontaneous emission, providing considerable promise for the development and application of new opto-electronic devices.

Because of the environmental and socioeconomic impacts of anthropogenic sea level rise （SLR）, it is very important to understand the processes leading to past and present SLRs towards more reliable future SLR projections. A regional ocean general circulation model （ROGCM）, with a grid refinement in the Bohai, Yellow, and East China Seas （BYECSs）, was set up to project SLR induced by the ocean dynamic change in the 21st century. The model does not consider the contributions from ice sheets and glacier melting. Data of all forcing terms required in the model came from the simulation of the Community Climate System Model version 3.0 （CCSM3） under the International Panel on Climate Change （IPCC）-A2 scenario. Simulation results show that at the end of the 21st century, the sea level in the BYECSs will rise about 0.12 to 0.20 m. The SLR in the BYECSs during the 21st century is mainly caused by the ocean mass redistribution due to the ocean dynamic change of the Pacific Ocean, which means that water in the Pacific Ocean tends to move to the continental shelves of the BYECSs, although the local steric sea level change is another factor.
