1河流相层序地层划分方法——以松辽盆地下白垩统扶余油层为例显示文摘以松辽盆地下白垩统泉头组扶余油层为例,探讨了河流沉积体系的层序地层分析方法。首先确定河流的成因类型和相域(微相)的构成,包括曲流河道、决口河道、决口扇、冲积平原和浅水湖泊,识别河流演化过程中由于河流冲溢形成的自旋回沉积作用和基准面变化产生的异旋回沉积作用,即基准面旋回;然后运用河流沉积学理论分析构成河流相的不同相域的形成与基准面变化的关系,识别基准面转换位置(基准面上升到下降或基准面下降到上升)的沉积学和地层学响应,从而建立等时地层对比格架。邓宏文 吴海波 王宁 Timothy A.Cross 2007石油与天然气地质2007,28,5:85

4Detecting water-protein chemical exchange in membrane- bound proteins/peptides by solid-state NMR spectroscopy--Dedicated to Professor Xiuwen Han on the occasion of her 80th birthday显示文摘Water plays an important role in many essential biological processes of membrane proteins in hydrated lipid environments.In general,the 1H polarization transfers berween water molecules and site--specific protons in proteins can be classified as coherent(via dipolar spin diffusion)and incoherent(via chemical exchange and nuclear Overhauser effect)transfers.Solid-state NMR is the technique of choice for studying such water-protein interactions in membrane-bound proteins/peptides through the detection of'H polarization transfers from water to the proteins.These polarization transfer mechanisms often exist simultaneously and are difficult to quantify individually.Here,we review water-protein polarization transfer techniques in solid state NMR with a focus on the recent progress for the direct detection of site-specific kinetic water-protein chemical exchange processes on the sub-millisecond time scale in membrane-bound proteins.The measurements of the pure chemical exchange ki-netics provide a unique opportunity to understand the role that water plays in the structure-function relationships of membrane bound species at the water-bilayer interface.In addi-tion,the perspective of chemical exchange saturation transfer(CEST)experiments in membrane-bound proteins/peptides is further discussed.Rongfu Zhang Timothy A.Cross Riqiang Fu 2021Magnetic Resonance Letters2021,1,2:0
