Important spore and angiospermae pollen fossils such as Asterisporites,Cranwellia,Xinjiangpollis,Beaupreaidites and Quantonenpollenites have been obtained from the the upper part of the Member 4 of Quantou formation. They are Late Cretaceous in age. The reasonable geologic time of the upper Quantou formation may be later than Cenomanian deduced by the age of the upwards spore and angiospermae pollen fossils and the palynological assemblages.

Methods S. epidermidis atlE gene expression level at different phases was detected by RT-PCR, and the accumulation of extracellular DNA at different phases was assessed by spectrophotometric measurements of light absorbance by DNA; DNase Ⅰ was used to study the function of extracellular DNA in biofilm formation and primary attachment. The effects of atlE gene deletion on initial adherent capacity, biofilm formation and extracellular DNA release were studied by construction of atlE deletion mutant via homologous recombination.

This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.
以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄,使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高,从而易导致CA膜形成双连续结构;温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近,均相区减小;ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制,而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。
