The Triassic Jialingjiang Formation and Leikoupo Formation are characterized by thick salt layers. Three tectono-stratigraphic sequences can be identified according to detachment layers of Lower-Middle Triassic salt beds in the northern Sichuan Basin, i.e. the sub-salt sequence composed of Sinian to the Lower Triassic Feixianguan Formation, the salt sequence of the Lower Triassic Jialingjiang Formation and Mid-Triassic Leikoupou Formation, and the supra-salt sequence composed of continental clastics of the Upper-Triassic Xujiahe Formation, Jurassic and Cretaceous. A series of specific structural styles, such as intensively deformed belt of basement-involved imbricated thrust belt, basement-involved and salt-detached superimposed deformed belt, buried salt-related detached belt, duplex, piling triangle zone and pop-up, developed in the northern Sichuan Basin. The relatively thin salt beds, associated with the structural deformation of the northern Sichuan Basin, might act as a large decollement layer. The deformation mechanisms in the northern Sichuan Basin included regional compression and shortening, plastic flow and detachment, tectonic upwelling and erosion, gravitational sliding and spreading. The source rocks in the northern Sichuan Basin are strata underlying the salt layer, such as the Cambrian, Silurian and Permian. The structural deformation related to the Triassic salt controlled the styles of traps for hydrocarbon. The formation and development of hydrocarbon traps in the northern Sichuan Basin might have a bearing upon the Lower-Middle Triassic salt sequences which were favorable to the hydrocarbon accumulation and preservation. The salt layers in the Lower-Middle Triassic formed the main cap rocks and are favorable for the accumulation and preservation of hydrocarbon.

In light of the principle of sequence stratigraphy, detailed analysis of depositional sequences and systematical carbon isotope measurements were done for the Triticites zone of the typical Late Carboniferous section in the Dushan area of southern Guizhou. Two sequences and seventeen parasequences, which can be correlated with the two sequences and seventeen subsequences in the North American Midcontinent, are distinguished in the Gzhelian, which provides convincing evidence of the global synchroneity of the depositional records. The internal relations between carbon isotope evolution and eustasy were studied and the evolutionary characteristics of carbon isotopes in depositional sequences have been summarized.

To screen obesity-related protein biomarkers of young men using differential proteomic method and OffGel electrophoresis.Ten male obese volunteers with the age of 18 - 44 years were selected. The control group was matched with the ratio of 1:1 considering the factors of age and gender etc. Two milliliter venous blood was collected after 8 hours fasting. Albumin and IgG were removed from the plasma samples with highly specific immune-affinity method. Then the peptide-mixed samples were separated by pI with OffGel electrophoresis after solution digestion. Further separation and identification were performed by Nano HPLC-Chip-MS/MS system. The different proteins between the two groups were compared.Overall, 332 and 301 proteins were identified in the obesity and control groups, respectively. There were 43 proteins with significant differences between the two groups, 17 of which were in the control group and 26 in the obesity group. Protein function annotation results showed that the level of adiponectin was lower while the level of C-reaction protein and three other phosphatases were higher in the obesity group compared with the control group.Adiponectin, C-reaction protein and three phosphatases were closely related to obesity of young men.

We calculate the evolution of a large and a medium mass star through the core H and He burning stages using the most recent OPAL opacities, both with and without a moderate amount of convective overshooting. The inclusion of the overshooting produces appreciable changes in the evolutionary track on the H-R diagram, in the durations of the central H and He burning phases and in the location of the H burning shell. In the medium mass case, the central temperature-density depends sensitively on whether or not overshooting is included.

In order to predict the life of engineering structures, it is necessary to investigate the strain distribution in notched members. In general, the Bauschinger Effect of materials under cyclic loading is not negligible, and so the anisotropic hardening model has been suggested. From the comparison between the calculated and experimental results in this paper, we can see that even the linear kinematic hardening model is quite suitable for strain analysis under cyclic loading.
