The sequences of fluvial terraces in the Yazi Spring Stream are signs of the stepwise uplift of the Kunlun Mountains in the northern part of the Tibetan Plateau since the Late Pleistocene. Geomorphic and sedimentary features of the terraces reveal that they have resulted from the phased tectonic uplift and the consequent river incision in the northern plateau. Using the method of Single-aliquot Regenerative-dose (SAR) Protocol and Radiocarbon 14C dating, the deposit ages of three-grade terraces were ob- tained, which are 57.5, 12.8 and 5.7 kaBP, respectively. The features and ages of terraces reveal that the incision rate of the stream accelerated at the beginning of the Holocene. The incision rate changed suddenly at 12.8 KaBP, from 0.43±0.07 mm/a to 1.59±0.55 mm/a. This implicates that uplift of the Kunlun Mountains is intensive at the first onset of the Holo- cene, corresponding to the obvious change of slip-rate on the Altyn Tagh Fault. But its uplift rate is much lower than that of the latter, which suggests that growth of the northern mar- gin of the Tibetan Plateau is stronger than its interior.

研究结果表明 ,V .natriegens可以利用葡萄糖、果糖、以及糖蜜为碳源合成聚羟基丁酸 [Poly(3HB) ];当以糖蜜为碳源时 ,积累的Poly(3HB)达到细胞干重的 2 8.4%。实验结果还表明 ,Poly(3HB)的积累滞后于细胞生长 ,在培养前加入过量的碳源 ,不仅没有Poly(3HB)积累 ,还抑制细胞的生长。测定了与Poly(3HB)合成相关的PHA聚合酶、β 酮硫解酶和乙酰乙酰CoA还原酶的活性。结果表明 ,伴随Poly(3HB)合成 ,PHA聚合酶活性从无到有 ,β 酮硫解酶活性提高了 10倍以上。进一步通过利用脂肪酸合成代谢抑制物———浅蓝菌素 (cerulenin) ,研究了脂肪酸从头合成途径与Poly(3HB)合成途径的关系 ,发现浅蓝菌素能够明显降低细胞Poly(3HB)的累积。根据以上结果 ,推测在V .natriegens中可能存在有两条代谢途径参与Poly(3HB)

Thermal history of the Sichuan basin is reconstructed based on vitrinite reflectance from boreholes in the basin using a paleo-heat flow *** results show that the Sichuan basin experienced a relatively low heat flow period in the Early Paleozoic,and an elevated paleo-heat flow,ranging 60-80 mW/m with a maximum as high as 100 mW/m around 259 Ma,from the beginning of the Late Paleozoic to the end of the early Permian,and a decreased paleo-heat flow from the late Permian to the late Triassic,and then maintained nearly stable to the *** Late Paleozoic paleo-heat flow was quite high where there were extensive Emeishan flood basalts or concealed basalts which erupted between the early and the late Permian,such as the southwestern and northeastern areas of the Sichuan *** to the distribution of paleo-heat flow,it can be inferred that,the northeastern Sichuan basin was also influenced by the Emeishan magmatic activity during the Dongwu movement though there was lack of Emeishan flood *** addition,the results of thermal history reconstruction of the Sichuan basin provide paleogeothermal evidence for the existence and onset of the Emaishan mantle plume.

The results suggest that there are both similarities and differences between chinese and the western beliefs about liars and lying *** causalities of the similarities and discrepancies are provided from social developmental and evolutionary psychological perspectives.

An ultrahigh pressure ductile shear melange crops out on the beach of Yangkou Bay near Qingdao City. The melange is composed of weakly deformed blocks in a highly ductilly flow mylonites. Ultrahigh pressure meta-morphic (UHPM) tectonite includes strongly deformed ec-logite and mylonitized eclogite. Coesite occurs in the tectonite as both interstitial mineral and inclusions in garnet and omphacite, indicating that the deformation took place in the stability field of coesite (800-850°C, >30 GPa) in the upper mantle. Coesite is rounded or short prismatic grains with undulatory extinction, and often fractured, suggesting brittle deformation. Garnet is also characterized by brittle fractures and sometimes necked and slightly elongated. Omphacite is elongated, with long axis preferred orientation. Undulatory extinction, subgrains and dynamically recrystallized grains suggest plastic flow of omphacite. Ultrahigh pressure meta-morphic tectonite was probably formed in the ductile shear zone during the early
