AFT data of granitoid and metamorphic samples from the Dabieshan orogen have an age range between 96.4 Ma and 41.9 Ma coupled with confined track lengths of 11.5—14.0 μm, reflecting the cooling time of rocks differentially through the 100℃± isotherm. The Juras- sic-Eogene sediments from the North Huaiyang and Hefei basin, however, yield their AFT ages of 128.8—62.0 Ma with mean track lengths of 8.6—11.9 μm, recording a complicated thermal de- velopment of the basin. These AFT data structurally allowing the coupling between the orogen and the basin are to a great extent considered as the result from the control of NNE-trending regional tectonics. It took place approximately at 95—90 Ma that the orogen developed with an abrupt shift from the doming extension to the differential transtension, which is assumed to be related with the changes of the convergence between the Western pacific and Eurasia plates. The differentially sinistral strike-slipp.ng from the transtension between Tanlu and Shang- cheng-Macheng faults brought the doming extension of the orogen shrunk sharply in Late Cre- taceous. In Eogene, the full-grown transtension that dominated in East Asia was caused mainly by a rapid decrease of the rates of the Western pacific convergence, which can be therefore re- garded as a major mechanism creating the zonal anomalies of 60—40 Ma in the orogen. The thermal anomaly of 70—40 Ma zonally along the Tanlu fault cooled more slowly than the anomaly of 60—55 Ma zoning along the Shangcheng-Macheng fault, but the 60—40 Ma anomaly trending E-W in hinterlands of the orogen seems to be relicts of the doming extension as a result of inten- sive rebuilding by the transtension. In addition, the orogen was also reactivated by the far-field effect from India-Asia collision in Eogene, where major NWW-trending faults played an important role in facilitating such far-field tectonic transferring. In Oligocene to Miocene, the Dabieshan orogen remained a few thermal disturbances with

分化型甲状腺癌(DTC)大多进展缓慢,经手术、促甲状腺素抑制治疗和(或)放射性碘(RAI)等规范化治疗后总体预后好,但仍有部分患者治疗后出现复发或远处转移,并可能在自然病程或治疗过程中丧失摄碘能力,不能从后续RAI治疗中获益,成为碘难治性分化型甲状腺癌(RAIR-DTC)。RAIR-DTC患者可选择的治疗方法有限,且效果欠佳。近年来,随着对RAIR-DTC分子机制研究的不断深入,诱导再分化联合RAI治疗在RAIR-DTC中展现出一定的应用前景。本文综述了信号通路抑制剂、组蛋白去乙酰化酶抑制剂(HDACi)、DNA甲基化酶抑制剂、维甲酸类药物及过氧化物酶体增殖物激活受体(ppAR)激动剂在RAIR-DTC诱导再分化治疗中的进展。

Corex is an alternative ironmaking process and raceway is one of the important areas to maintain the stability of the furnace. The raceway parameters are well established for blast furnace operation. But for Corex process,it has not yet been established and optimized. Thus,a mathematical model was developed to determine various raceway parameters such as RAFT （raceway adiabatic flame temperature）,tuyere gas velocity and kinetic energy. The model provides an idea about the raceway geometry,zone temperature and kinetic energy accumulated in tuyere gas. Besides,all the raceway parameters have been analyzed to find out their effects on the Corex process. It is found that RAFT influences the gasification reaction kinetics and higher RAFT generates more CO in reduction gas,which improves the metallisation degree of the DRI in shaft. It is also found that increased gas velocity and kinetic energy generate more fines and demand more coke to maintain char bed permeability. High coke rate increases the production cost and lowers the production of hot metal.

In this work thermal conduction in one-dimensional （1D） chains of anharmonic oscillators are studied using computer simulation. The temperature profile, heat flux and thermal conductivity are investigated for chain length N = 100, 200, 400, 800 and 1600. In the computer simulation anharmonicity is introduced due to Fermi-pasta- U1am-β （FpU-β） model For substrate interaction, an onsite potential due to Frenkel-Kontorova （FK） model has been used. Numerical simulations demonstrate that temperature gradient scales behave as N-1 linearly with the relation J = 0.1765/N. For the thermal conductivity K, KN to N obey the linear relation of the type KN = 0.8805N. It is shown that thermal transport is dependent on phonon-phonon interaction as web as phonon-lattice interaction. The thermal conductivity increases linearly with increase inanharmonicity and predicts relation κ =0.133 ＋ 0.804β. It is also concluded that for higher value of the strength of the onsite potential system tends to a thermal insulator.
