For exploration and potential evaluation of deep shale reservoirs with high maturity,hydrocarbon generation and pore evolution of muddy shale in deep high evolution stage were investigated by the high-temperature high-pressure simulation *** indicated that under high pressure condition,nano-scale micropores in organic matter-rich muddy shale constantly increased as rise of temperature and pressure,leading to increase of shale ***,in the high mature-overmature stage,shale porosity decreased with further increase of temperature and *** contrast to micropores,micro-scale capillary pores and megapores in shale constantly decreased as rise of simulation temperature or pressure,indicating that deep-burial reservoirs was not favorable for free-gas storage;but significant increase of micropores and surface area during this stage could make up for a loss of adsorbed natural gas in shale due to decrease of adsorption capacity which was induced by increase of temperature and pressure,thus leading to high shale gas potential in deep layers.A large number of secondary micropores were developed in the simulated samples such as pyrite and dolomite,demonstrating that shale clasts and mineral matrix could also form abundant secondary micropores during the deep evolution stage;during the evolution process,shale as hydrocarbon source rock could generate a large amount of acidic fluid which was favorable for development of secondary porosity.

In a study on the soft coral, Alcyonuim patagonicum, a new hydroxylated sterol, 24-methylenecholest-4-en-3β,6α-diol exhibiting a potent activity to murine leukemia cells (IC50 = 1 μg/mL) was isolated and synthesized. The relationship between the chemical structure and the biological activity of the hydroxylated sterols, the synthesis of 24-methylenecholest-4-en-3β,6α-diol were presented. The melting point were determined on a X4 apparatus and were uncorrected. The infrared spectra were measured with a Nicolet 205 FT-IR and Nicolet FT-360 spectrophotometer. The H NMR spectra were recorded on a Varian Unity Inova 500 NB spectrometer in CDCl3 using tetramethylsilane (TMS) as the internal standard.

Small dispersoid particles inhibit recrystallization which is critical in controlling the grain structure of many high strength low alloy steels. A general kinetic model has been developed to predict precipitation of V（C, N） in vanadium microalloyed steels with a series of carbon and nitrogen contents. The solubility product and driving force of carbonitrides precipitated in austenite as well as the interracial energy and other parameters can be evaluated to predict Nucleation rates-Temperature （NrT） and Precipitation-Time-Temperature （PTT） diagram. By using stress relaxation tests and fitting with Avrami equation, it is possible to draw PTT diagrams. The predictions of the model coincide with results of experimental investigation on V（C, N） precipitation in austenite. The nose temperature is around 850 ℃ obtained by experiment which is different from the prediction of the model and the difference is 30 ℃, and nitrogen has more effect on the shape of ＂C＂ curve of PTT diagram than carbon that makes ＂C＂ curve move leftward significantly.
