沥青基石墨纤维中的夹杂物

用透射电子显微镜观察各向同性沥青基石墨纤维中的夹杂物,大多数夹杂物呈鞋形、椭圆形、圆形或纺锤形。所观察到的夹杂物部具有明显的层状结构。而这种结构是由夹杂物内部的片状石墨晶体平行堆叠形成的。这些片状石墨在取向上都与纤维轴相垂直。在夹杂物内部还发现了垂直于纤维轴的裂纹。     

Accumulation process and model for the Ordovician buried hill reservoir in the western Lunnan area, the Tarim Basin

The Ordovician buried hill reservoir in the western Lunnan area, a type of dissolved fracture and cavernous reservoir, is mainly composed of heavy oil. The oil is the mixture sourcing from the Middle-Lower Cambrian and Middle-Lower Ordovician, with three stages of pool forming process： （1） the destruction and parallel migration/accumulation during the late Caledonian to early Hercynian; （2） the oil and gas accumulation during the late Hercynian characterized by adjustment upward along faults and parallel migration/accumulation; （3） the formation of heavy oil during the latest Hercynian. The Ordovician buried hill reservoir is affected by the diffusion of light oil and gas but had no hydrocarbon charging during the late Yanshan period to Himalayan period, but in this period, formed the association of heavy oil and dissolved gas cracked from crude oil with dry coefficient of 0.91-0.96. The study on accumulation process of the Ordovician buried hill reservoir has important implications for the exploration potential of early oil and gas accumulation in the cratonic area of the Tarim Basin.

K6合金铸造叶片质量分析

应用金相显微镜和扫描电镜以及Ｘ射线能谱分析了Ｋ６合金铸造叶片的质量问题。结果表明：Ｋ６合金铸造叶片报废的主要原因在于非金属夹杂物在浇注成型时混入合金叶片中造成的，因此需要严格控制Ｋ６母合金质量和选择合理的重熔浇注工艺参数。     

联苯/环糊精包合物的药物释放研究

研究了联苯/环糊精(BP/CD)包合物的联苯释放过程。通过比较联苯和BP/CD的热重曲线,发现BP/CD对联苯的稳定作用,对BP/CD及BP/CD填充聚乙烯膜的联苯释放过程进行比较,发现在较薄的填充薄膜中,BP的释放过程是以BP从CD中的解离为控制步骤。此外,还推导了BP/CD的释放反应动力学方程,并计算了活化能。     

轴对称异质体引起波散射问题的边界元解

通过将全空间内轴对称异质体边界载荷沿周向作Ｆｏｕｒｉｅｒ级数展开，然后利用边界元法在母线方向求解边界积分方程，使弹性波散射问题的维数由三维降到一维．该方法充分利用旋转体轴对称的几何特点，采用环壳单元使计算量较普通边界元法更小，并且收敛速度较其他边界元法更快．

Biomarkers in fluid inclusions of polymetallic deposit of Qixiashan, Nanjing

Conclusions Organic fluid involved in Pb-Zn mineralization in the polymetallic deposit of Qixiashan probably derives from bacteria and algae, and is similar to that of the mature crude oil system. Part of lead and zinc in fluids can be transported by organic complexes, while their precipitation is caused by organic reduction. Biomarkers in ores can indicate the source of organic matter in fluids, but organic matter in inclusions must be studied to ascertain organic metallogenesis because of the EOM difference between ores and inclusions. The host strata of Upper Carboniferous (C2) and Lower Permian (PI) in Qixiashan deposit are both oil-bearing in the region. Identification of organic fluid and its biomarkers in the deposit provides significant information for further studies on the relationship between ore deposits and oil pools in the region.
