新疆阿克提什坎金-多金属矿床微量元素地球化学

系统地研究了新疆阿尔泰诺尔特地区阿克提什坎金－多金属矿床的微量元素组成特征,并应用Ｇｒａｎｔ等位线方法讨论了热液蚀变作用过程中微量元素的行为。认为在热液蚀变作用过程中,微量元素尤其是Ａｕ、Ａｓ等,活动强烈,围岩为成矿提供了部分物质来源。文章还进行了质量迁移的定量计算。

High-precision timing of the Quaternary standard samples with thermal ionization mass spectrometry (TIMS) U-series method

Two national stalagmite standard (GBW04412, GBW04413) and one international coral standard (RKM_4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of ( 234 U/ 238 U) act , ( 230 Th/ 234 U) act and age are all consistent in error range with the standard values obtained by using α spectrometry.     

Osmium isotope determination on mantle-derived peridotite xenoliths from Panshishan with N-TIMS

The¹⁸⁷Os/¹⁸⁸Os ratios of spinel lherzolite xenoliths from Panshishan determined with N-TIMS are lower than that of the primitive mantle, which shows depleted mantle characteristics. Their positive correlation with Al₂O₃/MgO suggests that the geochemical behavior of trace elements Re and Os is similar to that of Al₂O₃ and MgO respectively during the magmatic evolution and Re-Os isotopic system is largely immune to mantle metasomatism. A model age of 2.8–3.4 Ga obtained by¹⁸⁷Os/¹⁸⁸Os-Al₂O₃/ MgO correlation might represent the homogeneous age of the mantle lithosphere beneath the area.     

Determination of tectonic background for sedimentary basin from sandstone geochemistry

The chemical composition of sedimentary rocks is mainly controlled by source rocks. Through examining chemical composition of terrigenous rocks, the tectonic evolution of a sedimentary basin can be modeled. The Turpan Basin belongs to a continental sedimentary basin and its source rocks are derived from the upper continental crust.

在现有徐主计算方法的基础上,提出了适用于Ｄａｒｗｉｎ模型的徐变计算方法。给出了混凝土未开裂和开裂时的徐变计算公式。实际工程算例表明,本文提出的方法是合理的。     

氧同位素：追踪陆架海沿岸水团变化的良好标志

对于陆架海而言除了冰体积效应,温度效应外,还有由于大陆淡水注入引起的,使δ＾１８Ｏ值负向偏移的效应,而且在低海平面时期,当沿岸水团盛行时,这种效应起主导作用。笔者将这种效应从广州的盐度效应中分离出来,称为陆架海的负值效应。     

水平多孔窗内蒸发现象与制冷效应的二维数值模拟

从连续介质力学的观点出发,建立了描述非饱和多孔介质内部热质传递现象的二维稳态模型.并用此模型对水平多孔窗的传热传质过程进行了数值模拟,得到了不同运行工况下的床内各量的场分布及其蒸发制冷量分布,从而揭示了环境参数与多孔窗内部热质传递及其换热性能之间的内在联系.
