以地球系统科学的视角研究大气二氧化碳含量对地球宜居性的扰动是当今最为前沿的地球科学问题之一。大气二氧化碳浓度受控于火山、地幔排气、大陆风化和反风化等过程。大陆风化和高温热液作用是海洋锂的主要来源,而反风化作用则是海洋锂储库的汇。风化过程、热液蚀变和反风化过程中,锂同位素发生不同程度的分馏,而这些源和汇过程中的锂通量及其同位素的分馏共同控制了海水的锂同位素组成。因此,海水锂同位素组成可用于地表环境深时碳循环的示踪。近年来,通过海洋碳酸盐岩的锂同位素、87Sr/86Sr比值及碳同位素等指标的联用,来示踪新生代和前寒武纪等关键地质时期的构造—气候—风化共同影响的碳循环过程是研究热点。文章梳理了现代海洋锂元素循环的源汇过程,重新限定大陆风化和高温热液输入海洋的锂同位素组成。并在此基础上,分析了目前海水锂同位素质量平衡模型中的不确定性,探讨了海水锂同位素记录在示踪深时碳循环方面的应用和局限性,为锂元素及其同位素指标的应用和全球锂循环研究的深入提供参考。

为了探究水在纳米管中的非稳态流动特征和水在纳米级别多孔介质页岩中的非稳态渗流特征,将非稳态理论与纳米尺度孔隙中水传输的机理相结合,提出了纳米管中水的非稳态流量增强模型和混合润湿多孔介质中水的非稳态表观液体渗透率(ALP)模型,分析了管径和润湿性对单纳米管中水的流动及流动达到稳定时间的影响,孔径非均质分布对纳米多孔介质的ALP以及渗流达到稳定时间的影响。结果表明,单纳米管中水流达到稳定状态所需时间与润湿性有很大的关系;亲水条件下,水流达到稳定时间较短,接触角对稳定时间的影响很小;但在疏水条件下,水流达到稳定时间成倍增长,接触角对稳定时间的影响显著增大。另外,多孔介质平均孔径对ALP稳定时间的影响相对于偏差系数更为敏感。在非稳态阶段,润湿性、孔径非均质分布对ALP的影响不显著,当水流逐渐稳定,上述参数对ALP的影响逐渐显著。非稳态ALP模型可以同时描述水流非稳态和稳态两个阶段的流动特征,是对稳态ALP的一种重要补充。
