沉积岩层的韵律性或旋回性特征由岩层的岩石学性质在纵向上的（随时间的）有规律变化所决定，这些变化主要由以下方面所体现，包括：组分变化、粒度变化、颜色变化、沉积补偿强度变化、氧化还原强度变化，以及化石群性质变化等。 - Especially in carbonate formation , owing to its intricate interstice , the size , shape of cave , and the character of filling , it is almost impossible to get a all - around cognition . under the circumstance , comprehensively prediction by multi - subject method is the way to predict caves in carbonate formation
尤其对碳酸盐岩储层来说，由于孔隙空间非常复杂，缝洞的大小、形状、类型、充填物性质变化很大，用一种方法想全面了解碳酸盐岩的储层发育情况几乎是不可能的。 - This indicates that rich zn2 + and poor mn2 + ions in the colloidal solution of zns : mn2 + nps is the key to obtain highly efficient luminescence and highly quantum yields . the research on the properties of surface modification may be helpful to the widely application of nano - sized materials in the future
对纳米材料表面修饰后发光性质变化的研究有助于更加深入地认识表面和表面态的实质及其对发光的影响机制，为进一步控制纳米材料的表面，提高发光效率，创制理想高效的纳米发光材料提供基础的理论的指导，使得纳米发光材料得到更加广泛的应用。 - Took sha - zhuyu and east shore of qing - hai lake as the examples and based on the mass of field survey and soil analyse , took comparative method , we carried through the researches on the causes of the desertification , the origin of sandy desertificational land substance , the development diversification and difference of soil characteristic in process of manual and spontaneous vegetation recovery in high frigid regions and make out the taxonomy of desertificational land in high frigid region of china . the result obtained are summarized as follows : 1 . the development of the desertificational land in high frigid regions is caused by the manual and spontaneous factors
论文首次对高寒地区的砂质荒漠化土壤进行系统研究，以沙珠玉和青海湖东岸为例，通过野外考察和土壤样品室内化验，采用对比分析的研究方法，对中国高寒地区荒漠化的成因和研究区砂质荒漠化土地的形成演变，土壤发生特性、人工植被恢复和自然植被恢复过程中土壤的发育差异和性质变化进行系统研究，并用系统分类体系对研究区土壤进行类型划分，得到主要结论如下： 1 、高寒地区荒漠化的发生发展是在自然因素和人为因素共同作用下进行的，沙珠玉地区风沙土是就地产生的，青海湖东岸地区风沙土主要是由风从湖的西岸搬运而来的，两地区砂质荒漠化发展仍然十分严重。
