粒度参数 meaning in English
size parameter
Examples
- Contrast between experimental result and geological research from drilling data of 14 wells shows that the coincidence of sandbody compose and granularity reaches 73 % , that of sand layer thickness distubution 62 % 81 % , and that of sedimentary microfaces distribution 58 %
实验结果与油田地质研究( 14口井资料)对比表明，砂体组成及粒度参数的符合率达73 ，砂层厚度分布的符合率达62 81 ，沉积微相展布的符合率达58 。 - 3 . at the vertical direction of the section , the grain - size distributional coarse and fine rhythms vary very pronouncedly with the alternation of sedimentary facies , which is clearly shown not only in the grain - size percentage in this section but also in the response from different grain - size parameters
在剖面的垂直方向，粒度的粗细韵律分布随沉积相的变化非常明显。这不仅在剖面上粒度的百分含量可以清楚地反映出来，且各个粒度参数也同样具有显著响应。 - The general characteristics of the grain - size distribution of different sedimentary facies , es pecially the variations of the parameters mz ( mean particle diameter ) and o ( standard deviation ) clearly show that the fluvio - lacustrine facies and palaeosols usually become finer in particles and worse in sorting than the aeolian sands
该剖面不同沉积相粒度的一般分布特征尤其是粒度参数? mz 、的变化明显表现出，河湖相或古土壤通常要较风成砂颗粒细化，分选相对较差。 - It indicats that the fluvial sedimentary sequence of the flood plain of weihe river in this region is rather complete and continuous . the grain - size analysis carried out in laboratory has revealed the characteristics of the changes of weihe river during last 1300 years . based on multi - disciplinary analyses , including landform characteristics , grain - size and documents datum , the paper has attained the following important conclusions
分析了渭河三个河流沉积物剖面的粒度组成特征，剖面各层粒度分布特征，剖面粒度参数md 、 mz 、 、 sk 、 kg的变化，剖面粒度特征值- 5 、 16 、 25 、 50 、 75 、 84 、 95的跳动，并将三个剖面的粒度特征作了对比。
