Columnar joint, microfissure and gently dipping structural surface are the three fundamental factors which lead to the small deformation modulus of basaltic mass. 白鹤滩柱状节理玄武岩中发育的柱状节理、微裂隙及缓倾角结构面是导致岩体变形模量较低的主要因素;
The major three pore assembly types are shown below: microfissure, microfissure_pore and pore, and are dominated by the first two types. 孔隙组合类型有微裂缝型、微裂缝-孔隙型和孔隙型3种,并以前两种类型为主;
The forming of the Au-bearing quartz vein mainly underwent 4 stages ( Emplacement of rock body and hydrothermal forming, forming of host structure and quartz vein filling, forming of microfissure and mineral enrichment). 含金石英脉的形成主要经历了岩体侵位及热液形成、容矿构造形成及石英脉充填、微细裂隙形成及富集成矿等4个阶段。
This paper mainly discussed several methods used to decide microfissure, its distribution and reservoir-forming mechanism in abnormal pressure zone in mudstone. 主要论述了泥岩异常超压带内微裂隙的几种确定方法、分布及成藏机制的研究。
The results show that higher temperature, lower velocity and lesser microstructure will reduce microfissure and obtain purer diamond film, so the fracture strength of the diamond film is higher. 结果表明,较高的生长温度,较低的生长速率,较小的晶粒尺寸,较少的微观缺陷,较高的金刚石纯度,可以提高CVD金刚石的断裂强度。
By the theory of Griffith` s microfissure, the factors which affect CVD diamond fracture strength is presented. 按照Griffith微裂纹理论,讨论了影响CVD金刚石断裂强度的因素。
With the application of the microfissure development theory, this paper also analyzes the whole procedure of the experiment of the SFRC in both way of macro-process and micro-mechanism. 应用微裂缝开展理论,对钢纤维混凝土环向受拉全过程作了宏观过程和微观机理的分析;
On the other hand, this situation will increase the non-homogeneous difference between the microfissure-developing and non-microfissure-developing zones, leading to the significant heterogeneity in distribution area of gas reservoirs and enrichment of natural gas in the study area. 但另一方面,这种情况又会加重裂缝发育区和非发育区间的非均质差异,导致气藏分布面积与天然气富集程度在研究区存在明显的非均质性。
These two categories of reservoirs has such strong points as good configuration of pores and microfissure, good performance of reservoir and seepage, and a sizable gas-bearing area. However, their heterogeneity should be taken seriously in the process of exploration and development. 这两类储层孔隙和微裂缝匹配良好,储渗能力强,含气面积大,但其非均质性应在勘探开发中予以重视。
