The researches are composed of twotopics,one of which is the synthesis of mesoporous metallosilicates and the other isthe interlayer expansion of zeolitic lamellar precursors by post-silylation.
本文以提高沸石分子筛催化活性中心的可接近度，改善其扩散性能，扩大沸石分子筛在处理大分子反应物方面的应用范围为目的，在含有介孔的杂原子分子筛的制备和层状分子筛层间结构改性两个方面，开展了以下四部分研究工作。
The pore types of the deep reservoir are divided into three types, namely, the primary pore, secondary pore, and mixing pore.
通过对胜利油区渤南洼陷深部储层特征的研究 ,提出了深部储层孔隙类型划分方案 ,将孔隙划分为原生孔隙、次生孔隙和混生孔隙三大类 ;将裂缝划分为构造缝、重力滑移缝、异常压力缝、成岩缝、原生缝、塑性变形面、溶蚀裂缝七大类 ,把裂缝型储层提到了与孔隙型储层同等重要的位置 ,强调了泥岩裂缝型储层的重要
Porosity may be classified according to the mode of origins (1) original and (2) induced.
按其原始形态，孔隙度可分为原生孔隙度和次生孔隙度。
The pore spaces are completely dominated by primary porosity and pores, vogs and fractures with secondary origination.
孔隙空间主要是原生孔隙及由次生原因形成的孔隙和裂缝。
Original porosity is typified by the intergranular porosity of sandstones and the intercrystalline and politic porosity of some limestones.
原生孔隙度以砂岩粒间孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。
ocks having original porosity are more uniform in their characteristics than those rocks in which a large part of the porosity is induced.
具有原生孔隙度的岩石比次生孔隙度占大部分的岩石在性质上更具有一致性。
