compact layer
compacta
dense layer
strata compactum
stratum compactum
tectum
tight layers
tight zone
Examples
- The structure of artificial bone was designed according to the long bone of people , the outer was compact layer , the inner was porous spongiosa layer
仿人长干骨的结构梯度进行材料设计：外层为致密层，内层为多孔松质层。 - As the pre - evaporation time increases , the holes on the membrane surface becomes smaller and less , dense layer is becoming more evident with large and deep holes in supporting layer ; and porosity increases as well - as average hole diameter decreases
随着预蒸发时间的延长，膜表面的孔变小变少，膜的致密层越来越明显，支撑层有大而深的孔结构出现。随着预蒸发时间的延长，膜的孔隙率上升，平均孔径下降。 - Via analysis of reservoir , typical gas and tight zone , it has an obvious character that the content of cement controls reservoir property , pore texture growing , definitely effects logging responsibility and micropore controls hydrocarbon content
经对试气层段与典型气层和致密层分析，认为该区有一个明显特征：岩石胶结物的质量分数控制着储集层物性及孔隙结构的发育程度并对测井响应有一定影响，微孔喉制约着储层含气性。 - On the basis of study on structure and mass transfer , ideal model of membrane structure was built up , in which skin layer should be as thin as possible ensure resisting water to pass though membrane ; finger pore should be as long as possible in the membrane ; proper pore size ; loose sponge tissue
首先对利用相转化法制备的微孔膜形态结构进行研究，确定传导阻力较小的理想结构模型，致密层在能阻止微孔被浸润的情况下尽可能薄；指状孔在膜厚方向所占比例尽可能大；孔径大小适宜；海绵状组织结构疏松。 - Through observing the interface of porosity hap sintered at 1050 , the gradient changing of pore size was observed that was like gradient structure of bone . in the compact layer there were a few about 50 y mpores and many about 5um micropores . in the porous layer there were many about 500um pores
致密层存在少量的尺寸为50 m左右的气孔和大量的尺寸为5 m左右的微孔，这是原料中残留有机物烧失以及粉末颗粒烧结不致密形成的；多孔层存在大量的尺寸为500 m左右的大孔，这是柠檬酸造孔剂烧失形成的，在大孔之间存在一些约50 m 、 100 m的气孔。
