This paper studies the influence of technical conditions such as sintering temperature,powder partical size,forming pressure on capabilities such as totalporosity,percentage of opening and benging strength.
研究了烧结温度、粉末粒度、成形压力等工艺条件对多孔钨制品的总孔隙度、开孔率、抗弯强度等性能的影响,同时能制得总孔隙度30%以上,开孔率占总孔隙度95%以上,抗弯强度200 MPa以上的多孔钨材料制品。
The total porosity and the aerate porosity decrease after the rain while the faster available porosity and the slow available porosity increase .
降雨后土壤的总孔隙度下降，通气孔隙下降较明显，同时速效孔隙和迟效孔隙增多。
Aeration porosity is more sensitive than total and capillary porosity to reflect soil compaction degree.
与总孔隙度和毛管孔隙度相比,通气孔隙度在反映土壤压实时更为敏感。
For intergranular materials, poorly to moderately well cemented, the total porosity is approximately equal to the effective porosity.
对于由晶体构成的物质，其晶粒间含泥浆少或较少，因此总孔隙度与有效孔隙度近似相等。
For more highly cemented materials and limestones, significant difference in total porosity and effective porosity values may occur.
对于含泥浆较多的物质或石灰岩，其总孔隙度和有效孔隙度会有很大差别。
An amendment should decrease bulk density, increase total porosity, and increase water and air content.
改良剂能降低堆积密度，增加总孔隙度，增加水和空气的含量。
An amendent should decrease bulk density, increase toltal porosity, and incr ease water and air content.
改良剂能降低容重，增加总孔隙度，增加水和空气的含量。
Porosity is defined as the ratio of the void space in a rock to the bulk volume of that rock multiplied by 100 to express in percent.
孔隙度定义为岩石内的孔隙体积占岩石总体积的百分率。
The ratio of the volume of all the pores in a material to the volume of the whole.
孔隙率一材料中孔隙的总体积与整个材料的体积之间的比率
A separation, an aperture, a fissure, or a short passage in an organ or a body part.
裂孔，孔器官或身体部位中的孔隙、隙缝、裂隙或通道
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。
