Effects of soil salinization and noncapillary porosity on the biomass forming and ecological dominance of leymus chinensis community .

土壤盐碱化程度及非毛管孔隙度对羊草群落生物量及优势度的影响。

This image , which shows the porosity of the rock , and the channels between the pores , is then subject to a computer analysis that reveals how easily hydrocarbons will flow through it under pressure-and thus the likely productivity of a well dug at that site .

然后将能够显示岩石孔隙度和岩石内部毛孔间通道的图像用计算机分析，结果会显示在有压力情况下碳氢化合物在岩石块内部流动的容易程度从而得知样品来源之处那口钻探井的可能产量。

Commonly the dolomite crytals form a framework with evenly distributed porosity .

通常白云石晶体构成格架，它有均匀分布的孔隙。

Different porosity reading on the neutron porosity log for the same formation due to gas in the pore space .

由于孔隙空间存在着气体，同一地层的中子孔隙度测井和密度孔隙度读数不同。

However , in the vicinity of tourism passage , some physical properties have slightly changed which makes porosity of soil narrowed down , which is considered as the negative influence brought up by the tourism on soil .

但在旅游通道旁侧旅游活动使土壤孔隙度变小,对保持土壤水文结构功能有消极影响。
