Cone index penetrometer is a special apparatus widely used for assessing soil compaction in agriculture. 摘要圓錐指數儀是農業(yè)上用于測量土壤壓實(shí)度的專(zhuān)用設備。
They forked up as much of the soil possible,easing compaction. 他們盡可能的挖出泥土,減輕土壤夯實(shí)程度。
The residual porosity indicates the compaction state of the formations. 而剩余孔隙度又反映了地層的壓實(shí)狀態(tài)。
Some turf areas stay saturated following rain while others dry out quickly, and other areas need more soak time to allow the water to penetrate through densely compacted soil. 一些草坪地區逗留飽和以下雨,而其他干燥迅速,和其他領(lǐng)域需要更多的浸泡時(shí)間,讓水滲透,透過(guò)密集的壓實(shí)土壤。
