The cultivator shanks, instead of the plough, allow a decompaction, superficial and deep explosion of the soil.
联合整地机的深送齿，用来代替犁，它使得土壤表层振松，深度打碎。

The main problem of decompaction correction is how to found a reliable porosity depth function or density depth function which expresses the compaction process of clastic rock.
碎屑岩层的去压实校正的主要问题是建立一个能正确反映岩层压实规律的孔隙度深度函数或密度深度函数。

A function found on the data of porosity depth or density depth from a given layer in one well or poly wells could be more reliable so that it can figure out a satisfying decompaction thickness.
