soil swelling

基本解釋

The results showed that the content of clay particles was significantly correlated with soil swelling rate.
結果表明：土壤粘粒含量與土壤膨脹率呈顯著正相關；
The content of soil organic matter affected soil swelling rate remarkably when soil texture was not obviously different.
有機質含量在質地差別不明顯情況下，對土壤膨脹率也有極顯著的作用與影響；
Soil swelling-shrinkage is related to change in soil volume with water content in the process of soil drying and wetting.
土壤脹縮是土壤在乾燥、溼潤交替變化過程中所表現(xiàn)出的土壤容積隨含水量改變的關系。
