heavy water content meter

In order to study soil-water characteristics of unsaturated soil slope, moisture probe and tensiometers are installed simultaneously for the soils at depths of 1, 2, 3 and 4 m at the crest of a cut slope in Hong Kong.

为了研究非饱和土边坡的土-水特征,在香港某人工边坡坡顶1,2,3,4m等不同深度同时安装了含水量计及吸力计。

The spatial variability of soil electrical conductivity and mass soil water content at the newly-reclaimed land were discussed and the rational sampling number for soil electrical conductivity and mass soil water content was given under different believable level and exactitude through the classic statistics analysis.

根据直线和网格布点法布置的150个取样点的测定资料,应用经典统计分析方法,探讨了垦荒地土壤电导率和重量含水率的空间变异性,并给出了不同置信水平及精度要求下两者的合理取样数目。
