After roller compaction, the wetdensity of RCC would be measured by sampling from the digged pit or by nuclear densimeter.
碾压后,挖坑取样或采用核子密度水分计选点测量碾压混凝土的湿密度。

The relationship between erosion rates and shear stress was determined by the particle composition, structure, wetdensity and water content of the sediment.
沉积物的颗粒组成、结构、密度、含水率等决定了冲刷率与剪应力的变化关系。

Limestone will have the same porosity measurements, whereas a wet sandstone will cause the neutron porosity to read low and the density porosity high.
