athe coefficient of volume compressibility is the slope of the volumetric water content function in the positive pore pressure range and in physical terms it describes how much a saturated soil volume will swell or shrink for a given change in pore pressure 容量压缩性系数是容量水含量作用的倾斜在...

(m) is the indirectly measured osmotic head of the saturated soil; [theta](h) is the directly measured unsaturated volumetric water content as a function of the matric head, h (m); and [h.sub.o](h) is the osmotic head of the unsaturated soil expressed in terms of the matric head (...
This paper presents an empirical equation to predict the cohesive component in the shear strength of unsaturated residual soils as an exponential function of volumetric water content. The formulation originated from a multiple linear-regression analysis for data sets obtained from shear tests using ...
In this condition, the amount of fluid in each position of the porous material is a function of the distance between the desired position and the fluid movement starting point as well as the elapsed time. In this research, a novel methodology is proposed for estimating the volumetric water ...
Thermal Properties of Soils as affected by Density and Water Content Thermal properties dictate the storage and movement of heat in soils and as such influence the temperature and heat flux in soils as a function of time and... NH Abu-Hamdeh - 《Biosystems Engineering》 被引量: 309发表: 20...
Further, a shrinkage and re-expansion function of volumetrically printed SS structures was observed. The shrinkage property of volumetrically printed structures was induced by immersion in 100% ethanol solution for a least 2 h; during the shrinking process, the water molecules were replaced by th...
1. The Volumetric Karl Fischer Titration is suitable for determination of water content down to 1% of water. The sample is dissolved in Karl Fischer Solvent (usually methanol based) and the iodine is added as a part of a KF Reagent con...
Determination method:Karl fischer volumetric method;Moisture content determination range:0.001%-100% (water phase content);Accuracy of titration control:0.001ml(20ml high precision burette);Measurement resolution:1ppm;Polarization voltage adjustable rang
The Schwarz-Wang model was chosen in preference to the others because it gives both the real and the imaginary parts of the complex relative permittivity [Epsilon](W,f) of soil-water mixtures as a function of frequency f and of the volumetric moisture content of the soil W. Soil moisture ...
