摘要: From preliminary measurements, guidelines are given for determining whether a bulk population is well-mixed or segregated and the design of experiments to estimate sample size number. For populations, total amount collected determines degree which represented. sampling uncertainty reduced primarily by increasing number increments collected. Methods estimating Visman's constants populations discussed, along with way calculating theoretical average particle mass nonparticulate materials. An 20 g was calculated unmixed samples Athabasca oil sand. This large value, confirmed using Benedetti-Pichler equation, explains extensive required reliably bitumen water in
