Sampling Theory for Opaque Spatial Specimens
不透明空间样本的抽样理论
Summary Procedures for inferring the internal geometric structure of an opaque bounded n-dimensional set by random sectioning are discussed. General conditions are given (evidently for the first time) for the validity of the so-called “fundamental formulae” of stereology (the science of inferring spatial structure from lower dimensional data). In technical terms, a wide class of unbiased ratio estimators, based on the traces of embedded features in appropriately weighted…
