Sampling of heterogeneous and dynamic material systems : theories of heterogeneity, sampling, and homogenizing /
Although sampling errors inevitably lead to analytical errors, the importance of sampling is often overlooked. The main purpose of this book is to enable the reader to identify every possible source of sampling error in order to derive practical rules to (a) completely suppress avoidable errors, and...
