The electrical conductivity of slags is an important factor in the design of electric smelting furnaces. Although there are
many experimental studies on this subject, as yet there are no quantitative correlations of conductivity to slag composition
and temperature. The objective of this work was to develop such correlations, on the basis of the experimental data by various
other authors. The results show that in the concentration range of industrial-type SiO2-CaO-MgO-MnO slags the slag conductivity can be expressed as a linear function of the molar concentrations of the basic oxides;
in the concentration range of industrial nonferrous slags, where the iron oxide content is usually over 20 pct, the slag conductivity
can be expressed as an exponential function of the molar concentrations of the iron and basic oxides. The effect of temperature
on slag conductivity, in the industrial range of interest, can be accounted for by means of an Arrhenius-type of equation. 相似文献

Reviews the book, From neuropsychology to mental structure by Tim Shallice (see record 1989-97122-000). The basic question that the book addresses is "what can be learned about normal function from impaired behaviour?" The author approaches this question in two ways. First, he assumes that cognitive processing is organized into basic processing elements, much like Fodor's modules. The goal is to determine how the modules function together to underlie cognitive processes. Second, Shallice asks how neuropsychological data provide inferences about the nature of the modules. Overall, I liked this book, even if I cannot easily identify with the top-down approach to studying brain function. Nonetheless, this is a volume that will force psychologists of all stripes to think about questions surrounding the study of cognition and brain function. Indeed, one can seriously ask the question of whether cognitive neuropsychology is a natural evolution of Hebb's neuropsychology as opposed to a new and divergent species that will fill a different niche.
