Evaluation of energy-dispersive x-ray spectra with the aid of expert systems

Abstract Two recently developed Expert systems in the field of x-ray fluorescence are discussed. The first deals with the qualitative interpretation of x-ray spectra; it is characterized by a large knowledge base and a relatively small data base, both of which are of uniform structure. The second contains knowledge on quantitative spectrum evaluation and so has a much larger data base; its knowledge base is much smaller (at present), but contains several different types of rules.
