We discuss the methodological aspects of the problem of the choice of the parameters intended for the description of local structure of condensed matter. The commonly used approaches are critically analyzed. The main difficulty reflects the lack of well-defined concept of degree of similarity of fluctuating structures. Consequently, some conclusions of the analysis of type of local order in “computer” model liquids are shown to be meaningless. We introduce the parameters -structural invariants- which are free from these difficulties.
