Abstract：
Existing data of rapidity patterns of charged particles can be utilized to determinesome important types of inclusive spectra of nearby particles.Some of these types maybe used to study such open or controversal problems as the size of the cluster,thelocal conservation of charges,the effect of Bose-Einstein statistics etc.The statisticsof these patterns is in general sufficient for inclusive spectra of nearby particles in-cluding 2 to 3 parameters and variables,and insufficient for those including 4 to 5variables.In the latter case we introduce two special methods for the organization ofdata:one of them is to find various types of‘averages’over rapidity intervals of thenearby particles,and the other is to find inclusive spectra of nearby particles in theneighborhood of the maximum point.By means of these methods,some special featuresof inclusive spectra of nearby particles including 4 to 5 parameters and variables,may be significantly determined.The fragmentation model,advanced by Yang and collaborators,the one-dimen-sional version of Chew-Pignotti model with and without diffraction,and the inde-pendent cluster emission model in the form proposed by Quigg and collaborators,areused to calculate crudely the finestructures of inclusive and semi-inclusive spectra aswell as to test the sum rules and the generalized form of Feynman-Yang scaling.
