摘要：

A moment analysis in terms of bivariate distributions of global variables for two colliding nuclei at intermediate energy is presented. It is shown that the selection of the impact parameter through narrow cuts in the total transverse kinetic energy naturally modifies the true fluctuations of the fragment multiplicity distributions. This is supported by a classical simulation of a system whose equation of state resembles that of nuclear matter. An intermittent behaviour of two colliding nuclei at a beam energy around 100 MeV/nucleon and large impact parameters is suggested.
