Abstract
We divide the particle generating sources in nucleon-nucleon collisions into two parts： binary collisions and leading particles， and present the analytical relation between chargedparticle pseudorapidity distributions and incident energy. On the basis of this work， we classify the particle generating sources in nucleus-nucleus collisions into three parts：binary collisions，leading particles and spectators，and formulate the chargedparticle pseudorapidity distributions as the function of incident energy and impact parameter. We then analyze with the model the experimental measurements in d+Au collisions at sNN=200 GeV. The theoretical results are well consistent with experimental data.
