Abstract：
The dependence of entropy index μ 2 on the width and shape of multiplicity distributions are studied in detail by using Monte Carlo method and comparing with the results from NA22 experiment.It is found that the entropy index is insensitive to the shape of multiplicity distribution but decreases with the increase of the distribution width.The latter observation contradicts the usually expected role of the index,indicating that μ_q is not an appropriate parameter for measuring event-by-event fluctuation.
