摘要
The method of scaled factorial moments is used to study the fluctuations offragment-size distribution based on the quantum molecular dynamics model.From thecalculation of <sup>197</sup>Au（200 MeV/nucleon）+<sup>197</sup>Au central collision system,an intermit-tent pattern of fluctuations is found.In particular,the critical behavior is preliminarilydiscussed.
