摘要：

The critical behavior of the dynamical percolation model, which realizes the molecular-aggregation conception and describes the crossover between the hadronic phase and the partonic phase, is studied in detail. The critical percolation distance for this model is obtained by using the probability P-infinity of the appearance of an infinite cluster. Utilizing the finite-size scaling method the critical exponents gamma/nu and tau are extracted from the distribution of the average cluster size and cluster number density. The influences of two model related factors, i.e. the maximum bond number and the definition of the infinite cluster, on the critical behavior are found to be small.
