| 英文摘要 | Based on the quantum molecular dynamics model, the dynamical behaviors of the Liquid-gas phase transition in nuclei are investigated. In order to explore the characters of the Liquid-gas phase transition in the vicinity of the "critical point", the Maximum Lyapunov exponent (MLE) is employed and the method of calculation of the MLE is developed. The dependence of the mass distribution of fragments, density fluctuation and the MLE on temperature has been studied for nuclear systems Sn-124 and Pb-208. As the main results, We have found that for heavy nuclear systems the MLE and the density fluctuation reach the maximum values at the same temperature, in which the maximum liquid-gas coexistence region is also found from the mass distribution of fragments. |
