| 中文摘要 | In this paper the decay rate is obtained accurately near the crossover temperature. Because of the strong fluctuations near the crossover temperature a method called the effective Landau theory beyond the Gaussian semiclassical approximation is developed. We find that in the crossover region the transition rate of the first-order transition changes much more sharply than that of the second-order one. For both cases there is no discontinuity of transition rate for any of the order derivatives. |
