摘要： 我们在格点规范场理论的Monte Carlo模拟中引入了一种节省时间的取样方法,研究了该方法在Z2规范群和SU(3)规范群临界点附近的行为,发现在越过一阶相变点时该方法将失效。按一定的程序,此特点可用来寻找一阶相变点。

Abstract: A fast sampling method which can afford saving much computer time was suggested.We studied the behaviour of this method near the critical points for Z2 and SU(3) gauge groups.It is found that this method will lose his effect when passes through the first order phase transition points.This character will be used to find the first order transition according to some program.
