The second stage, from 200 ℃ to about 400 ℃, is due to the change of the type of dislocations with annealing temperature. 第二阶段从200℃至400℃左右,在这个阶段中,随着退火温度的上升,位错类型从平均柏氏矢量较大的位错改变成平均柏氏矢量较小的位错;
Then the second stage used the simulation annealing algorithm to use the first stage the preliminary optimal solution to carry on the solution take the user service degree of satisfaction as the objective function mathematical model. 然后第二阶段采用了模拟退火算法使用第一阶段的初步最优解对以用户服务满意度为目标函数的数学模型进行求解。
