The optimal gas flow rate was from 25 to 50 mL/min. The solvent flux increased linearly with transmembrane pressure and the separation factor was almost constant under experimental conditions with gas sparging.

适宜的空气流量为25~50 mL/min；在气体鼓泡的情况下，溶剂透过率随操作压强线性地增加，而分离因数不受操作压强影响。

Our results show that the performance of spatial working memory task is not interfered by the object or pattern discrimination, suggesting that the cognitive functions of different association cortexes are processed in parallel.

Compared with the exchange and mutation operation in genetic algorithm ,crossover operation becomes helpless when adaptive value of most individules in demes have little difference.The algorithm falls into local solution and can't be solved by exchange. Although mutation can make it shake off local convergence and jump out of local solution, denteric mutation may destroy the produced module that is constructive to form the optimal solution.

相比遗传算法中的交换和变异操作，当种群的多数个体适应值相差不大时交叉操作就显得无能为力，算法陷入局部解而不能由交换解决，突然变异能够使之摆脱局部收敛而跃出局部解，但是后期的变异可能破坏已产生的对形成最优解有建设性作用的模块。
