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。

The wind convergence, mesoscale cyclone and vertical wind shear at lower levels may produce heavy rainfall. The mesoscale cyclone and vertical wind shear at middle and upper levels may produce strong downburst or hails.

低层水平风的辐合、中气旋、垂直风向切变等可以产生强降水，中高层的中气旋、垂直风切变可以产生下击暴流、冰雹等强对流天气。

The building is defined through the convergence of natural and artificial, interior and exterior, rather than demonstrating a stark contrast between the dualities.

这幢楼可以看作是自然与人工，内部与外部的巧妙融合，而不是生硬地展示二者的反差。

The analysis of wind vectors from automatic surface observations shows that the mesoscale convergence line between the northerlies and the easterlies in lower troposphere is very important to the torrential rain , which determines the locations and timings of the torrential rain .

地面自动站以及加密站风场资料分析指出，低空偏北风与偏东风之间的中尺度辐合线对暴雨发生有重要作用，其出现的时间和位置决定了中尺度暴雨天气的发生时间和位置。

Analysis indicates that the adjacent channel power is a quadratic function of predistorter efficients. A new optimization method is given which uses the predicted ACP surface to obtain fast convergence and simulation results show that a 20dB reduction in the third IMD and a 10dB reduction in the quatic IMD are achievable.

得出结论为：分析表明功放输出的邻信道功率是预失真器系数的二次函数；利用了新的自适应算法即使用预测的ACP曲面以提供更快的收敛速度；仿真结果表明，3阶产物可获得20dB以上的改善，5阶产物可获得10dB以上的改善。
