This article puts forward a solution named divide - assemble by deducing the size of bp neural network to overcome entering the local best point , the dividing process is that a big bp neural network is divided into several small bp neural networks , every small bp neural network can study alone , after all small bp neural networks finish their study , we can assemble all these small bp neural networks into the quondam big bp neural networks ; on the basis of divide - assemble solution , this article discusses the preprocessing of input species and how to deduce the size of bp neural network further to make it easy to overcome entering the local best point ; for the study of every small bp neural network , this article adopts a solution named gdr - ga algorithm , which includes two algorithms . gdr ? a algorithm makes the merits of the two algorithms makeup each other to increase searching speed . finally , this article discusses the processing of atm band - width distribution dynamically 本文从bp网的结构出发，以减小bp神经网络的规模为手段来克服陷入局部极小点，提出了bp神经网络的拆分组装方法，即将一个大的bp网有机地拆分为几个小的子bp网，每个子网的权值单独训练，训练好以后，再将每个子网的单元和权值有机地组装成原先的bp网，从理论和实验上证明了该方法在解决局部极小值这一问题时是有效的；在拆分组装方法基础上，本文详细阐述了输入样本的预处理过程，更进一步地减小了bp网络的规模，使子网的学习更加容易了；对于子网的学习，本文采用了最速梯度? ?遗传混合算法(即gdr ? ? ga算法) ，使gdr算法和ga算法的优点互为补充，提高了收敛速度；最后本文阐述了用以上方法进行atm带宽动态分配的过程。

The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation . the result shows that welding residual tensile stress appears in the weld and its area nearby , and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding , and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time , heating temperature , heating area , and inversely proportional to cooling area , and welding residual tensile peak stress in the dangerous area is decreasing trend earlier , and then increasing trend later with heated location increased 本文利用数值模拟手段对转轮的焊接工艺从分段焊和局部加热两个方面进行了优化,结果表明:采用普通工艺焊接时,叶片焊后残余拉应力出现在焊缝及其附近区域,并且在叶片出水边的熔合线附近(危险区域)出现了峰值;在采用优化的分段焊时,先焊两端后焊中间的方法可以降低叶片危险区域的焊接残余拉应力峰值,降低效果与叶片出水边焊段长度、焊缝各段的焊接方向有关;局部加热法降低转轮危险区域残余应力的效果主要与加热时间、加热温度以及加热面积成正比,与冷却面积成反比,并且危险区域的残余应力随加热区域的增大呈先降低后升高的趋势。
