Plenty of samples is provided for training BP neural network by traditional design method and the topology structure is built using forward propagating data and backward propagating error data, which is applied to optimal design of parallel double broken line pulley in order to accomplish the mapping between main parameter of hoisting mechanism of gantry crane and the related parameters of parallel double broken line pulley.

利用传统的设计方法为BP神经网络的学习提供足够样本集，然后通过正向传播和误差反向传播建立BP神经网络的拓扑结构，并将其应用于平行双折线卷筒的智能设计中，以完成龙门起重机起升机构主要设计参数与平行双折线卷筒相关参数的映射，提高设计的质量和效率，为龙门起重机关键零部件的智能设计提供一个新的途径。

Finally a huntsman came by with his double-barreled gun on his back, and a sword at his side.

最后一个猎人朝它们走来，他肩上扛着双筒猎鎗，腰间还插着一把猎刀，狐狸对狼说：「那个就是人，你该朝他扑过去，我可是要回我洞里去了。

Finally a huntsman came by with his double-barreled gun on his back, and a sword at his side.The fox said to the wolf,"Look, there comes a man. He is the one you must attack, but I am going back to my den."

最后一个猎人朝它们走来，他肩上扛着双筒猎枪，腰间还插着一把猎刀，狐狸对狼说：「那个就是人，你该朝他扑过去，我可是要回我洞里去了。

Finally a huntsman came by with his double-barreled gun on his back, and a sword at his side.The fox said to the wolf,"Look, there comes a man. He is the one you must attack, but I am going back to my den."The wolf then charged at the man.

最后一个猎人朝它们走来，他肩上扛着双筒猎鎗，腰间还插着一把猎刀，狐狸对狼说：「那个就是人，你该朝他扑过去，我可是要回我洞里去了。

This paper develops a high-frequency welding power source with double-ended flyback topology.based on SG3525 a new type of control program is designed which with controlled pulse energy output characteristics, pulse width and frequency can be controlled, to control output energy.

本文给出一种基于双端反激式主电路拓扑和SG3525 PWM控制芯片，研制了一台高频脉冲能量可控式焊接电源，该电源通过对输出电流的脉宽和频率单独控制，从而控制输出能量。

Opposition manager Ian Dowie joined in the support for Lampard, saying: Frank's a top player but Scott Carson made a fantastic penalty save. You have to give credit to our goalkeeping staff because we studied videos of Frank's last seven or eight penalties.

昨晚的对手查尔顿的主教练道伊也对此发表自己的看法：兰帕德当然是名顶尖的球员，但是昨晚我们的门将斯科特·卡森精彩的扑出了他的点球，因为赛前我们已经研究了他的7～8个点球。

By level function,ε-subdifferential, normal cone and dual function, global optimal solutions for a convex function in locally convex topological vector space and a few of equivalent forms on it are obtained. Maximum points are characterized.

讨论局部凸拓扑向量空间中凸函数的全局最优解，用水平函数、ε-次微分及法向锥和共轭函数等工具刻画其最大值点，得到最优解的几个等价形式。

The model was preprocessed to assure the regulation of facets, create the dual graph of it, and then adapt Reeb Graph to extract the skeleton which contains enough information of the model, such as gesture and topological features, to be able to be used as descriptor of 3D model retrieval.

通过对模型进行一定的预处理保证面片的规则，定义面片间距离计算方法，创建模型的对偶图，识别连通分量，在连通分量上应用Reeb图的计算思想抽取原模型的骨架。试验表明，该算法具有较好的计算效果和效率，最终的骨架保存了模型的拓扑连通性以及姿态，可用于基于内容的三维模型检索时的特征描述符。
