基于神经网络的识别程序，程序采用三层BP网络训练，采用了普通定义中加入动量因子的训练法，精确度很高。

At the same time ,combining with the scores of nervous functional deficiency and Barthel index,assess the influnce of citrlopram on the rehabilitation of neural function.

将筛选出的76例卒中后抑郁病人随机分为两组：西酞普兰治疗组38例，谷维素对照组 38例，分别给予西酞普兰和谷维素治疗8周。

The definiens and working principle of controllable pitch propeller are introduced, the characters of CPP mechanism are summarized, and three types of shipping are concluded, which is applicable to equip with controllable pitch propeller by compared with pitch propeller. The control system of CPP usually adopts PID control, but the parameter of PID controller is adjusted inconveniently so as not to receive favorable result, therefore, the CPP control system based on fuzzy and neural network control is proposed so that improving the control effect. The result shows that the system design is feasible and effective.

介绍了可调螺距螺旋桨的定义及工作原理，并归纳了可调螺距螺旋桨推进装置的工作特性及特点，通过与定距桨进行的对比分析，总结出适用于可调螺距螺旋桨的三类船舶；目前调距桨控制系统一般采用传统的PID 控制方法，但由于PID控制器的参数不便于调节，不能取得良好的控制效果，从而提出了基于模糊神经网络控制的调距桨控制系统的设计，以提高调距桨在各种工况下的控制效果，仿真试验结果表明了调距桨控制系统设计的合理性。

In this paper, BP neural network was applied to simulating the dehydration reaction of lactic acid.

本文采用BP神经网络对乳酸脱水制丙烯酸的催化过程进行了仿真研究。

And carry out a neural network deign and simulation with MATLAB.

并用MATLAB仿真的方法进行神经网络的设计和模拟。

In this thesis, the stability and Hopf bifurcation of a neural network model described by a delay differential equation are investigated.

中文摘要：本文研究了一类具时滞效应的神经网络模型的平衡点的稳定性以及平衡点失稳后产生的Hopf分岔。

In the second chapter, we study an infinite delay differential equation, the system was widely applied in the biology, neural network and some other fields.

第二章是研究一类无穷时滞微分系统，此系统在生物，神经网络等领域中都有广泛应用。

And experts paid more attentions to integer perception while listening to music.3. It also showed the position effect, that was irregular chords appeared at the third or fifth position, and the swings and the delitescence were quite different. It uncovered the different neural modes at different music perception phases.4. The two components had no significant differences with their swings at the three attention levels. It meant that these two ERP components could be acquired under non-attention condition, and music processing was automatic.

更多伏期更早，表明在时间维度和程度上，专家的整合程度要优于一般被试，专家更加注重对音乐的整体知觉。3通过违例和弦出现位置的不同，如违例和弦分别出现在第三位置和第五位置上的对比研究，发现第五位置上产生的ERAN和N5比第三位置上产生的振幅更大，表明这两种成分受违例位置的影响，揭示了音乐知觉不同阶段认知神经模型的差异。4这两种成分在三种注意水平下没有显著性差异，表明这两种ERP成分在非注意条件下就能够产生，人类的音乐加工是自动的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
