Algorithm application of neural networks.Ⅲ Implementation of neuro-computers. The main contribution of the dissertation can be summarized as follows: 1 Hopf bifurcation of three kind of neural networks are discussed in detail, including type of discrete time delay, type of time delay with weak kernel and strong kernel as well as the proof of existence of bifurcation. Other problems such as asymptotic stability of bifurcation periodic solution, algorithm of determining the bifurcation direction, asymptotic stability and style of periodic solution are also studied. The average time delay is chosen as the bifurcation parameter, phenomena pertinent to system states of the continuous time delay network with strong kernel evolving from stable to oscillating, then back to stable again are observed.

论文的主要创新之处可以归纳如下： 1）针对目前国内外对神经网络的分岔研究较少的情况，论文中详细讨论了带离散时延神经网络、带弱核的连续时延神经网络、带连续分布时延且具有强核的神经网络的Hopf分岔现象，从理论上证明了Hopf分岔的存在性，并研究了分岔周期解的渐近稳定性，得到了确定周期解的渐近稳定性、分岔方向、周期解的渐近形式的算法；用平均时延作为分岔参数，发现带强核的连续时延神经网络中存在着系统的状态由稳定变化到振荡现象，当继续增加平均时延参数时，又从振荡变为稳定这一特殊的动力学现象。

Being a serious phenomenon of repaying to this, the middle vocational schools hardly lose the education on the students the quality of conducting oneself, and they may face the problem of being difficult to find employment and weak to complete with other graduates, which has cramped the continuous development of the middle vocational education and set a hidden peril for the middle vocational students' healthy "bringing-up".

但是从总体上看，当前我国很多学校做人教育的状况和水平远不能适应时代发展的需要，特别是中等职业学校尤为明显，主要表现在当下许多中等职业学校过多的注重了对职中生进行"何以为生"的专业技能的传授，而相对忽视了"为何而生"的如何做人的教育，由此所导致的职中生做人素质严重缺失、就业困难、竞争能力较弱等问题不仅影响到我国中等职业教育的可持续发展，而且还为职中生以后的和谐、全面发展埋下了"隐患"。

Laurence Cummings, the musical director of the London Handel Festival, suggests multiple causes: more research into period performance that has led to more historically informed playing with smaller musical forces and a clearer, purer sound; the rise of the countertenor, the modern equivalent of the castrato without the unacceptable job requirements; even the growth of the recording industry, always on the lookout for new gems.

劳伦斯·卡名斯，伦敦韩德尔音乐节的音乐总监，道出了其中多方面的原因：对不同时期表演的深入研究导致了更多虽然音乐表现力较弱，但有着更纯粹声音的兼具历史特征的作品的出现；上男高音的崛起代替了原来的阉唱男高音，而且上男高音还不必接受阉唱男高音所必须的令人难以忍受的职业要求；甚至不断成长的音像工业也在一直寻求着新的音乐珍宝。

The qualitative description shows that children have accumulated some concerned knowledge about individual metacognition, but they are ignorant of how themselves get the knowledge; children possess some rnetacognitive strategies, but there are often production deficience and utilization deficiency ; children are less-conscious of the difficulties and the consciousness to ask questions is weak during the course of activities, but with the growing of their age, their emotional experiences in the activities increasingly appear to be dialectically-oriented.

质的描述表明，幼儿积累了一些关于个体元认知的有关知识，但对自己是如何掌握这种知识的不甚了了；他们具备了一些元认知策略，但常会产生缺失和利用缺失；他们在认知活动中对困难的意识性和主动提问的意识性相对较弱，随着幼儿年龄的增长，幼儿对自己在认识活动中的情绪体验越来越表现出一种辩证取向。

In the paper, the theory and methodology of amplitude correction method using average of several points in discrete spectrum, which is suitable for analyzing the dynamic signals of rotating machinery with small varying speed, is proposed and systematically studied.

系统而完整地提出了处理变速机械弱时变响应信号的离散频谱多点平均幅值修正法的理论和方法，严格证明了该方法能精确地计算出平稳信号和频率微弱波动信号的幅值，能近似地计算出幅值和频率均微弱波动的信号的平均幅值，并应用这套理论成功地解释了频率微弱波动信号的幅值谱表现出较严重的"功率泄露"效应的原

Applied in cigarette control system of automation logistics system, industrial equipment field bus control technology has become the most effective tool to solve the question that traditional cigarette production exist raw material prepare time to be long and weak adaptability to market. And its open structure system has created the condition to extend for the system expansion. That applying PROFIBUS bus technology in the control system of cigarette automation logistics system, and solving the existed latent problem, is one of research results for the paper.

And the other is that since when the interaction gets weaker it's easier to do accurate calculations and so that enables us to do calculations to predict the behavior of quarks and muons at very high energy which is useful for describing things that happen at accelerators.

和其他的是，自相互作用时会较弱更容易做准确的计算等等，使我们能够做的计算来预测行为的夸克和介子以非常高的能量是有益的描述事情发生在加速器。

Pure methyl esters were prepared using common oil plant seeds and the fatty acid composition of the achieved oil was measured by capillary column chromatography.The kinds and dosage of reagents for fast preparation of the methyl esters were investigated and the chromatographic conditions using two kinds of capillary columns were optimized.

本研究通过参考文献，直接使用常见油料植物种子制备纯油甲酯进行分析，探讨了快速制备甲酯的试剂选择及用量，强极性和弱极性的两种不同类型毛细管柱的最佳色谱分析条件，并将测定的主要脂肪酸含量与国家标准进行比较，结果较为一致，而且平行测定的相对标准偏差表明方法有较好的精密度和重复性。

It was found that the fluorescence spectra of the products of MMPB with GSH and with Cys both redshifted from λ〓/λ〓=299/355nm to λ〓/λ〓=305/425nm with the different rate. Under the following conditions: pH=7. 0 〓 buffer, T=35℃ and t=25min, the maximal fluorescence wavelengths were at λ〓/λ〓=299/355nm for MMPB-GSH and λ〓/λ〓=305/425nm for MMPB-Cys, respectively.

在pH=7.0的〓缓冲溶液中和35℃下，MMPB与GSH或Cys反应25min后，生成的MMPB-GSH的荧光峰为λ〓／λ〓=299／355nm，且此波长下的最大荧光强度可以稳定3h；而同样条件下，MMPB-Cys的荧光峰为λ〓／λ〓=305／425nm，且荧光较弱。

According to the characteristics of large span structure design, such as big diffrence of collumn force, large span and spacious roof, week linkness of different parts and large displacement of bearing, spacil structure methods such as different types of concrete pile with different length, suitable joint and bearing are adopted to achieve the economical and safe demand
