Aimed at the characteristic of multiple types of faults possibly happened in nuclear power plant, large scale of training sample, and requirement of quick and accurate diagnosing, after the analysis of large sample number generated by large fault type exceeds limitation of 64K paragraph in DOS and large number of local minmum in error surface, measurements of same format of data file, Win95/NT operating system platform, resetting weight learning rate, dynamic training set in quick learning algorithm and improvement on quick learning algorithm using homotopy method which can avoid local minmum points in error surface have been adopted to ensure quickly and effective process of the course of neural network's training and testing.

针对核动力装置可能发生的故障种类多，训练样本规模大，故障诊断需要快速准确的特点等，分析了样本多和故障种类多产生的训练样本量超出DOS段大小和网络误差曲面上局部极小值多的情况，采取了使用相同格式数据文件、Win95/NT操作系统平台，对快速学习算法采用重置神经网络权值学习率和动态训练集、并采用能够有效克服网络误差曲面上局部极小点的同伦方法对学习算法进行改进等措施保证神经网络训练测试过程的快速、有效地进行；针对装置发生的故障须快速、准确诊断的需要，分析了故障的产生对装置参数变化的影响及操纵员对故障诊断的基础，在核动力装置发生故障时参数曲线的变化量与正常运行时参数曲线的变化量存在明显差异的基础上，提出采用参数曲线的变化量作为神经网络的输入，并围绕参数变化量的方法采用二次曲线拟合滤波求变化量和阈值技术来保证神经网络得到精确的装置参数变化量，从而得到准确的诊断结果。

In 8 cm grafted group , all survival dogs(n=5) were held upright with the affected hindlimb extended so that the body's weight was supported by the distal metatarsus and toes.

摘 要：［目的］研究神经长度能否影响化学去细胞神经的质量及化学去细胞异体神经修复犬神经缺损的适当长度范畴。

The time from injury to admission was between 2 monthes214 monthes except 1patient who underwent emergency operation 4 hours after injury ,and 1 patient was treated with debridment and epineurial neurorrhaphy ,7 cases with nerve trunk grafting ,6 cases with nerve cable grafting ,4 cases with neurolysis ,1 case with arthrodesis of ankle.

伤后至入院手术时间除1 例为4 h 外，其余均为2～14 个月。1 例行清创、神经外膜对端吻合术，7 例行神经全干移值术，6 例行神经电缆式移植，4 例行神经松解术，1 例行踝关节融合术。

Thickening nerve trunk and increased nerve trunk signal intensity were more obvious in the CIDP, however no significant changes of nerve root and ganglion were observed in both.

CIDP神经周围无片状高信号，神经根及节无明显增大，神经干及股神经均明显增粗，信号增高。

The vertebrate embryonic structure that is located just dorsal and lateral to the neural tube; it is formed from neural plate cells that break away as the neural tube is being formed; the neural crest develops into the PNS.

脊椎动物的胚胎结构，是在神经管的背向和侧向；他是从神经板细胞形成的，如同神经管被打破而形成；神经冠发展至周边神经系统。

Neuropharmacology is a basic science and forms general neuroscience together with neuro-anatomy, neurochemistry, neuro-physiology, etc.

神经药理学是一门基础科学，和神经解剖学，神经化学，神经生理学等共同形成了综合性的神经科学。

Case of two sporadic cellular neurofibromas with atypia and one widespread hyalinization neurofibroma of the lumbar spine in a 51-year-old man without evidence of neurofibromatosis-1 is reported.

bstract 在这里举一个偶尔发生的异生细胞纤维神经瘤，病患是51岁男性，没有纤维神经瘤病的病史，异生细胞纤维神经瘤发生在腰椎的两个不同地方和另一处的透明化纤维神经瘤。

The neurohypophysis shown here resembles neural tissue, with glial cells, nerve fibers, nerve endings, and intra-axonal neurosecretory granules.

神经垂体类似神经组织，有神经胶质细胞、神经纤维、神经末梢及轴突内的神经内分泌颗粒。

It is a Intracellular Signaling Mechanism as neurocirculatory activator, but also powerfully to activate Hypophysis including adenohypothysis and NeuroHypophysis,Neuroendocrine Cell as NeuroHormonal Regulator for rejuvenescence,and furthermore enable to prevent from Central Pain Syndrome,Psychiatric Disorder and Melancholia.http://neurosignals.

这是一个细胞内信号传递机制作为神经循环系统的启动，而且也有力地启动脑垂体包括腺垂体和神经垂体，神经内分泌细胞作为神经体液调节，返老还童，恢复活力rejuvenescence，而且还能够防止中枢性疼痛症候群、精神障碍和抑郁症

In recent years, rTMS has also been used as a therapeutic tool in a variety of neuropsychiatry disorders such as Parkinson disease and depression that were conceptualized in term of a dysfuction of neuronal circuits and neurons at a cellular and molecular level.

近年来rTMS更是在治疗一系列的神经精神疾患如帕金森病、抑郁等上取得了较好的效果，但其治疗机制尚不明了，而且这些神经精神疾病又被认为是神经环路和神经元在细胞及分子水平上的功能失调，因此探讨rTMS所致的磁刺激对中枢神经系统中神经元基因活性、神经介质或/和调质、结构变化等的调控作用有着重要的意义。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
