Firstly, reconstruct attractors in phase spaces using chaotic theory,Secondly fit the attractor s evolvement using BP neural networks, because selecting neural network s input training data using Euclid distance and correlation, improve neural network s associative memory and ratiocinative ability, can better fit the attractor s evolvement.

提出一种将混沌理论、关联度和神经网络相结合的短期负荷预测模型，首先利用混沌理论重构负荷时间序列的相空间吸引子，然后用BP神经网络来拟合空间吸引子的演化，由于使用空间欧氏距离和关联度联合来选取神经网络的训练样本，这样就提高了神经网络对负荷序列混沌特性的联想和泛化推理能力，能够更好的拟合吸引子的演化。

Objective To establish an artificial somatic-autonomic reflex arc in rats and observe the following distributive changes of neural fibers in the bladder.

目的 观察体神经-内脏神经人工反射弧建立后，大鼠膀胱肌间神经丛分布的改变以及神经肌肉接头处的变化。

BACKGROUND: Nerve root retractor is necessary apparatus in nucleus pulposus removal of lumbar intervertebral disc protrusion and lumbar spinal fusion.

摘要背景：神经根拉钩是腰椎间盘突出症髓核摘除和腰椎融合术中必需的器械，传统的神经根拉钩无法量化神经根的拉力，容易引起神经根的过度牵拉。

It is interesting that cervical root avulsion is a relatively frequent cause of superficial siderosis of the CNS. It is possible that trauma to the nerve root damages the fine venous plexus within the root, or the medullary and radicular veins that run along the nerve root, resulting in a fragile vascular scar.

很有意思的是颈神经根撕脱也是相对比较常见的病因之一，可能因为神经根的创伤可损伤神经根处的静脉丛及沿着神经根走行的根静脉，导致脆性血管损伤形成疤痕，当屈伸颈部时因牵引而破裂出血。

图2。 中枢神经系统表面含铁血黄素沉积症中颅神经的易感性与神经胶质长度有关，下图显示了每条颅神经中心部分神经胶质长度与外周组成部分的相对比例。

Aiming at the disadvantage of conventional BP neural network, such as selecting parameter values by the empirical method, slow convergence speed and easy trap into local minimum points, this paper designs an improved BP neural network system. In order to improve the network convergence rate and reduce the training error, this paper optimizes the initial connecting weight value of neural network by the use of ant colony algorithm and trains artificial neural network by Levenberg-Marquardt algorithm.

针对常规BP神经网络参数的经验式取值方法以及收敛速度慢，容易陷入局部最小点等缺陷，设计了一种改进的神经网络系统，利用蚁群算法优化神经网络连接权初值，并采用LM算法对人工神经网络进行训练，提高了网络的收敛速度，降低了训练误差。

The cerebrosides and the gangliosides can also be classed as glycolipids because of the presence of carbohydrate, and the sphingomyelins and the glycolipids can be classed as sphingolipids because of the presence of sphingosine.

脑苷脂类和神经节苷脂因为存在碳水化合物可被划分为糖脂。而神经鞘磷脂和糖脂可被划分为神经鞘脂类，因为存在神经鞘氨醇。

This article based on the existence of neural stem cells location,source,implantation,repair mechanisms and implantation of neural stem cells in the body′s immune response to research.It is found that neural sten cells in repair of nerve tissue defects and promote functional recovery of the nervous system plays an indispensable role.

本文通过对神经干细胞的存在部位、来源、植入途径、修复机制及植入体内后机体对神经干细胞的免疫反应进行研究概述，发现神经干细胞在修复神经组织缺损、促进神经系统功能恢复方面起到不可或缺的作用。

An intimate knowledge of the courses and positional relations to the 12th rib about subcostal nerve, iliohypogastric nerve and ilioinguinal nerve play very important roles in avoiding injury of the 3 nerves during the operation on kidney or lumbar hernia.

熟悉腰上三角前方肋下神经、髂腹下神经和髂腹股沟神经的走行及与第12肋的位置关系，对于避免手术中损伤这3条神经具有重要的实际意义。

Objective To explore the clinical feature in patients with tiger spot fish poisoning. Methods 63patients with tiger spot fish poisoning were observed.The nerve conduction velocity were determined in63patients and60controls. Results Symptoms usually appeared0.5～24hours after eating poisonous fish.

目的 探讨"老虎斑"鱼中毒的临床特征和神经电生理变化特点方法分析63例因食用"老虎斑"鱼中毒患者的临床特征，并测定63例中毒患者和60例正常人的正中神经及胫神经的神经传导速度。

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。
