The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

By studying and analyzing the various Neural Network and intelligent fault diagnosis, associating the difficulty which is to measure the interior signal of cycloconverter, the thesis puts forward the cycloconverter fault diagnosis which bases on Neural Network and takes cycloconverter input voltage and output current as the input of NN. According to the self-learning and non-linearity of NN, it can confirm the position of SCR fault.

通过对国内外多种神经网络和智能故障诊断技术的分析比较，并考虑到直接检测变频器内部有关信息的难度，本文提出并研究了基于神经网络的变频器故障诊断技术，以变频器输入/输出有关电量特征值作为神经网络的输入，通过神经网络的自学习方式，对变频器内部晶闸管故障进行定位。

Fund Project: the National Natural Science and Technology Source Program, No. 2001DEA1006*Abstract: Number of neural stem cells is small. NSCs look like circle or ellipse with or without short neurite, with large nuclear-cytoplasmic ratio and deep karyotin. NSCs have no visible differences with other kinds of cells in appearance, and have no cell surface marker. Currently, there are mainly three aspects to identify NSCs: expression of specific nerve antigen, including nestin, Musashi, transcription factor, and cell adhesion molecules; self-renewal ability including single cell clone analysis, BrdU mark and S phase cell; the potential of multi-direction differentiation including immunocytochemical process and reverse transcriptase polymerase chain reaction.

由于神经干细胞的数量很少，从细胞形态来看神经干细胞为圆形或椭圆形，无或有较短的突起，核质比大，核染色较深，形态上与其它种类的细胞没有明显的差异，并且未找到一种细胞表面特异性标志物，因此目前鉴定神经干细胞主要有以下3个方面：特异性神经抗原的表达，包括巢蛋白、Musashi、转录因子及细胞黏附分子；自我更新能力，包括单细胞克隆分析、BrdU标记S期细胞；多向分化潜能，包括免疫细胞化学法、聚合酶链反应色法。

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 ultra structural changes of nerve root arc the pathological basis of the function loss of the nerve root. The present model is more closer to the model of lumbar intervertebral disc herniation and stenosis of nerve root compression and it provides a basis for treatment of compression caused radicular pain and numbness in clinic.

神经根超微结构的改变是神经根失功能的病理形态学基础，此模型更接近于腰椎间盘突出和椎间管狭窄对神经根的压迫，为临床神经根性疼痛及麻木治疗的研究建立了可供参考的动物模型。

With introducing the Proportional to Population Size Sampling technique into resample for the problem of specimen reconstruction effectiveness and rationality, a neural network ensemble method based on the PPS technique was proposed, which could improve the accuracy of individual network and the differences among individual networks; and a new dynamic selection approach of individual network in a neural network ensemble was put forward.

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。

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。
