The new algorithm is shown to be efficient to overcome the problem of neuron underutilization.

关键词神经网络，竞争学习，矢量量化，神经元欠利用，算法1引言根据Shannon的"率失真理论"，矢量量

Keywords: Neural network, Competitive learning, Vector quantization, Neuron underutilization, Algorithm

与传统竞争学习算法只有一个神经元获胜而得到学习不同，PSCL算法按照各神经元的获胜概率并通过对失真距离的调整使每个神经元均得到不同程度的学习，可以有效地克服神经元欠利用问题。

RESULTS: Four hours after operation, rats injected with bletilla particles developed temporary conscious disturbance, and sustained hemiparesis of contralateral limbs with spontaneous circling behavior. Ischemia or infarction was found obviously in the cortex of parietal, frontal lobes and basal nuclei of the right cerebral hemisphere, where the neurons characterized with vague outlines, pyknosis and necrosis of neuron nuclei were recognized as well. But hemiparesis and spontaneous circling behavior only lasted for 12 h after embolization with bletilla gum.

结果：白芨微粒组大鼠术后4 h内呈现意识障碍，持续性对侧肢体轻度偏瘫及环转，TTC染色显示右侧大脑半球额叶、顶叶皮层和基底核附近局灶性缺血或梗塞，光学显微镜下可见缺血区脑组织水肿或坏死，神经元轮廓模糊，核固缩或裂解等；白芨胶组仅在术后术后1 h内有轻度意识障碍，12 h内出现对侧肢体行动障碍，但未见明显病理改变。

Compared to state-of-the-art methods based on Kohonen's adaptive-subspace self-organizing map, our method avoids confusion of data in the manifold representation. Each neuron in the network approximately learns the mean vector and principal subspace of the data in its local region. The data representation is therefore more discernable.

与现有的基于Kohonen的自适应子空间自组织映射网络(Adaptive-subspace self-organizing map， ASSOM)方法相比较，本文方法有效地克服了流形表达中出现的数据混淆现象，网络中各神经元渐近学习各自区域内样本数据的平均向量和主元子空间，数据表达更加清晰可辨。

OECs were cultured in the olfactory bulb of newborn Wistar rat. OECs suspension was infused into the lateral cerebral ventriculus of EAE rats, and the saline with the same quantity was infused in pseudo-operation group. Afterwards, motor-function grade, histo-pathological change and expression of apoptosis of neuron were observed.

培养、纯化OECs后，移植组将OECs悬液注入EAE大鼠的侧脑室；假手术组按以上方法注入等量生理盐水；观察二组大鼠运动功能评分、组织病理学变化以及神经元细胞凋亡表达情况。

In the same neuron, veratridine (1.5～5.0 μmol/L) caused slow wave oscillations of interspike intervals, while aconitine (10～200 μmol/L) caused tonic firing.

结果发现，在同一神经元，藜芦碱(1.5～5.0 μmol/L)可以引起放电峰峰间期的慢波振荡，即峰峰间期由大逐渐减小，然后又逐渐增大，形成重复的振荡波形，每个振荡持续约数十秒至数分钟；而乌头碱(10～200 μmol/L)则引起强直性放电，即峰峰间期逐渐减小，然后维持在一个稳定的水平。

As a dominant party,CPC government should play a guardian,supervisee and guarantee role to overcome all the difficulties in the development of charitable cause and bring it into full play in the establishment of harmonious society on policies and regulations basis.

在中国共产党的文献中第一次把发展慈善事业提到&最广泛最充分地调动一切积极因素，不断提高构建社会主义和谐社会的能力&的高度来认识。近年来，社会学界对慈善事业的理论专著发表较多，有鉴于此，笔者不揣浅陋，谈谈自己的认识和见解。

Flow through the land, the land of the scale of operation allows the effectiveness of the land may be raised.

通过土地的流转，土地的规模经营可以让土地的效益得到提升。
