I should be glad to follow Jung in contrasting hysteria and obsessional neurosis as 'transference neuroses' with the paraphrenic affections as 'introversion neuroses', if it were not that such a usage would deprive the concept of 'introversion' of its sole legitimate meaning.

我很高兴依照荣格所说的，将癔症和强迫神经症称为&转移性神经症&，对比于将妄想呆痴病症称为&内向性神经症&，如果它不是说这样一种用法将剥夺它的唯一合法含义的内向性概念。

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.

According to these features, a hybrid genetic algorithm is developed to optimize the operation of pulverized system in admixing combustion conditions, where a fuzzy neural network is adopted to evaluate admixed coal's slag property, and a radial basic function neural network is used to predict pulverized coal's fineness and mill's outlet temperature.

本文将人工神经网络和遗传算法相结合形成混合优化算法，对电站多煤种掺烧制粉系统运行进行寻优。针对掺烧煤结焦的模糊性和非线性特征，采用模糊神经网络评估混煤的结焦特性，并利用径向基神经网络关联掺烧煤的煤粉细度和磨出口温度。

In fact, case based-reasoning and BP neural network could be combined together to achieve the data fusion on the characteristic level. There is ability of analogizing and concluding in CBR. By using CBR, we are able to accumulate a set of cases.

为了使神经网络和CBR充分发挥各自的优点，互相补充对方的不足，将基于范例推理与并行BP神经网络结合起来共同完成特征级融合处理，提出了基于范例推理与神经网络的结合学习机制。

In this method, wavelet is used to extract fault characteristics and neural network is used to diagnose the faults; the inputs and outputs of the neural network are all memberships concretely, the inputs are the memberships of the crest factor, pulse factor, margin factor, bias factor, kurtosis factor and maximum spectrum on each characteristic domain, and the outputs are memberships of each fault.

即利用小波变换获取特征域，取特征域上的峰值因子、脉冲因子、裕度因子、偏态因子、峭度因子及频谱最大值作为神经网络的输入，并对神经网络的输入、输出进行模糊化处理，以神经网络进行诊断。

According to the afferent code, taste quality, rather than being coded by a single fiber or set of specific fibers depends on the pattern developed across a population of fibers, a cross-fiber patterning.

依照这种输入编码，味觉形式不是由单一神经或一套精确的神经所编码的，而是依赖于一种多神经交叉而发展的，这就是交叉神经系统。

The overall aim of the neural stem cell lab is to understand, at a molecular and cellular level, how endogenous mammalian neural stem cells are generated during development, and how their actions are regulated in the adult CNS, both under normal conditions and following disease or degeneration.

该神经干细胞实验室的总体目标是针对正常条件下和疾病或退化情况下，在分子和细胞水平阐述内源性哺乳动物神经干细胞在发育过程中的产生，以及这些神经干细胞在成人中枢神经系统中活动的调控。

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。
