It employs the complex-valued step function to build neural model, then constructs network structure and decides the number of neurons; it adopts complex-valued Hebbian rules and inner product way to calculate the net weight matrix; then it analyzes the convergence of the network by taking advantage of the definition of energy function. In the image pre-processing stage, 2-dimensional Fourier Transform and Euler's formula are used, respectively, to transfer a gray-scaled image into phase information needed by the complex-valued neural network when stores the traffic sign. In the image post-processing stage, phase inverse transformation is used to change the phase image to gray-scaled image.

采用复数阶跃函数构建了神经元模型，建立了复数Hopfield神经网络结构，并且确定了网络中神经元的个数；借助复数Hebbian学习规则和复数内积法给出了网络权值的确定方法；借用复数网络能量函数的定义，说明了复数识别网络的收敛性；在前期的图像数据处理部分，分别使用离散二维傅里叶变换和欧拉公式，给出了将灰度图像数据转化为复数网络所需要的相位信息的方法，实现了网络对路牌的记忆存储；在后期的图像还原部分利用相位逆变换的方法，实现了相位图到灰度图转化。

Constantine's foundation of New Rome on this site reflected its strategic and commercial importance from the earliest times, lying as it does astride both the land route from Europe to Asia and the seaway from the Black or Euxine Sea to the Mediterranean, whilst also being possessed of an excellent and spacious harbour in the Golden Horn.

面对越来越离心离德有奶便是娘的后期罗马军团，俗话说山高皇帝远，远远座在帝国的中心是无法控制这些戍边罗马军团。

Although the parliament passes some acts about the activities of the domestic industry and commerce and the abroad trade, Edward has to take the Italians as his business agents of imports and exports, and the English businessmen are faced with a lot of difficulties because the businessmen of Italy and the Hanse enjoy some political and economical privileges in England, which consequently harms the political and economical interests of the English themselves. In the later period of the 15th century some of the movements of exclusionism take place in London, Southampton, Bristol, etc.

虽然爱德华统治时期英国颁布了一些推动国内工商业和海外贸易活动发展的法案，他不得不依赖意大利商人从事进出口贸易业务，在英国享有特权的汉萨同盟商人依然损害着英国人的政治经济利益。15世纪后期，伦敦、布里斯托尔、南安普顿爆发的排外运动，反映了英格兰民族意识的觉醒和民族精神的高涨。

In order to further explore the benefits of reasonable exercise on maintaining bone health and examine the effect of exercise on skeleton of young college students, 20 male students of college were divided into exercise group (participates bodybuilding frequently) and control group, some indexes of bone metabolism and bone mineral density were observed and analyzed.

为了进一步论证科学合理的运动有利于维持骨骼的健康和对骨质疏松症的预防作用，揭示体育运动对处于青春后期大学生骨骼的影响，本课题在对部分有关骨代谢的研究成果进行理论研究的基础上，以我校20名男性大学生为实验对象，分为运动组和对照组，观察并分析体育运动对大学生骨密度和骨代谢的影响。

Changing form the existentialism to the ontology is an inevitable outcome of the development in his thought.

从早期的生存论转向后期的存在论，这可以说是思想发展的必然。

This artistic guidance only has auxiliary value in his early thoughts,but becomes indispensable in the later existentialist construction.

这种艺术性的指向在早期思想中只有辅助性的价值，而在后期存在论建构中则是不可或缺的。

The results indicate that, during the early storage period under short time treatment with heat air, the activities of amylase and polygalactouronase are effectively decreased; starch content reduction is inhibited; the degradation speed of pectin and the decrease speed of flesh hardness are slowed down, and the release rate of ethylene in fruit is decreased. During the later storage period, the decomposition rate of middle lamella and primary wall of the Li jujube fruit treated with heat air for a short time is delayed, exosmosis of cell contents is inhibited, and the cell structure is protected, so the storage time of Li jujube fruit is prolonged.

结果表明，梨枣采后贮前短时间热处理能有效地降低早期淀粉酶和多聚半乳糖醛酸酶活性，抑制淀粉水解，延缓果胶降解，降低乙烯释放量，延缓果肉硬度下降速度，后期能延缓果肉细胞中胶层和初生壁分解，阻止细胞内含物外渗，保护细胞的结构，从而延长了贮藏保鲜期。

"Explantation of a prosthesis is not feasible in situations such as a severely ill patient who is not a good candidate for anesthesia and surgery," senior author Dr. Raymund Razonable told Reuters,"or a patient who has poor/weak bone reserve so that reimplantation of a functional prosthesis at a later time is not feasible."

资深的Raymund Razonable博士告诉路透社，"人工关节的植入对于严重疾病不能耐受麻醉和手术患者不能施行，或者骨质储备较差患者行植入术由于后期功能性假肢导致关节再植入。"

The major causes of trauma death was brain injury and exsanguination,the brain injury and torso injury contributed a lot to a high death rate.

颅脑损伤和失血是伤后主要死因，后期多死于并发症或器官衰竭；颅脑和躯干创伤严重影响伤员存活率。

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.
