抽象概念

Creation of multimedia teaching softwares: guiding by the teaching syllabus of dendrology and the demands of contents, Chinese-English bilingual multimedia teaching softwares are created to make salient features of trees combine with relative images. That helps students easily and intuitively to master plant characters and their English terms at the same time.

制作多媒体教学软件：根据教学大纲和教学内容，利用收集的图片、图像资料制作同时具有中文和英文的双语多媒体课件，教材中的树木文字描述特征与相应的图片紧密结合，使抽象的概念与直观的图片形象，让学生在掌握植物中文的特征同时也掌握相应的专业外语。

Dendrology is a difficult course for its abundantly abstract and trivial contents. The key to a better teaching result for the course is that teachers should not only master relative concepts, terms and feathers of trees, but also pass them to students by appreciate methods while increasing students' interests to the course. A challenge is that there are numerous terms about trees and most of them are difficult and unfamiliar words to most people.

树木学是一门内容较深奥抽象又纷繁琐碎的学科，老师对概念、术语和树木特征的准确把握并把其恰当传授给学生、激发其对课程的学习兴趣是教好树木学的关键；而有关树木和植物分类学的术语对大多数人而言又是很偏僻、难以掌握的词汇，且其数量巨大。

While you can have dialectal variations of words, you can't have abstract concepts appear as an object — like happiness, sadness or nostalgia — in any language.

你能使用方言变化过来的单词，但你不能使概念抽象成物品—像高兴，伤心或怀旧—不论用任何的语言。

The didactics of pathological quality-oriented experiment is feasible and should be spreaded.

素质实验教学是可行的，有助于学生对病理学中抽象的概念、病理变化的理解和掌握，提高了动手和独立分析解决问题的能力，加深对病理最终诊断意义的理解，值得进一步实践推广。

Surface blending in terms of geometric continuous is more practical and welcome with view of geometric interpretation which is different to the traditional differential method based on algebra.

几何连续是对参数曲面中参数连续度量进一步深刻的认识和研究。它是可微性的代数概念的几何抽象，克服了参数连续对曲面苛刻，高阶及结果失真等缺点。

Taking the conceptual model in electrostatics and the conditional model in mechanics as two examples,the author points out that the process of selection and abstraction of the major and minor factors is the premise to the establishment of a model.

理想模型是物理学研究的重要方法之一。从静电学中的概念模型和力学中的条件模型的数量关系，分析了主、次要因素的取舍及其抽象是建立模型的前

The main work and innovation of this dissertation are: 1. The network management domain-specific mobile agent system architecture and mobile agent model are proposed and described in details. The lifecycle of mobile agent is described by using state diagram. The layered security model is introduced. The mobility model is distinguished by the complete and partial one as well as the explicite mobility and implicite one. 2. Aimming at the complexity and heterogeneity of the network, the abstract network entity is presented and defined in details. The mobile agent is also classified and studied from the point of the mobile mechinisim along with the resposibility view. The NMBMA, which the main component is ANE, is put forward and described by using organizational, informationl, computational and implementary model. 3. The two architectures, NMBMA and Client/Server-based one, are compared and analyzed quantitatively and qualitatively. 4. The prototype based on the above NMBMA is designed and some examples are described in the prototype.

主要工作与创新是：提出并详细描述了面向网络管理领域的MAS结构和流动软件代理模型及其内部结构，并采用状态图描述了流动代理的生命周期；提出了层次的安全模型；从数据管理和实现方式两个方面，区分了流动模型即完全流动和部分流动以及显式流动和隐式流动；针对网络的异构性和复杂性，提出了抽象网络实体ANE的概念，并进行了定义；从流动机制和职能两个角度，对流动代理进行了分类研究；以ANE为主要部件，从组织模型、信息模型、通讯模型、实施模型四个侧面描述了NMBMA；定量和定性比较分析了NMBMA与传统的基于Client/Server模型网络管理体系结构；通过一个原型系统的设计和网络管理实例，验证了NMBMA是可行的。

On the basis of the explicitness that the introduction of"the future"into education has its inner and outer foundations, the author makes a further research on such questions as"future image","the future consciousness"and"curriculum design and implementation"which are closely related to the introduction of"the future"into the field of education.

论文针对"未来"含义不断发生变化的特点，没有把"未来"具体化，而是把"未来"作为一个经过抽象概括了的概念来对待，力图通过对于"未来"在教育中引进的有关基本理论问题的初步研究，为教育在今后有效地应付不断面临着的"未来的冲击"提供一种基本的思维方式和操作步骤。

By making analyses,it is proved that the granules involved in rough set,quotient space and concept lattice can be described by abstract granules.Thus,the granules obtained by means of different ways achieve the unification,which will provide a way for formulization on granular computing.

通过分析处理，证明了粗糙集、商空间和概念格中出现的粒都可以采用粒空间中的抽象粒予以描述，使得以不同方式获取的粒得到了统一，从而为粒计算的形式化定义提供了思路。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
