重构在面向对象设计中的应用

重构是在保持程序可观察行为的前提下对程序内部结构的改进，作为一种重要的面向对象设计辅助工具，重构在面向对象设计过程中有着广泛的应用。其中一种重要的应用是面向对象设计改进。在面向对象设计中存在两种设计改进过程：1、全新系统的设计过程。面向对象系统的设计过程就是一系列的在原有设计基础之上的设计改进过程。2、旧系统的再设计过程。这种过程通常存在于系统维护阶段。在面向对象设计中使用重构可以使设计改进达到一定程度上的自动化。本文主要阐述在面向对象设计中如何使用重构实现设计改进。

掌握三维设计技术提高机械专业毕业生的毕业设计水平

微型计算机的三维设计是设计领域的一场变革。正确地、清楚地认识三维设计系统及其相关的知识,才能使我们更好地去掌握三维设计软件,并且更快地掌握和运用它。传统的二维设计已经无法满足现今工业设计的需要,只有三维设计才是工业设计的出路所在。对于熟练掌握与运用三维软件技术是毕业生进行全面而综合设计的重要工具,仅有通过三维设计,才能更好地体现现代设计理念与掌握现代设计的精髓所在。因此,掌握三维设计技术,是提高机械专业毕业生毕业设计水平,使其得到全面锻炼的必由之路。     

浅析概念设计

概念设计是利用设计概念并以其为主线贯穿全部设计过程的设计方法。概念设计是完整而全面的设计过程，它通过设计概念将设计者繁复的感性和瞬间思维上升到统一的理性思维从而完成整个设计。概念设计围绕设计概念而展开，设计概念则联系着概念设计的方方面面。     

设计批评浅谈

设计批评是现代艺术设计理论不可分割的组成部分。设计批评是对一定的设计实践进行分析研究,进而作出判断和评价的一种科学活动。设计批评对于设计本身是很有现实意义的。设计批评对于设计活动的各个环节都能够给出直接的、独特的、指导性的作用。设计批评赋予我们深刻的洞察力、分析力、判断力,宽阔的视野和灵活性。所以设计批评对于整个设计活动都是非常重要的。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Jane Eyre——A Feminist In The 19th Century

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-
