刍议速写

通过阐述速写的涵义、速写与素描的区别、学画速写的目的及方法,指出速写中的艺术表现是以忠实作画者视觉和情感的真实为宗旨的,只有作画者对物体有深刻的理解和准确的体验以及具备精湛、高深的绘画技巧,才能画出好的速写.     

建筑速写表现形式漫谈

建筑速写不但是训练建筑设计师徒手表现能力的手段,更重要的是在建筑速写的训练过程中,提高设计师对美的表现能力和审美趣味。一个表现力极佳的设计草图,不但体现了设计师的设计思想,同时体现了设计师的设计表现能力,造型能力,审美能力。画好建筑速写也是体现一个建筑设计师全面修养的重要方面。     

高职院校建筑装饰专业《美术基础表现》建筑速写教学探讨

建筑速写是高职院校建筑装饰专业《美术基础表现》课程中的主要内容,其目的在于提高学生对建筑空间造型的感受力和把握力。文章首先分析了高职建筑装饰专业教学中建筑速写的课程设置、教学任务以及教学中存在的问题,然后提出建筑速写的教学优化策略,以期促进高职建筑装饰专业《美术基础表现》教学的开展。     

工科类工业设计专业"设计速写"课程教学研究

设计速写以其简洁、快速的表达方式,在众多的设计表现技法中占有重要的地位。在设计的每一个环节,设计速写都有相应的表现。针对美术基础薄弱的工科学生来说,选择适合他们的学习方法,使其在实践中正确地、全面地认识设计速写在工业设计中的作用及其必要性,则能更好地达到训练的目的,为今后的设计打下良好的基础。     

浅论人物速写创作

人物速写是一种快速的记录方法。属于素描的一种,对于绘画者来说,人物速写不单是绘画者在创作作品时积累素材的重要手段,同时也是一门独立的艺术形式。所以借此机会想共同的探讨一下怎样把这门独立的艺术形式能够更好的表现出来。怎样才能算是一张好的人物速写画呢?我感觉一幅好的人物速写应当具备三个方面的特点"形""神""意"。首先是"形"。"形"在人物速写的层次上理解可以分为两个方面,     

构图问题初探

构图是画面的基本形式,画面的基本形式结构是绘画语言的核心。构图的过程就是赋予画面秩序的过程,是对美的发现和表现的过程。研究构图必须研究视觉要素和构图原理。     

关于表现主题与开放式构图的研究

摄影创作离不开构图,构图是表现作品内容的重要因素,是作品中全部摄影视觉艺术语言的组织方式,它使内容所构成的一定内部结构得到恰当的表现.只有内部结构和外部结构得到和谐统一,才能产生完美的构图.开放式构图具有独特的造型功能和很强的表现力,研究开放式构图对于创作出具有深刻思想内容与完美形式的艺术作品会有很大的帮助.     

摄影构图的技术形态及原则浅探

构图是一门历史悠久的学科,早在摄影出现的2000年前,希腊和罗马人就已经应用了构图法则,这在其建筑中有明显的体现。摄影构图——是为表现某一特定的内容和视觉美感效果,将镜头前被表现的对象以及摄影的各种造型因素有机地组织、分布在画面中,以形成一定的画面形式。1"构图"构图一词是英语COMPOSITION的译音,为造型艺术的术语。它     

数码影像创作的画面构图技巧

构图一词具有多种含义，在拉丁语中，构图具有结构、联结、组成等意义。构图一般分为静态构图和动态构图两种。构图是美术创作中实际动手的开始阶段，也是完成一幅合格画面的基本要求。在《辞海》中，”构图”为艺术家为了表现作品的主题思想和美感效果，把个别或局部的形象组成艺术的整体。因此在我们进行数码影像的创作构图时．如何把人物、环境、物体安排在画面当中以获得最佳布局的方法，在形式美方面诉诸于视觉的点、线、形态、用光、明暗、色彩的配合，符合并满足画面表现和人们审美的各种需要。     

陈有才诗歌的幽默特色

幽默是文学艺术创作中一种轻松而诙谐的表现笔调，通过讽喻、双关等修辞手法揭露丑恶、批判现实。乡土诗人陈有才诗歌中到处弥漫的幽默特质使他的诗歌具有独特的美学价值。归纳之，其诗歌的幽默特色主要表现在——语言幽默：情感上的幽默；故事幽默：细节上的幽默；意境幽默：构图上的幽默；笔法幽默：冷幽默、热幽默等诸多方面。     

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

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.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.
