美术写生中色彩的观察与表现

色彩写生是再现自然、再现生活的强有力手段。在作画过程中 ,正确观察和掌握客观物体的色彩规律 ,能提高对色彩的分辨能力和使用色彩造型的能力 ,是色彩写生的关键。提高作画者的色彩写生水平 ,不仅要强化色彩意识 ,还要掌握色彩写生的整体观察方法和表现方法。一、强化色彩意识色彩是光的刺激而产生的一种视觉效应 ,光是其发生的原因 ,色是其感觉的结果。绘画中的色彩 ,分为写生色彩和装饰色彩两大类。装饰色彩着重研究物象固有色的对比与谐调 ,研究颜色组合和色调的问题。在色彩运用上 ,较之写生色彩注重色的单纯和大色域的对比 ,它的主观…     

浅谈基本色彩理论知识

在绘画中,色彩是一种语言,也是一种重要的表现手段,在理论上认识色彩规律,通过对光源色、固有色、环境色及色相色彩等基本色彩理论知识的学习,从而提高观察色彩和表达色彩的能力,在绘画中表现色彩的真实性。     

紫甘蓝色素变色实验的设计

综合表述了紫甘蓝色素的变色原理图。以紫甘蓝汁作为酸碱指示剂设计实验,在球型冷凝管中制成色彩炫丽的pH色柱,促进学生形成指示剂变色范围的概念,在稀释溶液和测定常见酸碱指示剂变色范围的实验中培养实验者的动手能力,在设计判断盐酸滴定碳酸钠终点现象的实验中激发参与者的创新意识。     

专色油墨配色系统中目标色的测量

专色油墨在包装印刷市场上受到越来越多企业的欢迎。专色油墨配色系统中基础色和目标色的颜色测量决定了配色结果的精度,在分析了配色方法和实验过程之后,总结出影响目标色测量准确度的因素,达到改善配色精度的目的。     

浅议色彩画的学习和训练方法

色彩画的学习是一个实践性很强的学习过程,其目的在于提高学生对形与色的感觉能力和表现能力,以便在今后的习作和创作中更好的使用色彩语言去描绘形象,使其具有更强的创造力和感染力。提高色彩的感觉能力和造型能力的关键是准确。这些能力只能在反复观察、比较和不断修改的过程中才能得以训练。如果在没有掌握基本造型方法之前就想追求风格,摆脱对象而自由发挥,或者是过早的简化造型的某些基本因素,忽视基本功的要求,那样既不利于打好色彩画的基础,也不利于今后个人创作能力的提高。     

纸盒印刷色彩一致性的工艺控制研究

本通过对纸盒印刷生产过程中的重要工艺因素，如工艺方法、承印材料、印刷用色等进行分析，指出其在保证纸盒印刷色彩一致中的重要性；同时对印刷版质量、润版液的pH值及表面张力、水墨平衡状态、叠印率等工艺条件对色彩一致性的影响进行了实验与探讨，给出同色密度偏差、同批同色色差、同批同色墨层光泽度偏差等色彩一致性的重要评价参数及其有效控制方法；并提出具有实际指导意义的几点建议。     

论风景写生中以色造境能力的培养

风景写生是高校艺术学科专业学生的必修实践课程.其主要教学任务是培养学生的造境能力.本文针对当前风景色彩写生中存在的"有色无境"问题,从培养学生"以色造境"的观念意识、根据以色造境能力内容模块进有针对性的的训练、激励学生探索富有个性化的色彩语言和表现样式三个方面对风景写生中以色造境能力培养的方法和途径进行了探析.     

色墨并重 随情赋色——论中国画意象色彩发展之趋势

意象色彩是中国传统美术在中国哲学思想背景下建立起来的色彩文化体系,是艺术家用色彩创造出的心物相契、情景交融、虚实统一的色彩运用体系。中国画的色彩经历了一个由色墨并重到水墨为上再到色墨并举的演化过程。面对丰富多彩的现实生活,我们应该明确意象色彩的价值,色墨并重、随情赋色应是当代中国画的色彩之路。     

焰色试验的改进与探究

为发挥学生的主观能动性,对人教版焰色试验进行了改进。学生自行搜集资料,针对实验中的问题进行改进。用丁烷喷枪对金属与硼砂的混合物进行灼烧,冷却后得到颜色各异的硼砂珠,实验现象明显,硼砂珠可以长期保存,反复观察,实验再现性良好。在整个实验改进过程中,学生的独立思考、分工合作、实验探究、搜集资料的能力都得到了提高。

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
