表征

Based on the discussion about perceptional representation, natural language representation and scientific knowledge representation, it is showed that the constructive form has significant influence on the systematic function of representation and the basic aspects it possesses as a representative system.

通过对知觉表征：自然语言表征和科学知识表征三个系统的讨论，可以看到构造方式对表征系统功能的重要影响，以及作为一个表征系统所必备的一些基本方面。

Based on these results, we bring forward some suggestions about mathematics teaching and mathematics learning. The teacher should treat the representation as an important activity when they teach the students how to solve the problems, encourage the students to use intuitionist graphic representation and teach the students to transfer among the different representations.

最后，基于上述研究结论，在数学教学和数学学习上提出以下建议：应将数学表征作为解题的一种重要活动，应该鼓励学生在解决问题乃至数学学习中运用图形表征，在数学教学中应该注重不同数学表征之间的相互转化，这是形成数学深度理解的一种有效途径。

2The research reveals that successful problem-solving is not only rely on the precise concept internal representation, but also rely on the integrated bundle structure of concept internal representation. The construction process of the integrated bundle cognitive structure, includes the re-establishment and re-formation, retrieval clues, re-adjustment and re-composition of integrating multiple forms of concept internal representation.

概念内部表征的应用过程同时也是内部表征的重构过程，其中包括重构概念多重内部表征形式的捆绑认知结构、概念内部表征的串联和检索线索以及概念内部表征的再调整与再修改等认知过程。

The analysis showed that there was more use of verisimilar representations of time in Chinese than in English and this was due to the fact that Chinese language is more iconicity oriented while English is more bounded by gram...

操汉语的人是基于客观真实时间顺序和主观想象时间顺序来构建其句子和概念的，其时间表征多为似真表征方式，英语里虽也有某种程度的似真表征，但说英语的人更多的是依据形态语法和抽象原则来表征时间关系的；时间的隐喻表征在两种语言中既有相同之处也有很大差别，这主要源于不同文化的价值观和认知方式

In this paper,we compared the photodegradation efficiency of nano-titania films by using dichloroacetic acid,rhodamine B and methyl orange as the photocatalytic referents and the ultraviolet lamp as the source light to generate the photocatalytic reaction.

针对纳米氧化钛光催化性能研究中缺乏统一有效表征标准的现状，比较了二氯乙酸、罗丹明B和甲基橙三种光催化活性评价物的热稳定性和对紫外光的稳定性，并以氧化钛纳米薄膜为光催化剂，研究了三种评价物的光催化降解效率表征，以及酸碱度、通氧条件等因素对评价物在光催化活性表征中的影响及其机理，归纳了三种评价物对于纳米氧化钛光催化活性表征的优缺点。

EyelinkⅡis used in experiment 3 to study the external and internal refence fame inmental rotation. The result is that presenting a number with an external referenceframe, subjects\' internal reference frames can be revised. At the same time, thesubjects tend to use frame rotation.

研究四的两个实验分别采用了汉字数字与阿拉伯数字以及经典的心理旋转的三维立体图形探讨了心理旋转中的表象表征与命题表征的转化，发现表象表征的容量组块是4，在4以下时，表象表征占主导地位，心理旋转采用表象的匹配，但在容量组块超过4时，命题表征的优势显现了出来，对于刺激物的整体加工的效果更为明显。

结果表明：(1)采用单个汉字或双字词为材料的实验发现了语音、字形关联效应，这说明模糊痕迹理论中的语义表征可有效的推广到对字形、语音的概括表征；(2)对事件的细节性表征和概括性表征是相对的，在不同的任务下可以发生转化，转化遵循&认知经济&的原则；(3)只有一定程度的概括性才能引发关联效应，概括性存在水平高低之分，高水平的概括能导致更多的记忆错觉，概括水平过低不能引发记忆错觉；(4)关联效应的产生既与学习阶段相关，又与测验阶段相联系，其产生机制非常复杂。

But in the condition when the first project is characters and the end project is pictures , the reaction time is faster when the end project is also characters , along with that the transformation speed of imagery presentation is faster than that of proposition presentation, the reason may be that imagery presentation can stimulate proposition presentation automatically, the transformation is self-moving processing and independent from will, but it is not self-motive but controlled processing and will needs when the proposition presentation transforms into imagery presentation.

但在首项目是字的时候，尾项目是图的条件下被试反应时快于尾项目是字的条件下，又表明图像表征比命题表征的转换速度快，原因可能是由于图像表征能够自动激活命题表征，其转化是自动加工的、几乎不信赖于意志努力的，而命题表征转化为图像表征却不是自动的，而是控制加工的、需要意志努力的过程。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
