Our study contained three sub experiments: First, we looked into the music perception neural mode under the u...更多n-attention condition, then pre-attention condition, and attention condition at last. It suggested that:1. Similar to the past studies, ERAN was also acquired when irregular chords was played to both music experts and ordinary persons, with the former swings larger than the latter ones, and the former delitescence earlier than the latter ones.2. N5 was also acquired in the same condition, and it reflected the conformity process of music perception. The swings of experts' N5 were lager than the ordinary ones, and delitescence earlier.

本研究分为三个实验进行：实验一即在非注意实验条件下进行音乐感知能力的研究；实验二即在前注意实验条件下进行音乐感知能力的研究；实验三即在注意实验条件下进行音乐感知能力的研究，研究结果表明：1类似于前人的研究，不规则和弦在音乐专家和普通人中都产生了右前负极性，音乐专家的ERAN比普通人的振幅更大，潜伏期更早。2伴随着ERAN，不规则和弦在音乐专家和普通人中还产生了晚期负极成分(简称N5)，它反应了音乐的整合。

On the basis of expectation disconformity pattern, considering simultaneously equity pattern and need disconformity pattern, this model introduces perceptive equity and perceptive price variables, and designs the corresponding observable variables and path relations for these structural variables.

该模型在期望不一致模式的基础上，同时考虑了公平模式和需要不一致模式，引入感知公平和感知价格变量，并为这些结构变量设计了相应的观测变量和路径关系，建立了由顾客满意、企业形象、感知价格到顾客忠诚三条路径关系，改变了传统模型中从顾客满意到顾客忠诚路径过于单一的情况。

Finally, as appropriate ways of presenting awareness information will promote cognition ability and it is difficult to know users editing intention in ubiquitous environment, we present the semantic awareness model based on various types of objects such as graphic and image. Related techniques like sematic maintenance, semantic conflict detection and solution are proposed to provide better awarenss.

There were differences in peer relation and classroom structure among male students of sociometric statuses, while there were no such differences among female students of sociometric statuses (3) perceived interpersonal harmony by students was positively correlated with their prosocial behaviors, but were uncorrelated with aggressive behaviors; peer relation was negatively correlated with shyness-sensitivity.

2在男生组中，不同社会测量地位学生在班级人际和谐的同伴关系和班级组织上有显著的差异。而在女生组中，不同社会测量地位学生在班级人际和谐的各个维度上均无显著性差异。(3)学生感知到的班级人际和谐与亲社会行为之间存在显著正相关，学生感知到的人际和谐与攻击行为之间相关不显著，感知到的同伴人际和谐与儿童的羞怯－敏感性有显著负相关。

Through analyzing the questionnaire of tourists, we try to inquire into the tourism motivation of tourists, the difference between tourism expect and tourism apperceiving, applying"authenticity"and"role playing"to fix the"tourism situation"of The Dai Park; Through analyzing the questionnaire of inhabitants, we try to inquire into the whole apperceiving of developing tourism, mainly into the culture apperceiving and investigate whether they join in village tourism; Through spot coverage and investigation we find there are some contradictions and negative effects existing in the tourism development of The Dai Park, The Xishuangbanna Dai Park Company, Ltd, as the manager of The Dai Park should promote developing tourism and coordinate inside contradictions.

通过分析旅游者调查问卷了解旅游者旅游动机，旅游期望与旅游感知的差距，引入旅游社会学中&真实性&与&舞台性&对傣族园的&旅游情形&进行定位；通过分析居民问卷试图了解村寨居民对于发展旅游的总体感知，重点分析其文化感知，调查其对于参与村寨旅游的看法与意愿；通过访谈与实地考察发现，傣族园旅游发展中客观存在交错复杂的矛盾冲突，旅游发展的负面效应也有所显现，作为景区管理者的傣族园有限公司应发挥促进旅游发展与协调内部矛盾的主要职能。

We define some perceptive parameters, such as the change of texture character,histogram,frequency spectrum ,knowledge of image,and we calculate the perceptive information using sigmoid function.
