Psychology}, the paper defines intuition as a cognitive ability to make immediate judgement without analyzing or reasoning and further analyzes the relation and difference between intuition, inspiration, insight, imagination and perceptual intuition, pointing out that mathematical intuitive thinking is a swift judgement on and imagination to the objects of mathematics and their relationship in structure which is featured by illogicality, directness, probability, randomness and unity and aids students in predicting conclusion or direction to solution as well as making definite choice between several options, Furthermore, the paper probes into the foundation of mathematical intuitive thinking in terms of psychological mechanism, and thereupon holds it necessary to develop students mathematical intuition in that it does good to the excitement of creativity, improvement of overall qualities, all- brain development and optimization of mathematical thinking among students.

而数学直觉思维就是人脑对数学对象及其结构关系的一种迅速的判断与敏锐的想象，并探讨了数学直觉思维的生理机理基础，总结其特征有非逻辑性、直接性、或然性、随机性、整体性和综合性。在解题时直觉能帮助学生对结论或解题方向做出预见，也可以在推理面临多种可能性时，帮助学生做出果断的选择。

Based on the experiments of physical properties of desert sand,the driving force of running desert wheeled cross-country vehicle were obtained by calculating force between tire and sand.The experiments about pressuring grass resistance of lengthways lay out grass mechanism were done.According to the vehicle terramechanics theory,desert trafficability of straw-checkerboard sand barriers paving robot was analyzed.

Gui Xiaohu's "Do not watch" series may involve triple ambiguous: First, the material from his anti-vice picture, this is painting with images of disputes over the other; secondly, he has chosen and reproduced these images, it constitutes a peep again; Thirdly, the peep makes the theme of sex and violence implicit social criticism, and in highlighting the plight of ethics at the same time, the works themselves were placed in a moral dilemma.

桂小虎《勿视》系列可能涉及三重暧昧：其一，他的素材来自扫黄图片，这是绘画与图象的纠葛；其二，他选择并再现这些图像，本身即构成再度窥视；因此其三，这一窥视，奇异地，使性与暴力的主题隐含社会批判，而在凸现道德困境的同时，作品本身被置于道德的困境。

The paper reviewed the host selection mechanisms and rules of xylophagous insects and their application foreground in forest health evaluation. According to the rule that some secondary xylophagous insects always accompany with trees which are sub-healthy or unhealthy, ideas of diagnosing and evaluating forest health betimes using xylophagous insects were posed. Mathematical models would be established based mainly on interactions between quantity of xylophagous insect populations and status of forest health, interspecific interactions (community structure, biodiversity) and environmental factors were also added as supplementary parameters, in order to quantitatively analyzing and comprehensively evaluating forest health and its developing trend.

本文综述了蛀干昆虫对寄主植物选择机制和规律的国内外研究进展及其在森林健康评价中的应用前景，根据蛀干昆虫中次期性种类总是与亚健康和衰弱林木相伴的规律，提出了利用蛀干昆虫早期诊断和评价森林健康的思路，以蛀干昆虫种群数量与林木健康状况的相互关系为主，辅以物种间相互作用关系、环境因子等建立数学模型，定量分析和综合评价森林健康及其发展趋势。

In this dissertation, the weak gels with good thermal stability and/or salt tolerance for use in EOR were prepared from HPAM and aluminium citrate or the compound containing hydroxymethyl groups in aqueous solution. The gelation mechanisms, structure, and properties of the HPAM-AlCA and HPAM-PRIM gels were investigated. For the HPAM-AlCA gelling system, the effects of aluminium : citrate and pH value on the properties of AlCA were systematically studied.
