Based on traditional wood fiber processing way at home and abroad, this paper draws up mathematical description theory of wood fiber, finishes the mathematical description theory of single wood fiber, sum up the reason of low density of wood fiber at microcosmos state, completed the laboratory study on Micron Flake Fiber High Strength Board, set up the forming methodology of this kind of wood-based panel.

本文在总结国内外传统法木纤维加工的基础上提出了木纤维数学描述理论，进行了单个木纤维细胞的数学描述，总结了现在木纤维强度低的微观原因，完成了微米长薄片木纤维高强度人造板的实验室研究，创立了该板种的形成方法学，所提出的MFB形成理论体系和加工方式，是利用木材微纳米技术在人造板加工业中开创出的一片新研究领域，提出了微米纤维细胞劈裂的条件。

Then the author reviews the content of risk analysis of regional natural disasters and the mathematical models of risk assessment. The risk analysis is classified into three steps, risk recognition , risk estimation, and risk assessment and the mathematical models into three types, extreme risk model, probability risk model and possibility risk model. Nextly, the possibility risk model for analyzing regional disaster risk are reviewed thoroughly.

综述了区域灾害风险分析的内容及区域灾害风险估算的数学模型，指出风险分析可归结为风险辨识、风险估算、风险评价三个环节，风险估算数学模型的演进可概括为极值风险模型、概率风险模型、可能性风险模型三个阶段，着重介绍区域自然灾害风险分析的可能性风险模型。

" In 1981, the Supreme Court stated that "a claim drawn to subject matter otherwise statutory does not become nonstatutory simply because it uses a mathematical formula, computer program, or digital computer" and a claim is patentable if is contains "a mathematical formula and implements or applies the formula in a structure or process which, when considered as a whole, is performing a function which the patent laws were designed to protect.

& 1981年，最高法院指出，&索赔提请法定事由，否则不会成为非法定仅仅是因为它使用了一个数学公式，计算机程序，或数字电脑&，并要求具有专利性，如果是包含&一个数学公式，并在实施或适用的公式的结构或过程，当作为一个整体考虑，是履行这一职能的专利法是为了保护。

The result revealed that 1 From the cultural point of view, the tension between Tayal culture's "speech-based representation system" and Chinese culture's "character-based representation system" cause Tayal students difficulties carry out the transformation of representations. 2 Tension formed between Tayal students'"wholeness and conferring of meaning" thinking framework, and "partialness" presented in teaching material and teaching activities, is unfavorable for their understanding of mathematical concepts. 3 Tension is formed between Tayal culture's "open ended discussion" style and "close ended discussion" style in mathematics class, which lowered the opportunity for Tayal students to communicate mathematical knowledge.

研究结果发现：从文化的角度来看，泰雅文化的「言说表徵系统」与汉文化的「文字表徵系统」之间的张力，导致泰雅学生不易进行数学表徵的转换；泰雅学生「整体观及意义赋予」的思考方式与教材或教学方式所呈现的「部分观」所形成的张力，不利於泰雅学生理解数学概念；泰雅文化的「开放式对谈模式」与数学教室的「封闭式对谈模式」所形成的张力，减低了泰雅学生沟通数学知识的机会。

本文认为，胡塞尔的科学批判虽具有重要启发意义，但从科学和科学哲学的角度来看，他的批评在某些方面是不恰当的：①实证主义科学观固然不是健全的科学观，但现代科学自身却不是意义、价值等形而上学的领域；②尽管数学化的自然并不是自然本身，但数学化却是现代科学最有效、最可靠的方法；③胡塞尔反对任何实在论的自然观，但这种自然观是现代科学世界观的基础。
