Second, mordern science investigates Nature only through mathematical way, which make people take the mathematical nature for Nature itself. Third, its result is physicalistic objectivism was seen as the metaphysical foundation of natural science which has led to the riddle of cogni...

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。

In modern researches on the grain-size characteristics of lake sediments, the methods of incertical dividing sediments grain-size have no rigorous mathematical theory to support. To resolve this omission, the case of pollen zonation was taken for reference. 338 samples measured by Mastersizer 2000 from DG02 core of Gahai lake in Qaidam Basin were studied. Considering the clustering results of sequential clusters did not change the sequence of samples, tilia software package was used to divide the dividing sediments grain-size.

针对现阶段湖泊沉积物粒度特征研究中垂直剖面分层方法所存在的数学方法的不足，借鉴孢粉分带比较成熟的案例，应用有序聚类法中次序不变的特点，以柴达木盆地尕海湖DG02钻孔338个经激光粒度仪测试的样品为研究对象，在有序聚类的数学理论基础上，借助Tilia软件将湖泊沉积物垂直剖面进行分层。

In this paper, some methods of fuzzy mathematics suah as the direct method of fuzzy pattern recognition, the method of fuzzy clustering analysis the method of fuzzy information retrieval, and the recently advanced method of fuzzy fractal dimension have been applied to earthquake monitoring and prediction in the Surrounding Capital Area based on the seismicity and earthquake precursors. The seismic and unseismic precursors before both the Tangshan M=7.8 great earthquake in July, 1976 and the Datong-yanggao M...

本文把模糊数学中的模糊模式识别的直接方法、模糊聚类分析方法、模糊信息检索方法和新近提出的模糊分维方法应用到以地震活动性和地震前兆为基础的首都圈地震监测预报当中，分析研究了发生在这一地区的两次大地震，即1976年唐山7.8级和1989年大同6.1级地震前用模糊数学方法识别出的地震学前兆和非地震学前兆，并对这一地区大地震的长期和中短期模糊预报方法与途径进行了简要的讨论。

The model of mine's trajectory is built,and the model of wallop is built.Then the underwater trajectory of the airdropped mine is simulated by Matlab/Simulink.At last,This paper gets the result of simulation and analysis.

在建立了六自由度的水雷水下弹道数学模型和水雷入水击水力计算的数学模型基础上，通过实例对水雷的水下弹道在Matlab/Simulink环境下进行了仿真计算，最后给出相应的仿真结果和分析。

After that, the process and method of life-cycle design are studied according to the process of green product life-cycle and the priority strategies of life-cycle design are concluded as a whole. In chapter 4, argues that Clean Production Technology conciliates social economy development and environment protection on the basis of relationship analysis among society economy, environment and clean production technology from the perspective of modern Eco-economics. It is proposed that resources cost should be equal to marginal opportunity cost from the point of sustainable development.

第四章从现代环境经济学和可持续发展观点出发，深入地分析了社会经济、环境和清洁化生产技术之间的关系，并从可持续发展角度出发阐释了以边际机会成本作为资源成本的原由及构成；在此基础上，采用数学方法分析了企业清洁化生产的过程，推导了企业清洁化生产资源边际机会成本最小化的约束条件，并研究了企业清洁化生产的技术、经济、环境数学模型。

On the basis of analysing the mine production and haulage System the basic concepts and calculating methods for the reliability degree of mine production and haulage system are put forward The mathematical models for assigning the reliability degree and deigning the system are established in this paper .

本文在分析矿井生产运输系统的基础上，提出了矿井生产运输系统可靠度的基本概念及其计算方法，建立了可靠度最优分配的数学模型及最优生产运输系统可靠性设计的数学模型

The creation of calculus is the most glorious chapter in mathematical history, it is the essence of mathematical thought, spirit and methods, and erects a firm foundation for the establishment of numerous other branches of mathematics.

微积分的发展是数学史上最辉煌的一章，它凝聚了数学家的思想、精神和方法，为众多数学分支的建立，奠定了坚实的理论基础。

In the same time, learning disability handicaps the improvement of the whole educational levels.

在此基础上，用基于小生境技术的遗传算法对排样库中的零件进行排样：先建立优化排样的数学模型，根据该数学模型将多边形在矩形板料上的排列方式转化为特定的编码，并建立编码和和排样方式的映射模型，然后采用基于小生境的遗传算法对排样过程进行优化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
