基于采煤机截割路径的动态三维地质模型构建方法

针对虚拟综采工作面难以构建实时动态煤层的问题，提出了一种根据采煤机行走轨迹构建三维地质模型的方法.建立了初始三维地质模型和动态三维地质模型，并提取了目标煤层的轨迹曲线，为采煤机提供了目标截割路径;基于当前工作面采煤机的实际截割情况及未来发展趋势提出了三种采煤机截割方案，分别是采煤机记忆截割、人工干预的采煤机记忆截割和采煤机自主截割;建立了真实的虚拟综采工作面，构建了三种方案的实际煤层形态，并进行了仿真对比实验.结果表明:通过采煤机自主截割方案构建的实际煤层的总体平均误差为15.73mm，能够实现较小的割岩量和较高的回采效率.

Whewell on the classification of the sciences

Despite deserving a place amongst the historic milestones of the philosophy of disciplines, the system of the sciences put forward by Whewell has so far received little interest. Yet his ideas had a significant impact on the researches subsequently carried out on the topic, exerting in particular a decisive influence on Peirce and Spencer. The present paper aims to display the innovatory nature of the philosophical foundations of the Whewellian classification of the sciences. In this respect, we will argue that the most striking feature of his disciplinary system lies in a heuristic categorization of the sciences according to their “methods of discovery”. This represents a double departure from both the Aristotelian and the Baconian disciplinary paradigms, which are instead underpinned by ontological and epistemological criteria, respectively. Next, we will explore the pivotal role of Whewell's classification of the sciences for his overall project of a philosophy of scientific discovery.     

Three principles of unity in Newton

I discuss three principles of unity available in Newton’s physics, appealing to space and time, causal interaction, and law-constitution respectively. I compare these three approaches with respect to aggregation (how a collection of entities can compose a whole) and multiplicity (how the world as a whole can contain a multiplicity of genuine unities), outlining the problems faced by the first two approaches and arguing that the third looks a promising candidate for further philosophical investigation.     

试论1879～1880年英波同盟及其影响

以《英国外交事务机密件》为依据，详尽论述英波同盟的背景、经过、影响等，使我们对中亚史上这一鲜为人知的历史事件有一全新的体认。英波同盟在中亚产生深远影响，它加速了中亚独立国家沦亡半殖民地、半封建化的进程。     

Quine's ‘needlessly strong’ holism

Quine is routinely perceived as having changed his mind about the scope of the Duhem-Quine thesis, shifting from what has been called an 'extreme holism' to a more moderate view. Where the Quine of 'Two Dogmas of Empiricism' argues that “the unit of empirical significance is the whole of science” (1951, 42), the later Quine seems to back away from this “needlessly strong statement of holism” (1991, 393). In this paper, I show that the received view is incorrect. I distinguish three ways in which Quine's early holism can be said to be wide-scoped and show that he has never changed his mind about any one of these aspects of his early view. Instead, I argue that Quine's apparent change of mind can be explained away as a mere shift of emphasis.     

试比较康德与黑格尔艺术观的辩证统一性

康德作为一个天才的美学家，具有创见性和敏感性地从艺术现象中考察出艺术的本质特征：主客观的辩证统一性。尔后，黑格尔在继承和批判前人经验的基础上，进一步丰富和完善了康德的理论，并使之体系化，从而奠定了其在西方美学史上的地位。比较二的联系与区别，更能显示他们的美学贡献和相承性。     

对制定《建筑法》的思考

针对当前建筑领域中存在法制建设不健全的情况,作者指出,制定旨在保证建筑事业健康蓬勃发展的《建筑法》应提上议事日程。同时提出了制定《建筑法》应遵循的基本原则,并对《建筑法》的内容作了初步设想。     

超弦理论与物质的统一性和可分性

超弦理论是粒子物理学在现阶段最有希望的一个发展方向,它向我们揭示出物质世界统一性及四种相互作用统一性的最新模式,指出了10~(-33) cm 是目前粒子可分的里程碑,同时指出超越这个限度去分割粒子的可能性及历史发展的必然性,宣告物质无限可分论是正确的、辩证的,不可分是锗误的、形而上学的.     

用平均连续模给出扰动单位根上插值算子的平均逼近阶

考虑在单位圆内有界解析且在单位圆周上Riemann可积函数中函数在两类扰动单位根上Lagrange插值多项式平均逼近此函数，得到了用平均连续模来刻划这个逼近阶的结果。指出了，无论从逼近的阶或从扰动性来说，都不能再改进。最后还对函数有高阶导数时给出逼近阶以及Hermite-Fejer插值多项式的逼近阶。因此，无论从函数类的广泛性，从阶的估计以及从振动性来看都对以往的工作作出了本质上的改进。
