一种求Ramsey数的命题演算法

首先在矩阵中用谓词描述“含Kn”和“含－↑Km”，然后通过命题演算法逐行求出不含Kn也不含－↑Km的矩阵（aij)j=i 1,…，l^i=1,2,…l-1，若对于l≤r－1有这样的矩阵，而对于l=r却没有，则r为Ramsey数。     

冲积河流能量耗散理论的研究

引入河流熵概念,根据冲积河流发展趋向性法则,从系统角度探讨了冲积河流系统自我调节机制及河流能量分配耗散特点,以变化原理为基础,推了河流系统能量耗散规律;结合人类活动对河流的干扰,研究分析了河床调整自由与河流能量分配,耗散间的制约关系。文中还指出了近年来黄河内蒙河段河床活动性增强的原因,并给出了该河段曲折率的变化规律。

Hermann Cohen's Das Princip der Infinitesimal-Methode: The history of an unsuccessful book

This paper offers an introduction to Hermann Cohen's Das Princip der Infinitesimal-Methode (1883), and recounts the history of its controversial reception by Cohen's early sympathizers, who would become the so-called ‘Marburg school’ of Neo-Kantianism, as well as the reactions it provoked outside this group. By dissecting the ambiguous attitudes of the best-known representatives of the school (Paul Natorp and Ernst Cassirer), as well as those of several minor figures (August Stadler, Kurd Lasswitz, Dimitry Gawronsky, etc.), this paper shows that Das Princip der Infinitesimal-Methode is a unicum in the history of philosophy: it represents a strange case of an unsuccessful book's enduring influence. The “puzzle of Cohen's Infinitesimalmethode,” as we will call it, can be solved by looking beyond the scholarly results of the book, and instead focusing on the style of philosophy it exemplified. Moreover, the paper shows that Cohen never supported, but instead explicitly opposed, the doctrine of the centrality of the ‘concept of function’, with which Marburg Neo-Kantianism is usually associated.
