梁启超用西方逻辑学思想来研究墨学,提出墨家著作里也有概念、判断和推理等理论.这种用<墨辩>里的一些概念来比附西方逻辑学理论的做法与梁启超的文化现有关.这种研究的积极意义在于促进了逻辑学在中国的早期传播,开了"中国逻辑史"研究之先河.其消极影响在于不利于逻辑学的进一步发展和深入研究,影响着当今一些学者对"中国逻辑史"的研究. 相似文献

南戏体制从宋元到明中叶,逐渐发生变化并趋于整饬。今人依据常见的元明南戏（传奇）剧本,以为从元代开始,南戏开场形式已经十分简练扼要,一概由末念诵一至二首词,这是一个误解。只是到了万历时期,文人创作讲求文采格律,才固定为简要的一词或二词形式。从南戏到传奇剧本,逐步走向分"出",开始时"折""出""节""套"皆用,宣德年间正式分"出",嘉靖年间开始列"出""目",万历以后趋于规整。 相似文献

论"原始的基本关系"--冯契关于辩证分析逻辑起点的一个重要思想 总被引：1，自引：0，他引：1
彭漪涟 《华东师范大学学报(哲学社会科学版)》2002,34(1):31-35
建构对象理论体系的逻辑分析起点是对象复杂整体中的"细胞"或"细胞形态",这是理论界长期以来的一个传统提法.冯契在其写成于上世纪80年代初的<逻辑思维的辩证法>一书中曾用"弄清一个领域里原始的基本关系"的提法来代替这一传统提法,这不仅是有充分理论根据的,也是符合现代科学发展的客观进程及其对方法论的需要的,是对辩证逻辑方法论原理所作出的一个新概括和新贡献. 相似文献

In this paper, we shall prove that the Marcinkiewicz integral operator #n, when its kernel Ω satisfies the L^1-Dini condition, is bounded on the Triehel-Lizorkin spaces. It is well known that the Triehel-Lizorkin spaces are generalizations of many familiar spaces such as the Lehesgue spaces and the Soholev spaces. Therefore, our result extends many known theorems on the Marcinkiewicz integral operator. Our method is to regard the Marcinkiewicz integral operator as a vector valued singular integral. We also use another characterization of the Triehel-Lizorkin space which makes our approach more clear. 相似文献

Using SnxTi1-xO2 as carriers, CuO/Sn0.9Ti0.1O2 and CuO/Sn0.7Ti0.3O2 catalysts with different loading amounts of copper oxide (CuO) were prepared by an impregnation method. The catalytic properties of CuO/Sn0.9Ti0.1O2 and CuO/Sn0.7Ti0.3O2 were examined using a microreactor-gas chromatography (GC) NO CO reaction system and the methods of BET (Brun- auer-Emmett-Teller), TG-DTA (themogravimetric and differential thermal analysis), X-ray diffraction (XRD) and H2-temperature programmed reduction (TPR). The results showed that NO conversions of Sn0.9Ti0.1O2 and Sn0.7Ti0.3O2 were 47.2% and 43.6% respectively, which increased to 95.3% and 90.9% at 6 wt% CuO loading. However, further increase in CuO loading caused a decrease in the catalytic activity. The nitrogen adsorption-desorption isotherm and pore-size distribution curve of Sn0.9Ti0.1O2 and Sn0.7Ti0.3O2 represented type IV of the BDDT (Brunauer, Deming, Deming and Teller) system and a typical mesoporous sample. There were two CuO diffraction peaks (2θ 35.5° and 38.7°), and the diffraction peak areas increased with increasing CuO loading. TPR analysis also detected three peaks (α, β and γ) from the CuO-loaded catalysts, suggesting that the α peak was the reduction of the highly dispersed copper oxide, the β peak was the reduction of the isolated copper oxide, and the γ peak was the reduction of crystal phase copper oxide. In addition, a fourth peak (δ) of the catalysts meant that the SnxTi1-xO2 mixed oxides could be reductive. 相似文献

Ml0.7Mm0.3Ni3.7Co0.7Mn0.4Al0.2 nanocrystalline hydrogen storage materials are prepared by melt-spinning(MS).X-ray diffraction is used for the measurement of the nanocrystalline size.Compared to the electrode of polycrystalline alloys,the property of activation MH9metal hydride)electrode of the alloys with nanometer scale became worse and the inital discharge capacity decreased.It may be ascribed to the decrease of the total amount of rare earth metals and the increase of oxygen on the surface from the analysis of components of the alloys.After heat-treatment,the electrochemical performance of MH electrode of as-spun alloys could be improved,which could be attributed to the alleviation of the lattice strain. 相似文献

Supersaturated solid solutions Fe1-xCx （0≤x≤0.9 ） of wide composition range have been prepared by mechanical alloying process. Nanocrystalline phase was formed for 0 ≤ x ≤ 0.67 and a large grain phase for 0.75 ≤ x ≤ 0.9. The large fraction of graphite volume puts off formation of nanocrystalline phase for high carbon content. In the large grain phase, magnetization follows simple magnetic dilution, and eoereivity He is mainly due to dissolution of carbon at grain boundaries. In the nanocrystalline phase the alloying effect of carbon is revealed by a distinct reduction of average magnetic moment. The increasing lattice constant with increasing carbon content is observed for x ≤ 0.5, suggesting that the high carbon concentration may enhance diffusion of carbon into the Fe lattice. It shows a discontinuity in the Hc variation with a grain size D of nanocrystalline phase. For small grain D below the critical value, Hc increases with D. For a large grain D, Hc decreases with increasing D. The solubility limit of carbon in a-Fe extended by nanocry- stalline phase formation is discussed. 相似文献
