《管子》杂糅各家学说,内容极为宏富庞杂,全书主要以“道法”为纲要,以“法治”为核心,尤其是“以法治国”思想注生重法治而不否定道德教化,倡导礼义廉耻而拒绝人治学说,深邃精湛,独具特色。《管子》的法治思想主要体现在其对法的特征、法的作用、法的制定、法的推行、德教与法并重诸方面的论述中。  相似文献

关于第二人称是否存在的争论,实际源于对人称概念界定的分歧,也就是以“观察点“为人称本质,还是以“称谓“作为人称标志的问题.其实“观察点“和“称谓“在研究文学作品时各有自己的功能用途,也有各自的适用范围.鉴于此,我们应该首先对人称的概念加以界定,然后使“观察点“和“称谓“各得其所.  相似文献

一、经营和管理的关系 我们常常习惯说企业的经营管理如何,但实际上“经营”和“管理”有着不同的内涵,二者之间既有联系,也有区别,相互之间有着密切的关系。  相似文献

Co1−x Zn x Fe2O4 ferrites were prepared by solid state reaction. The microstructure and performance were studied by X-ray diffraction, X-ray absorption fine-structure analysis and IRE-2 infrared radiant test. It is found that infrared radiance show a nonlinear change with x, exhibiting the infrared radiance of this material improved and the average radiance in the 8–14 μm waveband reached 0.91. The Co3+ and Zn2+ ions are found to occupy both tetrahedral and octahedral sites, and correspondingly, the fraction of Fe3+ ions in B-site decreases nonlinearly in ferrites. The lattice parameters are found to concern with Zn2+, and the activation energy deduces from crystal strain and crystal vibrate increases with content Zn2+. The redistribution of the Co3+ and Zn2+ ions between tetrahedral and octahedral sites is related to the providing a selective tetrahedral and octahedral sites infrared radiance of Co1−x Zn x Fe2O4 ceramics with increasing x.  相似文献

Fe doped In2O3 samples (In1−x Fe x )2O3 (x=0, 0.05, 0.1, 0.2 and 0.3) on glass substrate were prepared by sol-gel method. The XRD results demonstrate that the solubility of Fe ions in In2O3 matrix is around 20%, above which impurity phase can be observed. The transmittance of the samples with x=0, 0.05, 0.1 and 0.2 are above 80% in the visible region while the transimittance of the glass is 90%. The transmittance curves slightly red-shifts as x increasing. All of the samples except x=0 are ferromagnetic at room temperature. The highest saturation magnetization moment is reached in the sample x=0.2 with 330 emu/cm3, and the coercive force is 169 Oe which is also the largest in our samples. The results indicate that the addition of Fe ions could tune the structure, the ferromagnetism and optical property in the In2O3 matrix.  相似文献

From the perspective of growth units, the growth mechanism of Mg2(OH)2CO3·3H2O whisker is investigated in this paper. Results show that the growth morphology of Mg2(OH)2CO3·3H2O whisker is consistent with the model of anion coordination polyhedron growth units. The growth solution Raman shift of Mg2(OH)2CO3·3H2O was monitored using Raman spectroscopy. The growth units are [Mg-(OH)4]2- and H2CO3. The growth process of Mg2(OH)2CO3·3H2O whisker is as follows: growth unit [Mg-(OH)4]2- first incorporates into the larger dimension [Mg-(OH)4] n 2- , then the [Mg-(OH)4] n 2- combines with H2CO3 into a linear skeleton Mg2(OH)2CO3 in the same line. Mg2(OH)2CO3 combines with H2O by hydrogen bonds and ultimately transforms into Mg2(OH)2CO3·3H2O whisker. Magnesium carbonate whiskers have a layered structure, each of which is made of magnesium, carbon, oxygen, with H2O in between each layer. When skeletons are superimposed within the same plane as a parallelepiped one, they grow into solid cuboid-shaped whiskers. When the parallelepiped skeletons planes combine with each other through the cascading links, they grow into hollow cylindrical whiskers.  相似文献

从劳伦斯作品《儿子与情人》和《查泰莱夫人的情人》入手分析劳伦斯的性爱观,认为在道德沦丧、人性扭曲的社会希望性爱来治愈社会问题是不现实的;但劳伦斯强调对人类本性、精神与心灵的关注和交流,始终如一地热爱、崇拜和讴歌积极进取的生命的精神是值得赞扬与肯定的。  相似文献

Al70−X Si30Mn X (X=0, 3, 5, 7, 10, mol%) ribbons were prepared by melt spinning. A supersaturated solid solution of Si and Mn in fcc Al and some microstructures consisting of nano grains were obtained. Some alloys with nano-sized grains exhibited high discharge capacities and favorable cycle properties. The capacity of more than 400 mAh/g could be obtained in melt-spun Al67Si30Mn3 alloy after 20 cycles and more than 300 mAh/g after 40 cycles. Li/Si and Li/Al compounds in the anodes of pure Al and pure Si were not detected in Al-Si-Mn alloys inserted by Li. It is considered that the formation of the supersaturated solid solution and refinement of microstructures have prevented the alloys from the forming the compounds with superfluous Li. As a result, the electrochemical properties have been improved. Supported by the National Natural Science Foundation of China (Grant No. 50371066)  相似文献

A series of SiO2/β-Zn4Sb3 core-shell composite particles with 3, 6, 9, and 12 nm of SiO2 shell in thickness were prepared by coating β-Zn4Sb3 microparticles with SiO2 nanoparticles formed by hydrolyzing the tetraethoxysilane in alcohol-alkali-water solution. SiO2/β-Zn4Sb3 nanocomposite thermoelectric materials were fabricated with these core-shell composite particles by spark plasma sintering (SPS) method. Microstructure, phase composition, and thermoelectric properties of SiO2/β-Zn4Sb3 nanocomposite thermoelectric materials were systemically investigated. The results show that β-Zn4Sb3 microparticles are uniformly coated by SiO2 nanoparticles, and no any phase transformation reaction takes place during SPS process. The electrical and thermal conductivity gradually decreases, and the Seebeck coefficient increases compared to that of β-Zn4Sb3 bulk material, but the increment of Seebeck coefficient in high temperature range remarkably increases. The thermal conductivity of SiO2/β-Zn4Sb3 nanocomposite material with 12 nm of SiO2 shell is the lowest and only 0.56 W·m−1·K−1 at 460 K. As a result, the ZT value of the SiO2/β-Zn4Sb3 nanocomposite material reaches 0.87 at 700 K and increases by 30%.  相似文献

Existence of [B3-O6]3− hexagonal ring growth unit in melt solution of β-BaB2O4 crystal was proved by the results of high temperature Raman measurements. A morphology evolution process of β-BaB2O4 crystal was observed by a high temperature in-situ observation device. The crystal morphology varied with the supersaturation of growth melt solution. The mechanism of β-BaB2O4 crystal morphology evolution was analyzed through the growth unit model.

A new composite adsorbent SiO2·xH2yCaCl2 which is composed of macro-porous silica gel and calcium chloride is introduced. In order to analyze its adsorption theory, adsorption and desorption isotherms, BET surface areas, pore volumes and average pore diameters of macro-porous silica gel and four composite adsorbent samples with different CaCl2 content are measured using SEM and Asap2010 apparatus. From the adsorption isotherms, desorption isotherms and lag loops, it can be deduced that the main pore structure in macro-porous silica gel and the new composite adsorbent have two shapes: taper with one top open and taper or hyperbolic taper with both ends open. Based on the analysis of pore diameter distribution and lag loop, a sketch map showing calcium chloride filled in pore of macro-porous silica gel is presented. The adsorption isotherms at 25°C are measured. Experimental results show that the new composite adsorbent can adsorb more water than common adsorbents (macro-porous silica gel, micro-porous silica gel and synthetic zeolite 13X). In the light of the results of pore structure, adsorption isotherms and lyolysis phenomenon are analyzed.  相似文献
