通过思想史的考察,可以揭示马克思对黑格尔思辨哲学的批判在《黑格尔法哲学批判》和《巴黎手稿》中存在重要差异。由于其批判尺度的变化,这为马克思对黑格尔思辨方法的肯定和改造奠定了思想地基。以至在后来的政治经济学批判中,马克思... 详细信息

通过思想史的考察,可以揭示马克思对黑格尔思辨哲学的批判在《黑格尔法哲学批判》和《巴黎手稿》中存在重要差异。由于其批判尺度的变化,这为马克思对黑格尔思辨方法的肯定和改造奠定了思想地基。以至在后来的政治经济学批判中,马克思对黑格尔的思辨方法做了新唯物主义改造和科学应用。由此,马克思对黑格尔思辨哲学的批判存在理论上的限度,但正是对这种限度的自觉肯认为马克思建构科学的政治经济体系提供了方法论上的参照。

无形经济作为一种客观存在的经济事实,极大地改变了物质生活的生产方式,被称为“无资本的资本主义”。事实果真如此吗?在政治经济学批判的视域中,通过固定资本和资本有机构成的理论照射,无形经济的资本实质可以被揭示出来,并在有形与无... 详细信息

无形经济作为一种客观存在的经济事实,极大地改变了物质生活的生产方式,被称为“无资本的资本主义”。事实果真如此吗?在政治经济学批判的视域中,通过固定资本和资本有机构成的理论照射,无形经济的资本实质可以被揭示出来,并在有形与无形、主观能动性与经济客观规律、无形经济的消极影响(如加剧不平等)与积极效应(如社会上层建筑变革)等哲学视界上进一步对它予以审视,以期为中国式现代化的经济建设提供一种可资借鉴的理论资源和实践启示,有助于我们把握有形经济和无形经济的关系在生产实践中的边界,防止经济脱实向虚。同时,在无形经济发展中增强经济增长的内生动力,实现经济社会的高质量发展。

Gas metal arc welding, laser welding, and laser-metal active gas welding(MAG) hybrid welding methods were applied to WYS700 steel.Different welding procedures were performed and different welding technologies were compared.Macro metallographs of the welded joints were obtained, and the mechanical properties(such as tensile strength, bending property, and hardness) of the joints formed using the different welding technologies were determined.The results revealed that the joint of the WYS700 steel could be formed well through gas metal arc welding, laser welding, and laser-MAG hybrid welding.Furthermore, the softening of the welding heat affected zone can be effectively reduced to obtain good strength and plasticity by using a suitable welding procedure.Laser-MAG hybrid welding allows the realization of high efficiency and deep penetration for the welding of thick plates with specifications above 3 mm.

Using nerve guide conduits (NGCs) to promote the regeneration of PNI is a feasible alternative to autograft.Compared with NGCs made of single material,composite NGCs have a greater development prospect.Our previous research has confirmed that poly(D,L-lactic acid)/β-tricalcium phosphate/hyaluronic acid/chitosan/nerve growth factor (PDLLA/β-TCP/HA/CHS/NGF) NGCs have excellent physical and chemical properties,which can slowly release NGF and support cell adhesion and proliferation.In this study,PDLLA/β-TCP/HA/CHS/NGF NGCs were prepared and used to bridge a 10 mm sciatic nerve defect in 200-250 g Sprague-Dawley (SD) rat to verify the performance of the NGCs in vivo.Substantial improvements in nerve regeneration were observed after using the PDLLA/β-TCP/HA/CHS/NGF NGCs based on gross post-operation observation,triceps wet weight analysis and nerve histological assessment.In vivo studies illustrate that the PDLLA/β-TCP/HA/CHS/NGF sustained-release NGCs can effectively promote peripheral nerve regeneration,and the effect is similar to that of autograft.

Submerged arc welding(SAW) and gas metal arc welding(GMAW) experiments of Nb-bearing X80 steel were conducted with high-toughness wires.The inclusions in weld metals were analyzed in terms of their types and sizes.In GMAW,the inclusions are primarily Ti, Ca, Si, Al, and Mg compounds with no Nb and are generally less than 0.8 μm in size, whereas, in SAW weld, the inclusions are larger, mostly approximately 2-5 μm in size, and are cored with Ca and Ti, exhibiting obvious oxidation metallurgical features.The SAW joint was hot-deformed, and Nb-bearing nano precipitates were newly found in the weld metal through transmission electron microscopy, and Nb-free core-shell inclusion was found through scanning electron microscopy.The inclusions and precipitates were dispersed in or on the boundaries of acicular ferrite, contributing to acicular ferrite nucleation and grain refinement.

季节性冻土区土体的物理力学性质受干湿交替与冻融循环两种风化作用综合影响,开展单一冻融循环与干湿-冻融耦合作用下水泥改良粉细砂的UCS试验与剪切试验,并分析水泥延迟时间对土体物理力学参数的影响。试验结果表明:随着延迟时间的增大,水泥改良粉细砂的最大干密度先增大后减小,最优含水率先增大后趋于平缓再增大,延迟时间3 h时约为0 h时的70%;冻融循环3次后,随着延迟时间的增加,UCS值分别减小了-5.23%、5.15%、6.0%及6.32%,试样的UCS值、黏聚力整体减小,内摩擦角呈增大趋势;干湿-冻融循环作用下试样的各项参数均减小,先脱湿后吸湿路径下各项参数均比先吸湿后脱湿路径下略高。在不同风化作用下,试样的UCS值、黏聚力、内摩擦角均随延迟时间的增大而减小。研究结果可对季节性冻土区水泥改良粉细砂在施工及设计中的应用提供一定的参考。

A series of novel water soluble chitosan derivatives as gene vectors was synthesized. The delivery systems were tested for their ability to form complexes with plasmid DNA by utilizing agarose gel electrophoresis, particle size analysis, zeta potential measurement and scanning electron microscopy. Furthermore, cytotoxicity of chitosan derivatives and transfection efficiency of polyplexes were evaluated in vitro. The experimental results showed that the novel chitosan derivatives had lower cytotoxicity, good DNA condensation, and higher transfection efficiencies compared to chitosan in both 293T and HeLa cell lines. It was indicated that these chitosan derivatives were promising candidates for non-viral gene vectors.

Conductive polymers show great promise because of their electrical property based on bioelectricity in vivo. In order to search electro-activity materials which insure abduction of tissue, we synthesized conductive nerve conduits with poly-dl-lactic-acid(PDLLA) and tetra-aniline(TA). Preparation technology of TA was optimized, and the properties of the conduit were studied. RSC96 cell were used to investigate the toxicity and electrical stimulation effect. SD rats were used to assess biocompatibility in vivo. The results showed that the reaction ratio of 1:1, the reaction time of 2 h and the HCl concentration of 2 mol/L were the optimum conditions for synthesis of TA. The influence of TA content on the mechanical properties, hydrophilicity, conductivity and microstructure of the nerve conduit was evaluated. Cell and histocompatibility study showed PDLLA/TA possessed good biocompatibility. These results showed it had application values in tissue projects.
