This is an article that validates Electron Cyclic Donate-Accept Catalysis Mechanism-ECDAM or Electron Orbital Deformation-Recovery Cycle Catalysis Mechanism-EODRM. In this paper, the influence of compact density, sintering temperature and time, vacuum degree, atmosphere and alloying element on the carbon dissolving rate into γ-Fe were studied. The experiment results have been reported. The way that the carbon is dissolved into γ-Fe was discussed. Gas phase composition and temperature play an important role on the carbon dissolving rate. The carbon gasification reaction is the determining step of dissolving carbon process. K2CO3, W and Mo are a catalysts, and their active size are K2CO3 > W > Mo. S and SiO2 are a poison, and their poison size are SiO2 > S. The experiment results are completely consistent with the original judgment of ECDAM.

创新的本质是人们根据自身的实际需要和价值取向,构思、实现客观世界可能产生但从未实际产生的物质客体、物质联系以及它们彼此之间的相互转化,并获得预期的成效,产生积极的社会效益。要创新,就要立足于自身的实际环境,就要有改变现状的冲动。国家、企业和个人都应该着眼于事物变化发展的必然性和规律性,从建立的事物之间可能发生但从未实际发生、符合自身价值取向的最切近的新联系入手,使创新成为一个形式上往复不断、内容上不断充实更新的延续过程,成为中华民族振兴的不竭动力。

在马克思那里,意识形态指对当时社会采取非批判和维护态度的思想体系。马克思认为意识形态具有统治阶级的统治性和对社会真实关系的遮蔽性。对马尔库塞而言,意识形态就是技术理性,技术在当代工业社会已经代替了传统的意识形态国家机器,而充当着新的意识形态的统治和辩护功能。马克思创造性地建立了科学的实践观,实践观是马克思的意识形态批判理论的最基本的观点,马尔库塞提出意识形态批判的最高诉求是解放爱欲。

广东自贸区自成立以来,虽然在推动粤港澳深度合作方面初见成效,但自贸区范围内的生产要素流动仍有阻碍,经济商业活动缺乏更大的自由发挥空间。为充分发挥粤港澳综合优势,更好地构建与国际接轨的开放型经济新体制,推动澳门经济适度多元发展和深化粤澳合作,建议将澳门部分自由港政策延伸到横琴,参照世界高水平的开放形态和国际通行规则改革横琴现有体制,突破旧有行政区域划分造成的制度“藩篱”,以政策创新推动澳门和横琴的体制机制贯通、变通和融通,并在广泛调研的基础上提出具体方案建议,为解决内地与澳门存在的制度差异,形成生活和营商环境逐步趋同的“粤澳深度合作区”提供参考。

Acta Metallurgica Sinica(English Letters) 2017年第3期30卷 272-279页

Intrinsic stacking-fault energy is a critical parameter influencing the various mechanical performances of aus- tenitic steels with high Mn concentrations. However, quantitative calculations of the stacking-fault energy （SFE） of the face-centered cubic （fcc） Fe, including the changes in concentrations and geometrical distribution of alloying atoms, cannot be obtained by using previous computation models. On the basis of the interaction energy model, we evaluated the effects of a single alloying atom （i.e., Mn, A1, Si, C and N）, as well as its aggregates, including the Mn-X dimer and Mn2-X trimer （X = A1, Si, C and N） on the SFE of the fcc Fe via first-principle calculations. Given low concentrations （〈10 wt%） of alloying atoms, dimers and trimers, theoretical calculations reveal the following：（1） Alloying atom Mn causes a decrease in the SFE, whereas A1, Si, C and N significantly increase the SFE; （2） combination with other alloying atoms to form the Mn-X dimer （X = A1, Si, C and N） exerts an effect on SFE that, to a certain extent, is close to that of the corresponding single X atom; （3） the interaction between Mnz-X and the stacking fault is stronger than that of the corresponding single X atom, inducing a significant increase in the SFE of fcc Fe. The theoretical results we obtained demonstrate that the increase in SFE in high-Mn steel originates from the synergistic effect of Mn and other trace alloy atoms.

Background The pathogenesis of biliary atresia (BA) is associated with an inflammatory process involving the biliary tree. This study aimed to investigate the association of T-helper cell cytokine levels with age in patients with BA. Methods Twenty-eight patients with BA were divided into three groups according to their age (< 2 months, 2–3 months, and ≥ 3 months). All the patients underwent Kasai portoenterostomy. Blood samples were collected from the patients pre-operatively, and the liver tissue specimens were obtained during surgery. We detected serum levels of interleukin (IL)-1β, IL-12p70, interferon (IFN)-γ, IL-6, IL-10, and transforming growth factor (TGF)-β1 and liver expression of IL-1β, IL-6, and TGF-β1. Results The serum levels of IL-1β, IL-12p70, IL-6, and IL-10 in patients aged ≥ 3 months were significantly higher than those in patients aged < 2 months. There were no significant age-related differences in the IL-1β, IL-6 and TGF-β1 expres-sion levels in the liver tissue of patients with BA. Conclusions The serum levels of IL-1β, IL-6, IL-10 and IL-12p70 showed significant age-related differences in patients with BA. Interpretation of the role of cytokines in BA needs to take patient's age into consideration.
