PRINCIPLES AND PARAMETER DESIGN FOR AC-DC THREE-DEGREE FREEDOM HYBRID MAGNETIC BEARINGS

Chinese Journal of Mechanical Engineering 2006年第4期19卷 534-539页

作者： zhu Huangqiu XIE zhiyi zhu Dehong School of Electrical andInformation Engineering Jiangsu UniversityZhenjiang 212013 China

To simplify the mechanical structure, decrease the overall system size of the 3-degree freedom axial-radial magnetic bearings and reduce the manufacturing costs as well as operating costs, an innovated AC-DC 3-degree freedom hybrid magnetic bearing is proposed, which is driven by a DC amplifier in axial direction and a 3-phase power converter in radial directions respectively, and the axial and radial bias magnetic fluxes are provided with a common radial polarized permanent magnet ring. The principle producing magnetic suspension forces is introduced. By using equivalent magnetic circuit method, the calculation formulas of magnetic suspension forces and the mathematics models of the system are deduced. Nonlinearities of suspension forces and cross coupling between different degree freedoms are studied further by calculating the suspension forces at different displacements and control currents to validate the feasibility of the mathematics model. Then based on the mathematics models of the bearing, a control method of this novel bearing is designed. Lastly, the methods on parameter design and calculations of the bearing are presented, and an applicable prototype is simulated to analyze the magnetic path by using finite element analysis. The theory analysis and simulation results have shown that this magnetic bearing incorporates the merits of 3-phase AC drive, permanent magnet flux biased and axial-radial combined control, and reduces overall system size and has higher efficiency and lower cost, This innovated magnetic bearing has a wide application in super-speed and super-precision numerical control machine tools, bearingless motors, high-speed flywheels, satellites, etc.

International Journal of Technology Management 2013年第4期 104-106页

作者： zhiyi zhu Yunnan Provincial Institute for Ethnic Studies Yunnan University of NationalitiesKunmingYunnan650031 China

For a nation, culture is not only the promotion and enhancement to the national spirit and the realm of life, but also an essential content and indispensable support force to achieve economic development, it is the important cause and prominent of the overall strength and the main carrier and specific embodiment of a nation＇s ＂soft power＂, besides, it also represents the degree of civilization, level of development and height of this nation. Culture and cultural industry endow with the modern culture with new meaning, it requires that at the time we achieve the prosperity and development of culture, we must actively explore and operate a scientific mechanism which is most able to release the energy of the culture and play cultural efficiency, and then develop the industrial pathway of the cultural. Cultural industry is a little different from the general industry. This causes the special natm-e of the cultural industry which is different from other industries. Different water and soil raised different people, inheriting national culture and developing cultural industry can be described as the unity of the three ones.

乡村振兴战略的实施离不开完善的顶层法律制度设计的规范、保障和引领。改革开放以来,我国的"三农"领域立法虽已取得较快发展,但随着城镇化与农业、农村现代化进程的加快,在乡村振兴背景下,现有立法在回应乡村发展与社会转型所面临的新问题时仍显不足。因而,乡村振兴立法需要在修正现行基础立法不足、重塑"三农"法律体系以及克服过分依赖政策推进"三农"领域改革的弊端等方面发挥重要作用。同时,在制定有关乡村振兴的统一立法时,应当遵循纲领性与可操作性并重、坚持农民主体地位以及科学、民主、依法立法等原则。一方面,既要注重构建乡村振兴的基本组织架构及法律制度框架,又要明确相关措施的实施标准、程序和监督问责机制;另一方面,应当以实现农民主体地位、促进农民全面发展为依归,强化立法对农民平等参与及发展权利的保障。

开发新型纯碳水化合物燃料作为新能源时,必须预测和筛选纯碳水化合物的物理性质,从而找到可能合适的化学物质,然而由实验来逐一确定大量分子的物理性质既耗时又昂贵。研究发现,运用人工智能网络—定量构效关系(ANN-QSPR)算法来建立纯碳水化合物物理性质的计算模型可以起到事半功倍的效果。基于DIPPR 801数据库中的纯组分性质和DragonX软件包计算了相应碳水化合物的分子描述符,所构建的模型结合了定量构效关系(QSPR)和两层前馈人工智能网络(ANN)。由此建立了多个全面而可靠的模型来预测新型纯碳水化合物燃料的各种物理性质,包括正常沸点、闪点、燃烧焓、蒸发焓、液体密度、表面张力、液体的黏度和熔点等。为了提高模型中数据集之间的一致性,还引入了主成分分析法(PCA),以进一步消除分子描述符值的维数。另外,通过共识建模进行交叉验证,减少了不确定性的影响,提高了模型的预测精度。

公职人员处分制度的完善与否直接影响权力监督的效能与反腐工作的权威。《政务处分法》确立的“政务处分”与任免机关、单位“处分”并行的双轨惩戒制度,并非只是一种基于立法技术考量作出的概念调适及处理,须从构建更加丰富且立体化的公职人员惩戒体系、提炼构造出功能互补的惩戒法体系结构和实现精准监督三个层面去认识双轨惩戒制度的构造优势与生成逻辑。同时,虽然二元处分并行的制度在强化外部监督、促进监督全覆盖等方面取得了突出成效,但从制度的执行情况看,并行的两套处分体系并未真正实现“无缝衔接”,双轨惩戒制度仍面临两类处分适用失衡与监察机关对任免机关、单位实施处分的行为“再监督”乏力等问题。可通过借鉴“无缝隙组织”理论,从实现内外部惩戒的无缝衔接、权限划分的无缝闭合以及惩戒实施后的无缝隙管理三方面入手对双轨惩戒制度进行“再造”,使两类处分从相对割裂、各自为战的状态向“无缝隙”的惩戒监督体系转变。
