定规则是输出理性,而讲情理则是努力弥补“无恨亦无爱”的理性缺陷,非人格化与人格化的治理过程事实上已构成了治理工具的两面性。基于传统与现代交织的乡土特色,需要在治理有效的原则下融合规则与情理,形成规则寓以情理的中国特色乡村治理现代化模式。规则是治理普适性的政策供给与制度支撑,情理是地方性知识储备和乡土德治的基本经验。规则寓以情理作为中国特色乡村治理现代化模式,其内生于中国社会的乡土特质,更是规则与情理在基层治理活动中彼此耦合的结果呈现。新时代中国特色乡村治理效能的提升,需要深化治理有效的实践内涵以明晰其价值指向、推动规则的引导性转型以拓展其发展空间、培育乡村社会情感资源以厚植其内生动力。

Atomized, pre-alloyed Ti-24Nb-4Zr-7.9Sn （wt%） powder was used to fabricate solid, prototype components by electron beam melting （EBM）. Vickers microindentation hardness values were observed to average 2 GPa for the precursor powder and 2.5 GPa for the solid, EBM-fabricated products. The powder and solid product microstructures were ex.mined by optical and electron microscopy. x.ray diffraction analyses showed that they had bcc β-phase microstructure. However, it was found by transmission electron microscopy that the EBM-fabricated product had plate morphology with space -100-200 nm. Although the corresponding selected area diffraction patterns can be index.d by β-phase plus α＂-martensite with orthorhombic crystal structure, the dark-field analyses failed to observe the α＂-martensite. Such phenomenon was also found in deformed gum metals and ex.lained by stress-induced diffusion scattering due to phonon softening.

光学精密工程 2005年第5期13卷 570-574页

作者： HUANG Wen-hao x.NG hao Department of Precision Machinery and Precision Instrument University of Science and Technology of China HeFei 230027 China

A new type of three-finger micro-tweezer driven by electro-static force was developed for stable manipulation and assembly of micro devices. The whole system consists of micro-tweezers and a specially designed high frequency AC power supply. The free end of the fingers closes and opens with the increase and decrease of the voltage. The tweezers can grasp and manipulate micro objects at size from 30～100 μm. A quantitative simulation method based on boundarx.element method(BEM) and equation of energy conservation is introduced to analyze the non-linear behaviors of the tweezer closure. The simulation results agree well with the ex.erimental data.

宋夏沿边蕃部是北宋实施“禁盐制夏”的重要关注对象。太宗时期,北宋未认识到蕃部为己所用的军事价值,故禁盐针对的是蕃部整体。真宗、仁宗时期,北宋重视熟户蕃部防御西夏的作用,“禁盐制夏”转而针对生户蕃部。北宋禁盐对象改易与宋夏军事局势变化有关,体现了北宋实施策略的灵活性。

Nano-scale Tb-incorporated apatite （nano-Tb-AP） particles with different Tb contents （Tb/（Tb＋Ca）） of 0%, 5%, 10% and 20% were synthesized through a simple wet chemical method in this study. The crystal structure, thermal stabilities, chemical groups, crystal morphologies and crystal sizes of the nano--Tb-AP particles were characterized by x.ray diffraction （x.D）, Fourier transform infrared spectroscopy （FTIR）, and transmission electron microscopy （TEM）, respectively. It was found that lattice constants, particle sizes, crystalline and thermal stability varied with the doped Tb contents. With the increasing of Tb content, the lattice constants, particle size, length/diameter ratio, crystalline and thermal stability of nano-Tb-AP gradually decrease. Especially, almost all the 20%Tb-AP nano particles had been decomposed at 1200 ℃ while only a few of the decomposed products （β-TCP） were detected in the Tb-free nano apatite powders： This kind of nano-scale Tb-incorporated apatite ex.ibits an ex.remely potential clinic application because it integrates both the ex.ellent biological functions of Tb element and apatite in human body.
