The microstructures and magnetic properties of Ce-32.15Co_49.36Cu_9.84Fe_9.65 magnet sintered at the temperatures ranging from 1005 to 1105 °C were investigated. The results on scanning electron microscopy and X-ray diffraction analysis indicate that the remanence B r of the magnets is mainly influenced by the degree of the easy-axis orientation when sintering temperature is less than 1085 °C, the rapidly increasing amount of the secondly phase (5:19 phase) gives rise to the deterioration of the magnetic properties of the magnet above 1085 °C. Moreover, it is found that intrinsic coercivity H ci is strongly related to the content of copper in the matrix of the sintered magnets. The optimal sintering temperature is located in 1025~1055 °C, the corresponding magnetic properties of the magnets are B_r =0.685T, H_(ci) =350kA·m^-1 , and maximum energy product (BH)_m =85.6 kJ·m 3 .

作者： zhu yikun Law School and Intellectual Property School Ji 'nan University

The operating processes of boards of directors are delicate and complex, so corporate legislation cannot simply equate board structure law with board governance law. It is therefore necessary to start from China＇s actual conditions and grasp the operating processes of Chinese boards with a sober appreciation of the irrational elements in their operating mechanisms. Board governance has entered a new stage of institutionalization, and the law should shift from its emphasis on structure to give equal attention to structure and process in optimizing institutional structure. In the construction of board operating mechanisms, we should treat differently such ＂living laws＂ as customs, experiences and traditions, give full play to the functionality of boards＇ strategic choices, and provide legal regulation of irrational elements, so as to distinguish between different roles, develop consensus, select strong points and improve efficiency. We should build control over board operational procedures, improve the system of functional allocation, correct assessment mechanisms, develop a mechanism for judicial scrutiny of the affective relationships in society and curb such behavioral tendencies as relational identity, structural bias and group polarization, with a view to controlling such ＂living laws＂ within the framework of the basic values and principles of board governance.

论董事问责的诚信路径

董事经营决策的尊重审查模式契合了适应性效率的要求,有利于鼓励董事进行尝试性试验。但是,在商事判断规则作用下,董事问责需原告负担严苛的举证责任,董事决策审查形式化以及注意标准的不确定性,使得注意义务几乎被掏空,介于重大过失与恶意之间的董事失信情形往往逃脱法律责任。诚信路径不仅是问责空隙的填补机制,也是克服股东与董事之间信息不对称问题的重要机制。20世纪90年代以来董事问责的司法实践催生了诚信路径,诚信概念亦因创造性转化而获得新生,其行为标准日益明晰,司法审查可操作性增强。我国可通过《公司法》的司法解释界定诚信的行为标准,将故意让公司违法、不坦诚告知、滥用职权和严重失职纳入其涵摄范围,从而引入诚信问责路径。

RANKL/RANK/OPG信号通路是维持骨吸收和骨形成平衡的重要信号轴, 近年来研究发现此信号通路不仅分布于骨骼, 还分布于肝脏、肌肉、脂肪组织、胰腺等可能影响糖代谢的组织中, 阻断RANKL/RANK/OPG信号通路可能保护胰岛β细胞功能, 其次, RANKL可通过诱导米色脂肪细胞分化、增加能量消耗来改善胰岛素抵抗。目前, RANKL对糖代谢的调节作用仍存在争议, 本文就现有的研究结果作一综述, 为使用RANKL抑制剂治疗糖尿病合并骨质疏松症提供参考依据。

不以营利为目的的公司型社会企业已然存在,而中国公司法上并没有其容身之处。现行公司法以传统商事公司为目标对象,并未将社会企业纳入其规范视野。《民法典》构建的营利与非营利二分法法人体系,将公司性质限制在营利法人范围之内,造成一定程度的法律体系冲突。为了推动高质量发展,为社会企业利用公司框架和市场机制实现社会目的,需要对《民法典》相关条款的文意进行目的解释。公司法修改亦应走出公司是仅以营利为目的,且须遵守股东利益最大化原则的路径依赖。通过提升现有公司法规的包容性,制定专章或专条,将公司型社会企业纳入公司法,建构相应的社会目的实现机制,为社会目的公司高质量发展提供适宜的组织法保障。
