路灯新型热管散热器散热研究

LED（light emitting diode）结温过高不仅会使光波波长漂移,还会使发光效率和寿命下降,为此设计了一种热管翅 片散热结构,并运用ANSYS Icepak热分析软件对该结构进行了参数化分析设计,得到了LED最高结温小于70℃时的最 优结构参数。同时建立了翅顶为恒温的数学方程,计算验证翅片温度分布,结果显示翅片温度分布相近,散热器整体温 度分布均匀,整体温差小于5℃。表明设计的热管翅片散热结构满足大功率LED路灯的使用要求。     

金朝初期春水纳钵之地的考察--兼考"冒离纳钵"与"莫力街古城"之谜

何谓"纳钵"?"纳钵"究竟为何种语言?其含义是什么?这些问题早被已故的辽金史的专家傅乐焕先生在<辽史丛考>一书中作了十分准确的回答."冒离纳钵"是金朝初年皇帝的春猎之所,在<金史><许亢宗奉史行程录>等书中均有记载.然而,这个非常重要的地名几乎被治<金史>研究者们所忽略,本文主要是从实地调查的角度,对"冒离纳钵"的地理位置进行了详细考证,提出"冒离纳钵"即今日哈尔滨市郊区的莫力街古城.     

槐树的实用功能与文化象征

槐树在文化史上的重要性有赖于其多种实用价值的开发利用。槐树的可燃功能使之成为“改火”之木,并确立了槐树的“阴树”身份。槐叶可以用作防暑之物,食槐成为古代文人的一种风雅。槐树的药用价值将之提升为仙方灵药,并将槐树引入了神仙境界。作为行道树的槐树则附着了多层政治寓意。宋代以后,在董永遇仙传说中,槐树承载了遇仙、生殖、富贵三层用意。     

An overview of programmes offered by shelters for street children in South Africa

This paper reports part of the findings from a 2014 audit of shelters for street children conducted in four provinces of South Africa. The paper focuses on the assessment of the types, structure and implementation of the programmes, as well as on the adequacy of resources necessary for implementing the programmes. The overall picture that emerged from the assessment was that all shelters draw on a comprehensive and enabling legislative and policy framework to offer some elements of developmental, therapeutic and recreational programmes at the early intervention level. Overall, however, the implementation of the programmes does not effectively take into consideration the varied and interconnected factors that, within and across multiple social systems, impel children to the streets. It was thus apparent that the programmes do not adequately address the risks and opportunities of street children in South Africa, specifically within the eco‐developmental framework. Recommendations are offered for social work policy and practice to further enhance the quality and impact of programmes offered in the shelters.     

Access to social services as a rite of integration: Power,rights, and identity

Access to social services is a multifaceted and multifactorial process, involving social policy lines, services organization, and professional front line practices. It appears to have a crucial role in how personal social services work: depending on the way the process is handled, access to social services could provide a bridge to an inclusive and solidarizing community or worsen discrimination and marginalization. Many underline how studying the actual encounters between citizens and practitioners can provide a privileged site to highlight the interconnections between the abovementioned factors. This is the focus of our research that explored access in a specific Italian region using a case study strategy. After a pilot study, the main points of access to social services were identified, and three units were selected as best examples of different approaches. The three units were explored using mainly qualitative methods inspired by ethnography. We were able to gain in depth understanding of three cultural approaches to access, defined as the “ethical duty,” the “good organization,” and the “professional approach” and reach an in‐depth understanding of their impact on access. There is a vast literature on the power of street‐level bureaucrats, seen as similar to gatekeepers. However, our research suggests that specific organizational cultures also play an important part: different organizational cultures may impact the implementation of local social policy, the organizational procedures, and social workers' practices.

《暗店街》中的当代法国人形象剖析

帕特里克·莫迪亚诺（PartricModiano）在法国当代文坛中占有重要地位,其龚古尔文学奖获奖作品《暗店街》以“海滩人”的形象表现了法国人的“局外人”、“流浪者”的特点,这与20世纪以来的现代派文学一脉相承,与之不同的是作品还表现了当代法国人执着寻根的特点。这种“流浪者”与“寻根者”相互矛盾的特点,说明了莫迪亚诺笔下的当代法国人是“执着寻找自身踪迹的“海滩人”。莫迪亚诺笔下的这种新的法国人的形象,是其对法国及世界当代文学的新贡献。

朝鲜燕行使与中国琉璃厂

朝鲜李朝的燕行使和中国明清时期的琉璃厂有着千丝万缕的联系。朝鲜好多名人学士回国后都在著述里留有琉璃厂的记录,而燕行使与中国学者在琉璃厂结下的深厚友谊也在当时和后世传为佳话,由此可以看出,燕行使与琉璃厂的结缘对朝鲜吸收先进文化起到了重要作用。
