飞灰冲蚀条件下材料抗磨性能的试验研究

本文首先综述了国内外学者在研究塑性材料耐冲蚀磨损性能方面所取得的主要成果,并在专门建立的灰磨试验台上,对电站燃煤锅炉对流受热面常用材料20号钢、12Cr_1MoV合金铜以及铜、铝四种塑性材料进行了耐飞灰冲蚀磨损性能的试验研究。提出用材料的体积磨损率来定义材料的耐冲蚀磨损性能系数。并用它表征塑性材料的抗磨性能。该系数可直接应用于计算燃煤锅炉对流受热面的安全烟速。     

古籍整理与方言的关系

本文分两个部分：第一部分讨论了古籍中因方言的存在而造成了异文和疑难词语的问题；第二部分讨论了古籍训诂应该重视方言的研究成果的问题。总之，本文旨在论述古籍整理与方言（包括古代和现代）研究的重要关系，不重视０方言研究的成果，就难以很好地做好古籍的校勘和训诂工作。

论香港地权法律制度的基本特点

作为地权制度核心的土地所有权制度,香港既没有承袭中国封建地主私有制,也没有效仿英国,而是根据自身的特殊性,建立了土地使用权与所有权相分离、土地只租不卖的基本制度。这个制度决定了港府在土地处置中拥有双重身份和权力,从而使土地发展利用的计划调节与市场调节得以比较完善的结合,为土地的经济、社会和环境效益全面实现提供了法律保障。香港经济与社会的发展和繁荣受惠于香港的地权法律制度。因此,分析研究香港地权法律制度,认识其基本特点,对“一国两制”的实现和借鉴香港经验,改革与完善我国地权法制都有相当价值。     

浅谈唐代音乐诗

Applying Image Norms Across Super's Career Development Stages

D. E. Super's (1957) theory of career development has long been of interest to careers researchers (M. Savickas, 1994; S. C. Whiston & B. K. Brecheisen, 2002). Its insightful illustration of career stages has made it widely applied by careers practitioners. Image norms may influence the career decisions and developmental tasks inherent in each stage. An image norm is the belief that individuals must present or possess a certain image, consistent with occupational, organizational, or industry standards, in order to achieve career success. Understanding the effects of image norms across D. E. Super's (1957) career stages has important implications for individuals, organizations, and career counseling professionals.

液相色谱串联质谱检测鳗鱼中四种氟喹诺酮残留

建立了液相色谱/串联质谱法测定鳗鱼中恩诺沙星,环丙沙星,诺氟沙星,氧氟沙星的方法。对分离和检测这四种兽药残留的液相色谱条件、质谱条件、样品前处理方法等作了详细的研究。用乙腈萃取样品中的残留物,在氮气保护下将萃取液浓缩干,加流动相1.0mL溶解残渣,正己烷液液萃取,弃上层液,下层溶液用作液相色谱分析荧光检测或质谱检测。在鳗鱼样品中添加四种残留物,添加浓度分别为0.01,0.050和0.100mg/kg,平均回收率(n=6)在70￣84.3%之间,相对标准偏差为3.0%～6.3%。     

关于构建和谐的社会利益协调机制的思考

日益加剧的社会利益分化和利益矛盾,内在地要求我们必须切实构建起和谐的社会利益协调机制。构建和谐的社会利益协调机制,要承认和尊重社会物质利益的差别,要坚持以公正的原则处理各种利益关系。当前,必须要改变过去协调利益矛盾政策滞后的状况,颁布切实有效的、和谐的协调利益矛盾的政策;要构建和谐的利益表达与实现机制;要实现社会利益调节法治化;要建立和谐的社会利益导向机制。     

Coping Trajectories from Adolescence to Young Adulthood: Links to Attachment State of Mind

The objective of this study was to examine the links between coping and attachment. In a longitudinal study of 112 participants, coping behavior was assessed at five points in time during adolescence (starting at the age of 14 years) and early adulthood. In addition, at the age of 21 years, state of mind regarding current and earlier attachment experiences was assessed by employing the Adult Attachment Interview (AAI). In both adolescence and early adulthood, differences in coping styles were found to be related to differences in attachment. Individuals classified as secure dealt with their problems more actively by using their social network during adolescence and at the age of 21 years. Both secure and dismissing individuals used more internal coping than those with a preoccupied state of mind. Latent growth curve modeling revealed that differences in active and internal coping between secure and insecure individuals applied to the rate of change in these coping styles between 14 and 21 years, with participants in the secure group showing much steeper growth in both coping styles. Only minor differences were found with respect to withdrawal as a coping style. The results represent first evidence that coping trajectories during adolescence and young adulthood are linked with attachment state of mind.
