离子晶体外表面束缚极化子

本文计及表面光学声子的作用以及像电荷的作用,采用变分方法对一些材料外表面束缚极化子的基态能量和自陷能作了数值计算,并对结果进行了讨论,发现:对于Ⅰ—Ⅶ、Ⅱ—Ⅵ,Ⅲ—Ⅴ化合物的外表面,均可形成稳定的束缚极化子,且由于表面光学声子的作用,使这一杂质态更加稳定。     

Breaking the intergenerational transmission of child abuse: Beyond the mother-child relationship

Studies comparing abusive and non-abusive parents who were abused as children are reviewed to determine protective factors that may lead to a break in the transmission pattern. Non-abusers have several factors in common. For instance: they have extensive emotional and social support from significant others. they are aware of what happened to them as children and are openly angry about their abuse. and many of them received (psycho)therapy as adolescents or young adults. Discovering protective factors by which some parents overcome a family pattern of abuse is valuable in guiding both prevention and intervention efforts. A brief discussion of the influence of methodological variations of different studies on reported transmission rates precedes the review. Furthermore. attention is given to the underrepresentation of (abusive) fathers in theory as well as in research on child abuse. The effects of undervaluation of gender differences are discussed in terms of their importance in the occurrence and (breaks in the) transmission of child abuse.     

Theoretical consideration of effect of fishing mortality on growth and reproduction of fish populations

Summary An increase in fish mortality due to fishing can theoretically change the growth and reproduction of fish populations from the viewpoint of adaptation. We address the issue of how an iteroparous fish should convert surplus energy into somatic growth and reproduction at each age under given conditions of mortality. A model of life history, which maximizes the net reproductive rate using the discrete maximum principle, is improved employing a new relationship between body weight and surplus energy which we have recently proposed. The model is applied to the North Sea plaicePleuronectes platessa, for which it has been reported that the average length of young fish had increased whereas that of old ones had decreased for some decades. Although the model cannot directly explain the former phenomenon, the two phenomena can be interpreted as a change in the optimal life history due mainly to an increase in mortality.

能源教育：节约型社会建设的重要途径

节约型社会建设目标的提出,进一步对节能工作提出了挑战。加强节约型社会建设和提高节能工作的效果,从国外经验来看,能源教育是一个现实和有效的途径。本文从能源教育的必要性及国外能源教育的经验入手,提出了中国发展能源教育的若干建议。     

美国能源教育发展及其启示

美国从1980年启动了“美国能源教育开发”项目,从不同层面开展对国民的能源教育,由此构建了覆盖全国的能源教育体系,找到了应对能源危机的教育途径,在提高国民的能源意识、增强国民的节能技术和节能自觉性,化解能源危机等方面取得了显著成就。美国能源教育开发的经验值得我们借鉴。
