Editorial.

Psychology, Public Policy, and Law focuses on the links between psychology as a science, relevant information derived from related disciplines as sciences, and public policy and law. It will publish articles that (1) critically evaluate the actual and potential contributions of psychology to public policy and legal issues, (2) assess the desirability of different public policy and legal alternatives in light of the scientific knowledge base in psychology, (3) articulate research needs that address public policy and legal issues for which there is currently insufficient theoretical and empirical knowledge, and (4) examine public policy and legal issues relating to the conduct of psychology and of related disciplines where relevant to psychology. The goals for the journal are to (1) provide a multidisciplinary forum for scholarship and interchange relevant to the mission of the journal, (2) provide a forum for the publications of comprehensive, scholarly articles that critically consider theoretical, conceptual, and doctrinal issues or that critically review the literature on topics relevant to the mission of the journal, and (3) provide a forum for the publication of comprehensive, scholarly articles that report the results of programs of research or large-scale empirical studies relevant to the mission of the journal. This particular issue provides a forum for critical discussion of the implications of using a social science amicus brief in court cases. It also demonstrates the opportunity that this journal will provide to social scientists to critically evaluate their colleagues' work when those colleagues attempt to offer their science and opinions in the legal or public policy arenas. Finally, this issue reflects the journal's desire to be a flexible forum for scholarly interchange. Rather than always publishing articles that are relatively independent of each other, the journal will also publish issues devoted to a single theme (as occurred in the first issue of this volume), and, as in the case of this issue, to interchange about one theme when it is appropriate for advancing the field.

超声波对硫酸钡结垢影响规律研究

试验结果表明,超声波技术在集输管线和计量站应用中,能够满足在线运行的工况要求,具有很好的防垢与除垢效果。近些年,我国在超声波防垢和除垢技术领域取得显著的成就,该技术具有重要的科研价值和应用前景。其中,超声波的空化效应、活化效应、剪切效应可以有效的除垢防垢。近年来,研究超声波对碳酸钙结垢影响规律的文献比较多,但是超声波对硫酸钡结垢影响规律的研究较少,文章通过称重法和电镜粒度分析法研究超声波对硫酸钡结垢影响规律,为油气田有效的除去硫酸钡污垢提供一定的理论基础。

The development of a legislative framework for renewable energy and energy conservation

In the absence of any likely international law in the near future to impose comprehensive obligations on nations to take action to promote renewable energy or energy conservation, such action will be required at national level. This paper proposes a generic legislative framework for the control and development of all types of renewable energy and energy conservation. This framework can be adopted, subject to suitable modification according to local conditions and the prevailing legal system, by all interested nations. The framework would replace the piecemeal, ad hoc approach to law reform which characterises past developments in this area.     

基于比例风险模型的板级无铅焊点跌落寿命分析

文中进行了三组跌落高度下的焊点疲劳寿命试验,采用比例风险模型(PHM)分析跌落高度对焊点寿命分布的影响。PHM模型估计得到的焊点寿命期望(MTTF)及寿命失效概率密度与实验数据都能够较好的吻合,验证了模型的有效性。且由焊点跌落MTTF值随高度变化曲线可看出,当跌落高度略大于0.6m时焊点MTTF值都小于10次,表明无铅焊点对冲击载荷非常敏感。最后用估计得到的寿命期望结合Miner准则得到板极无铅焊点跌落寿命损伤累积模型。
