Dear editor,Active phased arrays are widely used in radar and communication systems due to their characteristics such as rapid wave beam steering, agile beamforming, and spatial power synthesis. The phased-array system contains a large number of elements. Three critical components in each element are precise amplitude control, precise phase control, and signal amplification.

The Journal of Human Rights 2009年第4期8卷 13-15页

作者： sun shiyan head of the Research Officeof International Public Law under the ChineseAcademy of Social Sciences and a research fellowof the International Law Study Center.

There has been much discussion in the recent decade on the universality or particularity or relativism or on the relations between the universal values and standard systems and cultural diversity or pluralism. But most of the discussions are concentrated on the abstract or conceptual terms, with few touching upon international human fights standards. This is strange, because the disputes will never end and it is impossible to arrive at any conclusions of value if discussions only focus on the different concepts and systems of different countries or civilizations instead of on what has been universally accepted or at least on the international human rights treaties and the customary international human rights laws that are binding to the great number of state parties.

作者：孙世彦 Institute of International Law Chinese Academy of Social Sciences

The optional Protocol to the international covenant on economic, Social and cultural Right was adopted in 2008 and entered into force in 2013? During the five years after its entry into force, 23 States have ratified the optional Protocol, and 23 individual communications have been submitted to the committee on economic,Social and cultural Rights? comparing with the acceptance of individual communication procedures under other core international human rights treaties, the record of ratification of the optional Protocol is not satisfactory? in its examination of individual communications,the committee on economic, Social and cultural Rights has made detailed reasoning, extensively referred to its previous general comments, and in case of violations found, suggested both specific and general remedies? in its practice of examining individual communications, the committee on economic, Social and cultural Rights needs to clarify and define the rights under the covenant and their corresponding obligations, while maintaining its nature and role as a supervisory body, without expanding its competence to an unacceptable extent?

联合国各有关机构都要求各国向其提供有关本国死刑情况的资料,还要求各国公开有关本国死刑情况的资料。基于公众的知情权、公正和有效的刑事司法的要求以及《公民权利和政治权利国际公约》的缔约国报告制度,国家有义务公开死刑资料。公开死刑资料对于公众有关死刑意见的形成和改变具有重要的作用。中国一直没有公开有关判处和执行死刑人数等情况的关键资料,这可能是出于国家形象的考虑。在中国已经提出全面推进依法治国的目标,致力于限制和减少死刑的情况下,公开死刑资料不仅无损国家形象,而且将有利于保障公众的知情权和对死刑使用情况的监督、正确认识死刑的功能和作用、批准《公民权利和政治权利国际公约》以及公众对死刑问题的认识和讨论。

研究重力作用下不同底升角的单圆锥体和双圆锥体垂向入水过程中的砰击压力分布。用OpenFOAM建立基于黏流理论的CFD数值模型,在锥体表面设置监测点,得到不同速度下圆锥体入水时的自由液面形状和锥面上的压力分布,并分析它们与圆锥体底升角和入水速度的关系。研究结果表明:重力和底升角对砰击压力有较为明显的影响;在入水过程中双圆锥体之间相互干扰,锥面上压力增大。

针对目前测试性故障样本量的确定方法过于粗糙和试验样本量过大的问题,提出了合理运用信息熵方法对装备系统各单元的测试性先验信息进行信息融合,得到装备系统级测试性试验数据。在此基础上得到测试性指标的先验分布,并进一步通过Bayes后验风险准则确定故障样本量及试验方案。以某型电动舵机系统各模块的试验数据为例,以故障检测率为测试性指标,经过分析和计算,发现运用所提方法得到的故障样本量相比传统方法明显减少,从而减少了试验成本,同时得到的测试性指标相对误差较小,保证了可信度。

本文揭示了这样一个事实,即就《公民及政治权利国际公约》,同时存在着两个中文本。其中一个在联合国和中国广为使用已经超过30年,但是这一中文本并非该公约的作准中文本。该公约的作准中文本公布在《联合国条约集》上,但很少被有关人权的中文文献所使用。本文对比了这两个文本,并指出在广为使用的中文本中存在着诸多错误。本文还分析了这一局面的法律含义和实践后果,并提出了在法律意义上合理、在实际处理上可行的解决方案。
