斯巴克 Cayin A-300B综合功放

即使是那些短视的批评家们现在也不得不承认,自十年前起重现美国国内音频市场的单端真空管功放,不仅仅代表了一股逝去的潮流.尽管这类同任何一款普通扬声器搭配都有问题的功放都决不会成为司空见惯的产品,但同为现实的是,SET(单端真空管功放)的魅力已让它在市场中永远占据着一席之地.总会有制造商想要生产SET,正如总有人想要扮演莎士比亚或蒸馏苦艾酒.     

PM10 speciation and determination of air quality target levels. A case study in a highly industrialized area of Spain

The paper shows how PM speciation studies allow the evaluation of the strategies to be followed to diminish PM pollution in highly industrialized areas with a large number of potential pollution sources. Evolution of levels and speciation of PM10 in the ceramic producing area of Castelló (East Spain) was studied from April 2002 until December 2005. PM10 levels were measured at one rural (Borriana-rural), two suburban (Almassora and Onda) and three urban (Borriana-urban, L'Alcora and Vila-real) sites, all influenced by the ceramics industry. Average PM10 levels varied between 27 and 36 microg/m3 for the study period. Evaluation of 1996-2005 PM data from Onda shows a clear decrease of PM levels since the beginning of 2002. Summer peak levels and winter minima occurred at both rural and suburban sites, whereas urban sites had no clear seasonal trend, with high PM10 episodes being due variously to local, regional, and African dust intrusion events. PM10 chemical analysis at four of the sites showed the dominant constituent to be mineral matter, exceeding by 5-12 microg/m3 the usual ranges of annual mineral loadings in PM10 at comparable Spanish urban or regional background sites with no industrial influence. Given current PM10 loadings, we recommend a lowering target of 3-5 microg/m3 of the annual mean at the urban sites, which should be achievable given available emission abatement techniques.     

论产品设计的形式与限定

通过对产品设计形式重要性的阐述，说明了产品的形式是产品诸多功能的外在表现，是设计师工作中的重要内容；而设计师通过对产品设计形式的再认识便可在限定中求新意，使产品设计的形式与功能达到谐调统一．     

Detection techniques for MIMO spatial multiplexing systems

We discuss and compare the most important detection techniques for MIMO spatial multiplexing wireless systems, focusing on their performance and computational complexity. Our analysis shows that the limited performance of conventional suboptimal detection techniques is primarily caused by their inability to cope with poorly conditioned channels. The recently proposed sphere projection algorithm is better suited to these channels and can achieve near-optimal performance.
