绿色、环保、无铅已经成为电子制造企业频频提起的字眼。而随着欧盟《关于废弃电子电气设备指令》(WEEE指令)和《关于在电子电气设备中禁止使用某些有害物质指令》(ROHS指令)的逐步实施,以及我国《电子信息产品污染防治管理办法》的出台,电子制造企业已经没有退路,必须面对无铅化电子制造所带来的挑战。  相似文献

按照欧盟的规划,《关于在电子电气设备中限制使用某些有害物质指令》(即RoHS指令)将于2006年7月1日正式实施,这样进入欧盟市场的所有电子电器产品必须符合RoHS指令的要求。包括中国企业在内的所有欲出口欧盟市场的电子电器企业都必须获得经过专业检测机构颁发的认证许可证书,该证书是进入欧盟市场的通行证。当前,法国、英国、德国、美国等国家的专业检测公司开始在中国兜售检测业务,为应对欧盟的RoHS指令,中国针对电子电器产品检测的市场正在兴起。  相似文献

中国的入世和中国电信业的重组对不同的运营商会产生不同的影响。总的来讲,网间结算和网间互联互通成本将增加,在网络技术演进等方面必然出现南北差异,电信全程全网的特性受到限制,网络效率将会降低,南北部分重复建设的出现已不可避免。中国电信规模减小,普遍服务体系受到冲击;网通优势增加,但需首先做好内部融合;其他运营商互联互通工作量增加,但扩大了选择范围。  相似文献

A model of the dynamics of organizational romance is important because organizations are a natural environment for the emergence of romantic relationships. Their emergence is feared and these fears influence decisions about the acceptability of women in organizations. The frequency of such relationships is likely to increase with more women in the work force. Little is known about the phenomenon in general. Qualitative data from interviews with third parties and numerical data from a questionnaire are used to delineate the types and varieties of behavior associated with the formation, impact, and management of organizational romance. Factors in the formation of romantic relationships are proximity, motives, and characteristics of the work group or setting. Visibility of the relationship, behavior changes by participants, the reactions of members, and overall changes in the system are delineated as elements in understanding the impact of organizational romance. In considering the management of romantic relationships, three types of behavior are identified: no action, punitive actions, and positive actions. The impact of organizational romance is discussed in terms of Weberian assumptions and beliefs, exchange theory, personal costs, and social equity.  相似文献

Negative-bias-temperature instability (NBTI) has become the primary limiting factor of circuit life time. In this paper, we develop a hierarchical framework for analyzing the impact of NBTI on the performance of logic circuits under various operation conditions, such as the supply voltage, temperature, and node switching activity. Given a circuit topology and input switching activity, we propose an efficient method to predict the degradation of circuit speed over a long period of time. The effectiveness of our method is comprehensively demonstrated with the International Symposium on Circuits and Systems (ISCAS) benchmarks and a 65-nm industrial design. Furthermore, we extract the following key design insights for reliable circuit design under NBTI effect, including: 1) During dynamic operation, NBTI-induced degradation is relatively insensitive to supply voltage, but strongly dependent on temperature; 2) There is an optimum supply voltage that leads to the minimum of circuit performance degradation; circuit degradation rate actually goes up if supply voltage is lower than the optimum value; 3) Circuit performance degradation due to NBTI is highly sensitive to input vectors. The difference in delay degradation is up to 5$times $ for various static and dynamic operations. Finally, we examine the interaction between NBTI effect, and process and design uncertainty in realistic conditions.   相似文献

Previous research has suggested that exposure to political advertising is generally informative and may even reduce information gaps between the most and least aware in society, but does not produce large shifts in candidate preference. Drawing on extant models of opinion change, we predicted that the informational benefits of political ads would vary by level of awareness, such that the most aware would experience the largest gains, especially when they are asked to make inferences about issues not explicitly discussed in the ad. Further, we predicted that the most aware would use information in advertisements as a substitute for other kinds of information seeking, while the least aware would be relatively unmotivated to seek out new information, regardless of exposure. Finally, the least aware would be more susceptible to persuasion via ads than the most aware would be. Experimental evidence confirmed these predictions.  相似文献
