并行工程产品开发过程的建模方法学

在并行工程中，为了实现产品开发过程的集成、并行和最优化，首先要建立能够充分反映产品开发过程各方面信息的产品开发过程模型。通过对模型的仿真分析和优化，指导产品开发过程的实施。本文首先提出了并行工程产品开发过程模型是集成多视图模型，随后提出了采用集成多视图建模理论的并行工程产品开发过程建模、分析和管理的方法学框架     

铅锡合金沉积物的显微组织

将离子浓度比为5∶5的铅锡电沉积分形生长沉积物制备成金相样品，用金相显微镜观察了它们的显微组织。结果表明，在此情况下，铅锡电沉积生成物由两相组成，即铅锡共晶相和铅基固溶相，两相呈交替层状分布。

知识经济的可持续发展刍议

知识经济被视为实现可持续发展的必由之路，但它本身也有个可持续发展的问题。知识经济本质上是人的经济，它淡化了经济发展对天然资源的依赖关系，强化了对人自己创造的知识资源的依赖性，使得科技和教育的发展成为实现其可持续发展的关键；同时，处理和运用知识的手段和能力是知识转化为资源的重要环节，高科技产业的发展也因之成为其必要的条件；知识经济又是商品化经济，知识产权的保护等措施是保证知识生产和再生产顺利进行的环境支持。

Static extracting method of software intended behavior based on API functions invoking

The method of extracting and describing the intended behavior of software precisely has become one of the key points in the fields of software behavior＇s dynamic and trusted authentication. In this paper, the author proposes a specified measure of extracting SIBDS （software intended behaviors describing sets） statically from the binary executable using the software＇s API functions invoking, and also introduces the definition of the structure used to store the SIBDS in detail. Experimental results demonstrate that the extracting method and the storage structure definition offers three strong properties： （i） it can describe the software＇s intended behavior accurately; （ii） it demands a small storage expense; （iii） it provides strong capability to defend against mimicry attack.     

Effects of self evaluation on late ERP components

High-density event-related potentials (ERPs) were measured when participants were required to evaluate oneself, significant others (father and mother) and the most familiar public figures (Lei Feng and Jiang Qing) based on trait adjectives. There were three referential conditions and a non-referential control condition including self-evaluation (SE), significant other-evaluation (SOE), general other-evaluation (GOE), and semantic positivity-evaluation (SPE). The behavioral data showed that RTs to GOE condition were longer than the other three conditions. Scalp ERP analysis revealed that (1) SPE condition elicited a more negative N2 than SE condition, which was associated with inhibition of responses; (2) SE condition elicited a more positive P300 than SPE condition, which was an index of attention to self-relevant stimuli; (3) there was no difference on the amplitude and latency of P300 between SE and SOE conditions, which reflected that the concept of “self” included intimate others (e.g., father and mother) in Chinese culture.
