铝电解中的阴极过程

对铝电解中的阴极反应、阴极过电压、阴极表面的双电层结构等阴极过程进行了研究,发现在+005～-005V(相对于铝阴极)电位区有一个还原电流峰和一个氧化电流峰,它们是Al3++3e→Al和Al-3e→Al3+·与阳极相比,阴极过电压较小,在001～3A/cm2的Taffel区,约为01V·在阴极表面的双电层中,第一层为Ca2+,Mg2+,Li+和Al3+离子,没有Na+离子,这说明,阴极过电压是因为Mg2+,Ca2+等离子形成的电化学双电层阻力所引起,同时也说明别略耶夫猜想基本是正确的·

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.
