In this work, some theoretical works on CO adsorp‐tion, O2 adsorption, atomic oxygen adsorption, formation of surface gold oxide films, reaction mechanisms of CO oxidation involving O2 reaction with CO and O2 dissociation before reacting with CO on gold surfaces and Au/metal oxide were summarized, and the influences of coordination number, charge transfer and relativity of gold on CO oxidation reaction were briefly reviewed. It was found that CO reaction mechanism depended on the systems with or without oxide and the strong relativistic effects might play an important role in CO oxidation reaction on gold catalysts. In particular, the relativistic effects are related to the unique behaviors of CO adsorption, O adsorption, O2 activation on gold surfaces, effects of coordination number and the wide gap between the chem‐ical inertness of bulk gold and high catalytic activity of nano gold. The present work helps us to understand the CO oxidation reaction mechanism on gold catalysts and the influence of relativistic effects on gold catalysis.展开更多

Personality factors could predict relationship satisfaction through the influence of individuals＇ relationship schemas （Fiske and Taylor 1991） and perceptions of their partners （Simpson and Rholes 1998）. Given the potential importance of attachment styles to relationship mechanisms and the well-established relationship between attachment and interpersonal behavior （Bartholomew and Horowitz 1992; Hazan and Shaver 1987）, interpersonal traits may influence relationship satisfaction directly. According to Leary＇s （1957） interpersonal reflex theory, any interpersonal act elicits responses from the other person that verify, validate, or otherwise reinforce the actor＇s own self-image and self-presentation, and thus increase the probability that the actor will emit similar interpersonal acts in future interactions. The Impact Message Inventory （IMI） attempts to measure individuals＇ perceptions of how others impact them by evoking interpersonal acts such as dominance and affiliation. This study examined the influence of perceived partner-evoked behavior and individuals＇ own interpersonal styles on relationship satisfaction. This study used IMI measures of evoked Dominance and Affiliation as well as revised Liking and Loving measures to predict relationship satisfaction using three different satisfaction outcome measures. The final analyses included 291 participants （134 men and 157 women） who completed a scantron survey. Partner impact, or the interpersonal behaviors, evoked from the individual during interaction, predicted relationship satisfaction well. Evoked affiliation was the most consistently strong predictor of satisfaction across all three outcome measures. Liking （distinct here from affiliation） is a stronger predictor of relationship satisfaction than is loving （distinct here from passion）, and it is significant across all three outcome measures. The liking measure appears to reflect a relatively high level of reward in the relationship and intrinsic enjoyment of the partner＇s company without the comparative cost of loving. Future research should examine interactions between couples, moving beyond intrapsychic self-reports of perceived experiences and feelings, although these are important in their own right.展开更多
