The purpose of this study is to prove the relationship between regret emotions and a sense of responsibility and control. The results show that the individual＇s sense of responsibility and regret that there is a positive correlation and there is a negative correlation between the control and regret, which is not match the previous part of the study so as to be further explored. At the same time, we found that the regret tendencies in the personality can be explained as some of the regret experiencing in the specific situation. When people realize or imagine that ＂if the choice is not the same as before that things are getting better now＂, they will feel regret.展开更多

The Eight structured packings tested are sheet metal ones with corrugations of different geometry parameters. Effective mass transfer area and overall gas phase mass transfer coefficient have been measured in an absorption column of 200 mm diameter under the conditions of gas F-factor in 0.38–1.52 Pa0.5and aqueous Na OH solution concentration of 0.10–0.15 kmol·m-3. The effects of gas/liquid phase flow rates and packing geometry parameters are also investigated. The results show that the effective mass transfer area changes not only with packing geometry parameters and liquid load, but also with gas F-factor. A new effective mass transfer area correlation on the gas F-factor and the liquid load was proposed, which is found to fit experiment data very well.展开更多
