南四湖港口污染物扩散区COD降解系数的研究 总被引:1,自引:0,他引:1
本文对南四湖港口污染物扩散区内的COD降解规律进行了室内模拟试验研究,采用最小二乘法估计出了COD可降解部分的降解系数和不可降解部分的百分比,并通过方差分析验证了模型的可靠性。COD降解系数和不可降解百分比的获取,可以为预测各港口对南四湖水质变化趋势的影响,为制定相应的水污染防治规划和措施,提供了重要的基础数据。 相似文献

Despite the importance of apology in reconciling interpersonal transgressions, little research has focused on the people engaging in the behavior. Why do transgressors apologize in the workplace, and do apology motives shape transgressor perceptions of reconciliation? We conducted three field studies using qualitative and quantitative methodologies to examine these questions. In Studies 1 and 2 (total N = 781), we identified four distinct apology motives—self‐blame, relational value, personal expedience, and fear of sanctions—and developed self‐report scales to measure the motives. In Study 3 (N = 420), we examined relations between apology motives and transgressor perceptions of victim forgiveness and relationship reconciliation through the lens of motivated cognition. We found that apologizing due to self‐blame, relational value, and personal expedience increases perceptions of victim forgiveness, whereas apologizing due to fear of sanctions decreases perceived forgiveness. Moreover, mediation analyses revealed that motives indirectly influence transgressor perceptions of relationship reconciliation through perceived forgiveness. Taken together, our research presents a novel multidimensional perspective on apology‐giving in the workplace, suggesting that why transgressors apologize can affect their perceptions of reconciliation. Overall, our research highlights the need to incorporate transgressor cognitive and motivational processes into reconciliation research. 相似文献

Impact of dicyandiamide on emissions of nitrous oxide, nitric oxide and ammonia from agricultural field in the North China Plain 总被引:1,自引:0,他引:1
Nitrous oxide(N_2O), nitric oxide(NO) and ammonia(NH_3) emissions from an agricultural field in the North China Plain were compared for three treatments during a whole maize growing period from 26 June to 11 October, 2012. Compared with the control treatment(without fertilization, designated as CK), remarkable pulse emissions of N_2O, NO and NH_3 were observed from the normal fertilization treatment(designated as NP) just after fertilization, whereas only N_2O and NH_3 pulse emissions were evident from the nitrification inhibitor treatment(designated as ND). The reduction proportions of N_2O and NO emissions from the ND treatment compared to those from the NP treatment during the whole maize growing period were 31% and 100%, respectively. A measurable increase of NH_3 emission from the ND treatment was found with a cumulative NH_3 emission of 3.8 ± 1.2 kg N/ha,which was 1.4 times greater than that from the NP treatment(2.7 ± 0.7 kg N/ha). 相似文献
