作者 何强 《北京社会科学》 CSSCI 北大核心 2018年第2期60-68,共9页
天降赤雪是一种极为罕见的自然现象,从南朝沈约开始,人们都将此视为赤祥,并进行了相应政治事应模式的建构。而宋朝孙甫却将其视作赤眚。孙甫从赤祥到赤眚的书写,反映了从南朝到北宋人们在灾异政治观念和实践上的某些变化。分析孙甫《上... 天降赤雪是一种极为罕见的自然现象,从南朝沈约开始,人们都将此视为赤祥,并进行了相应政治事应模式的建构。而宋朝孙甫却将其视作赤眚。孙甫从赤祥到赤眚的书写,反映了从南朝到北宋人们在灾异政治观念和实践上的某些变化。分析孙甫《上仁宗论赤雪地震之异》疏,对认识宋朝灾异与政治的关系、灾异政治的实践效果及其内在局限,当有所裨益。 展开更多

Based on this correlation, they are named characteristic organic compounds. The compounds found are sequalene (SQU), cedrol (CED), 2, 5-cyclohexadiene-1, 4-dione, 2, 6-bis(1, 1-dimthylethyl ) (PBQ), phenol, 2, 6-bis (1, 1-dimethylethy-4-methyl) (BHT), 3-t-butyl-4- hydroxyanisole ( BHA ), 1, 2-benzenedicarboxylie acid, bis-( 2-methyl propyl ) ester (DIBP), dibutyl phthalate (DNBP), respectively. Monitoring the variations of concentration of these characteristic organic compounds in seawater may provide scientific basis for studying and forecasting red tides. 展开更多
