The different amplitudes and latency of ERP components during emotion processing reflect different internal mechanisms. This paper first introduces the ERP study on the interaction between titer and arousal during emotion processing. Then it introduces the influence of different emotional valence and arousal on the reading comprehension process, and expounds the difference of the influence of emotion on reading comprehension among different groups. Then the interaction between emotionality and lexicology in the process of reading comprehension is briefly explained. Finally, the above aspects of the research are summarized, and the future research direction is proposed.展开更多
从鼎湖鳞伞菌发酵液中提取、纯化得到胞外多糖(Pholiota dinghuensis Bi exopolysaccharides,PDEPS)-1,采用体外模拟唾液、胃液、胃肠液模型与分析还原糖含量、分子质量变化及游离单糖含量,探讨了PDEPS-1在体外模拟消化液中的变化。结...从鼎湖鳞伞菌发酵液中提取、纯化得到胞外多糖(Pholiota dinghuensis Bi exopolysaccharides,PDEPS)-1,采用体外模拟唾液、胃液、胃肠液模型与分析还原糖含量、分子质量变化及游离单糖含量,探讨了PDEPS-1在体外模拟消化液中的变化。结果表明:PDEPS-1的中性糖含量为97.97%,含少量蛋白、糖醛酸及硫酸基,不含还原糖,分子质量为17.95 k D,由甘露糖及半乳糖组成,物质的量比为53.32∶6.43。PDEPS-1在唾液中不被消化,分子质量不变,没有还原糖及单糖的生成;在模拟胃液及胃肠液中有还原糖产生,但没有检测到单糖。因此,PDEPS-1在体外模拟的3种消化液中具有一定的耐消化性。展开更多
