古代儒家“诗教”思想之大众化传播

作者：李梅梅鞍山师范学院文学院辽宁鞍山114007

先秦孔子以"诗"为教,言修身当先学诗,强调诗的政治教化作用,即为"诗教"。后世推尊儒学,奉《诗》为经,"诗教"思想遂传承久远。探其广传之根源,其一,"赋诗言志"[1]对春秋时期"诗教"思想的传播起到了极好的推介作用;其二,"独尊儒术"是"诗教... 详细信息

先秦孔子以"诗"为教,言修身当先学诗,强调诗的政治教化作用,即为"诗教"。后世推尊儒学,奉《诗》为经,"诗教"思想遂传承久远。探其广传之根源,其一,"赋诗言志"[1]对春秋时期"诗教"思想的传播起到了极好的推介作用;其二,"独尊儒术"是"诗教"思想极盛于汉的重要原因;其三,封建科举取士制度是隋唐及此后"诗教"思想在士子阶层广为传承的根本原因;其四,宋元明清时期话,本小说、杂曲百戏等民众喜闻乐见的通俗文艺样式,也使"诗教"思想得以在市井细民之间广泛传承。及至近代,虽因读经之衰落而致"诗教"思想沉寂良久,但今人若能在继承古之"诗教"传统基础上,假之现代科技之条件,丰富创新"诗教"之传播方式,必将有利于"诗教"思想之复兴,有助于"诗教"兴国之大业。

Side reactions and dendrite growth triggered by the unstable interface and inhomogeneous deposition have become the biggest obstacle to the commercialization for lithium metal *** this study,a highly-chlorinated organic-inorganic hybrid interfacial protective layer is developed by rationally tuning the interfacial passivation and robustness to achieve the convenient and efficient li metal *** polyvinyl chloride(PVC)can effectively resist water and oxygen,which is confirmed by density functional *** organic-dominant solid electrolyte interphases(SEI)with lithium chloride are investigated by the X-ray photoelectron spectroscopy(XPS)with little mineralization of oxide,such as li_(2)O and li_(2)CO_(3).With such artificial SEI,a uniform and dense lithium deposition morphology are formed and an ultra-long stable cycle of over 500 h are achieved even at an ultra-high current density of 10 m A/cm^(2).Moreover,the simple and convenient protected anode also exhibits excellent battery stability when paired with the liNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)(NCM811)and liFePO_(4)(LFP)cathode,showing great potential for the commercial application of lithium metal batteries.

阻塞性睡眠呼吸暂停低通气综合征(OSAHS)主要临床表现为睡眠过程中反复性出现上气道阻塞、塌陷,致使呼吸中断或/和出现不同程度的低通气,引起睡眠结构紊乱、高碳酸血症,导致患者出现打鼾、白天嗜睡、睡眠结构紊乱等症状,损害患者的神经系统、代谢系统、消化系统、泌尿生殖系统、内分泌系统,导致患者的免疫功能、性功能、代谢功能出现异常。临床实践可知,OSAHS是导致人们发生高血压、心脑血管疾病(脑卒中、冠心病等)、肺源性心脏病的一项独立危险因素,OSAHS将会影响人体胸腔内压力的波动情况,导致机体的血压增高,引起动脉粥样硬化(AS),严重损害患者的机体,而这些症状的发生都会引起动脉扩张性血管瘤,或者加速动脉扩张性血管瘤的进展。
