Accurate simulation of lightning-induced overvoltage for overhead distribution lines is helpful to prevent lightning trip *** electromagnetic return-stroke model was used to represent lightning and then a 3D finite-difference time-domain(FDTD)method was adopted to simulate the lightning-induced overvoltage on a distribution line without a field-line coupling *** lightning-induced overvoltage behave for different ground conductivity and varying distance between the distribution line and the lightning channel was *** results showed that the overvoltage waveforms at the centre point of the line corresponding to lightning strikes on the lossy ground and an ideal ground(σ=∞)were similar;however,the peak amplitudes of the waveform were affected by soil conductivity at a close *** relationship between magnitude of the overvoltage and distance can be described by a second-order exponential decay ***,the overvoltage calculated using the proposed model was compared with those obtained based on Agrawal's model and measurements made using the newly developed intelligent insulator on *** these comparisons,it could be concluded that the FDTD method with the electromagnetic return-stroke model produces reasonably accurate results of the attenuated oscillation waveform,which can better reproduce the overvoltage on operational distribution lines.

《神弦歌》十一曲包含十八首诗歌,是《乐府诗集》中一组特殊的祭祀歌曲,其结构经过精心设计,各曲之间前后呼应、环环相扣,营造出特定的神性空间,并通过歌舞表演完成一场较大规模的祭祀仪式。作为一组用于祭祀的诗歌文本,《神弦歌》还具有戏剧脚本的提示功能,可以据此绘制出一张清晰的神灵空间分布图;其祭祀仪式融入了散乐百戏的表演体制,具有一定的情节内容,呈现出一种初级的戏剧形态,乃是六朝时期江南水乡祭祀歌舞活动的一份生动记录,对研究中国早期戏剧的发展情况,具有不容忽视的参考价值。

作为文体的“乐府”,其由机构之名演变而来的关键环节值得探讨。西晋挚虞的《文章流别论》分离了诗与歌,改变了诗、歌一体的传统观点,并把“乐府”与“汉郊庙歌”“俳谐倡乐”相提并论,体现了“乐府”的含义乃从官署之名到音乐之名,再到文体之名,并非从官署之名直接到文体之名。刘勰在《文心雕龙》中则特别接受刘向《说苑·修文》的“诗与歌别”之论,于《明诗》之后再列《乐府》之篇,一以论诗,一以论歌,在中国乐府理论史上具有里程碑意义。他认为“乐府”指可以入乐(但未必入乐)的歌辞,并把上古歌辞和郊庙歌辞都归入乐府,这在当时显得独树一帜,却在后世成为乐府的主流定义,对一系列乐府著作和乐府总集产生了深刻影响。

汉代铎舞歌辞《圣人制礼乐篇》释读补论

汉代铎舞歌辞《圣人制礼乐篇》的释读，前辈学者的观点不尽一致。文章首先着眼于其自身的“舞蹈歌辞”属性，分析铎舞表演时的舞姿舞容、舞者所持乐器特征，逆推歌辞如何与伴奏音乐、舞蹈动作相互谐和，而后从汉字音韵与舞蹈动作节奏、伴舞音乐节律的互通互鉴的角度讨论《圣人制礼乐篇》的释读，对既有研究做出补充。歌辞中出现的“邪”“乌”“吾”等“声辞”都出现在某一小句的尾部，恰好对应铎舞演出时“踏地低昂，手足相应”的动作。此阶段配乐节奏舒缓，伴乐而唱的歌辞则会拖长，释读时应将其与二合“声辞”前字所表示的相应“声辞”的辅音部分结合起来考虑。从铎舞表演时舞者所持乐器特征来看，振铎发出的声音刚健而清脆，而舞者振铎击节与刚猛浑雄的舞蹈动作共同作用更加深了节奏的脆断感，此时往往与汉语入声字产生关联，入声字后的“邪”“吾”“乌”很可能为单一“声辞”,需要特别重视。
