Newly developed sintering aid Na5.6Cu1.2Sb10O29 (NCS) and lead-bismuth-free piezoceramics (Na0.5K0.44Li0.06) Nb0.95Sb0.05O3 (NKLNS) were prepared by the conventional solid state reaction. The effects of sintering aid NCS on the electrical properties of NKLNS were investigated. It was found that the addition of a proper amount of sintering aid NCS to NKLNS is effective not only on improving the density and the piezoelectric activity, but also on reducing the dielectric loss of NKLNS. The NKLNS doped with 0.4 mol% NCS has a piezoelectric constant d33 as high as 261pC/N and an electromechanical coupling factor k33 above 60%. These results show that NCS-doped NKLNS is a promising and practicable candidate for lead-bismuth-free piezoceramics.

"十七年"的主流意识形态力图通过文艺为新政权、新社会和广大人民构建出一个想象的历史共同场域,以便简洁、有力、高效地构建起新中国执政党统治的史实合法性和逻辑真理性的科学本质。"十七年"战争小说情爱叙事的几大普泛性叙事策略,就是两性私爱被组织进民族/阶级解放的宏大政治话语中不同的具体方式。主要体现为叙事方法上对人物情爱故事的典型化的裁剪和组合,和叙事伦理上对作为战争深层动力的个体爱欲的政治化置换。这种以集体战争语法与个体情爱语义的叙事互动,同时也是个体私己情爱欲望被意识形态所规训的话语痕迹。

中国文学中的英雄叙事具有显著的民族特色,大陆建国初期的红色经典和港台的武侠小说都深受中国传统文化中“和而不同”的民族思维特质的影响。本文试图论述这两种类型英雄叙事中人物塑造方面的相通之处及其文化同质同构性,即对人物性格的“锥形化”处理方式,以及这种处理方式所带来的英雄人物性格配置结构格局中的“点阵模式”。
