《聊斋志异》与聊斋俚曲——兼论《仇大娘》与《翻魇殃》

蒲松龄在晚年创作了大量俚曲,其中有七部的题材与《聊斋志异》中的小说相同。他写作与小说同一题材俚曲的目的是用一种寓教于乐的文艺形式对村庸市媪进行教化,表现的主题都是普通百姓日常生活中所关心的问题,充满了对整个社会和底层人民的关注。作家还特意选择了俚俗的语言进行创作,为后人改编《聊斋志异》奠定了家庭化、世俗化的基调。

“科学社会主义基本原则”研究述评

中国特色社会主义是经过两次裂变才从资本主义的社会形态中产生出来的,第一次裂变产生的是资本主义的对立物——科学社会主义,而第二次裂变产生的是社会主义的继承物——中国特色社会主义。中国特色社会主义与科学社会主义拥有相同的血脉,这条血脉就是科学社会主义基本原则。科学社会主义基本原则既然是马克思主义基础理论里面本质的、规律的东西,那学界就有可能对此达成共识。

稻草强化生物膜浮床脱除工业尾水中氮素及COD的效果

工业污水处理厂排放的尾水中总氮含量偏高,容易引起地表水体的富营养化。为了提高尾水中总氮的去除效率,通过模拟稳定塘静态和动态试验,对比了不同稻草添加量(0,0.18,0.54 g/L)强化生物膜浮床脱除工业尾水中总氮(TN)的效果。静态试验结果表明:随着稻草量的增加,TN的去除率显著提高;10 d后,添加0(CK)、0.18 g/L(T1)和0.54 g/L(T2)稻草的尾水中,TN去除率分别为18%,40%,93%。动态试验结果显示,水力停留时间(HRT)为 4 d时,CK、T1和T2的平均TN去除率分别为10%,22%,49%,且3种情况下的进出水COD浓度无显著差异。这主要是由于稻草通过缓慢释放碳源为生物膜中异养反硝化细菌提供可利用的有机物。研究成果可为工业尾水深度处理脱氮技术提供参考。     

Multi-species particle swarms optimization based on orthogonal learning and its application for optimal design of a butterfly-shaped patch antenna

A new multi-species particle swarm optimization with a two-level hierarchical topology and the orthogonal learning strategy(OMSPSO) is proposed, which enhances the global search ability of particles and increases their convergence rates. The numerical results on 10 benchmark functions demonstrated the effectiveness of our proposed algorithm. Then, the proposed algorithm is presented to design a butterfly-shaped microstrip patch antenna. Combined with the HFSS solver, a butterfly-shaped patch antenna with a bandwidth of about 40.1% is designed by using the proposed OMSPSO. The return loss of the butterfly-shaped antenna is greater than 10 d B between 4.15 and 6.36 GHz. The antenna can serve simultaneously for the high-speed wireless computer networks(5.15–5.35 GHz) and the RFID systems(5.8 GHz).     

氯化锂对纤维素/离子液体浓溶液纺丝的影响

以离子液体1-烯丙基-3-甲基咪唑氯盐（[AMIM]Cl）为溶剂、氯化锂（LiCl）为添加剂,通过测定纤维素溶液的流变性能来考察LiCl对纤维素/[AMIM]Cl溶液纺丝性能的影响,发现纤维素/[AMIM]Cl/LiCl呈现切力变稀行为,当LiCl添加量为[AMIM]Cl质量的3%时,切力变稀行为最明显.使用双螺杆挤出机通过干湿法纺丝制备出了高浓度的纤维素纤维,通过XRD、偏光显微镜、SEM及单纤强力仪等表征了纤维的结构与性能,结果表明随着LiCl含量的增加,所得纤维的结晶度和双折射率增加,结构致密,纤维强度增加,当LiCl含量达3%时,纤维强度可达3.13 cN/dtex.     

中国英语学习者汉语恭维应答语语用“外借迁移”现象研究

通过情景选择及补全对话测试考察了中国英语学习者（英专组和非英专组）汉语恭维语应答的情况。与一组从未接受过英语教育的受试（零英语组）进行对比,结果表明,英专组应答时遵守赞同准则而产生了语用“外借迁移”现象,而非英专业组与零英语组应答方式均遵守谦虚准则。优选论分析表明,产生“外借迁移”现象是由于英专组在应答时将赞同准则列为高级别制约条件;而非英专组在作答时仍以谦虚准则为高级别制约条件。     

Fabrication process of smooth functionally graded materials through a real-time inline control of the component ratio

Functionally graded materials (FGMs) play an essential role in tissue engineering because of their satisfactory histocompatibility and excellent mechanical performance. While traditional manufacturing methods allow production of simple FGMs, precise control of composition and customized property at transition between the dissimilar materials is still a challenge. Here, an extrusion-based functionally graded additive manufacturing (FGAM) platform was developed to generate smooth graded parts by thrusting out monolithic cylindrical filaments with high viscosity. Furthermore, the rheological properties, hydrodynamic behavior, and mixed homogeneity of the non-Newtonian fluids were studied. Therefore, the appropriate solid contents, alternative energy-efficient mixers, and optimized printing parameters were proved to be beneficial for an outstanding deposition effect of the suspension. Ultimately, an object with smooth gradient was successfully manufactured. The validity of this strategy was verified via optical microscopy combined with an image processing method to gauge homogeneity and a scanning electron microscope to investigate graded composition and microstructure.
