由《日光流年》看阎连科小说的叙事美学

作为阎连科的一部重要作品,《日光流年》具有一种标本的价值。从本质上说,阎连科知识分子与农民身份的二重性决定了其乡村小说的基本情感色调是多色杂糅的,它又影响到这些小说的叙事方式和审美特征,如神话模式、苦难意识、“方言”的关注以及狂欢话语等,这些特征都在《日光流年》中有所体现,它们共同构建了阎连科小说的叙事美学。     

Characteristics of the crustal structure and hypocentral tectonics in the epicentral area of Nan’ao earthquake (M7.5), the northeastern South China Sea

1918 Nan’ao earthquake (M7.5) occurred in the northeast coastal areas of Guangdong Province. With the seismogeological survey of the epicentral area and history materials analyses, the earthquake epicenter was estimated to locate in the intersection part of the Binhai fault zone (Littoral) and Huanggangshui fault, which strikes NEE and NW, respectively. The activities of the NEE-striking thrust fault and NW-striking extensional fault that were attributed to 1918 Nan’ao earthquake occurred in the Dongshan Island of the epicentral area; they reflected the focal stress field with compression in NW-SE direction and extension in NE-SW direction. The isoseismal contour of seismic intensity X shows a shape of ‘X’ composed of two mutually overlapping ellipses with two axes striking NEE and NW, respectively, and such shape implies that the occurrence of this earthquake is controlled by a pair of conjugate seismotectonic faults constituted by the NEE-striking Binhai fault zone and the NW-striking Huanggangshui fault. The Binhai fault zone is a dominant seismogenic structure, and the NW-striking Huanggangshui fault is the subdominant one. The onshoreoffshore deep seismic profile that crossed the epicentral area and was perpendicular to the strike of the Binhai fault zone was obtained. According to the analyses of the seismic data, the Binhai fault zone is defined as a low velocity zone with SE dip-slip in thecrustal structure section. The Binhai fault zone is a boundary fault between the South China subplate and South China Sea subplate. The crust structure on the northwest side of Binhai fault zone is a normal continental crust with a thickness of 30 km, and the one on the southeast side of the fault zone is a thinning continental crust with a thickness of 25―28 km. The Binhai fault zone is an important seismogenic fault and also is an earthquake-controlling fault. The intersection part between the Binhai fault zone and the low velocity zone of upper crust is advantageous to stress concentration and strain energy accumulation, and presents the deep dynamic conditions for the earthquake’s pregnancy and occurrence.     

天津市滨海新区典型制造业与生产性服务业的产业关联与空间关系研究

天津滨海新区以发展现代制造业为主,形成了电子通讯、石油化工、海洋化工、机械制造、生物医药等七大主导产业,成为北方区域经济发展的增长极.但滨海新区制造业所占比重较大,服务业的发展滞后,生产性服务业对制造业的支撑作用不明显.本文根据天津滨海新区统计年鉴中分行业全部国有及规模以上工业总产值将其中的通信设备、计算机及其它电子设备制造业作为研究对象,确定了配套的生产性服务业,并分析了滨海新区典型制造业与其配套的生产性服务业在空间分布上的集聚特征与空间分布的一致性,结论是:滨海新区2007年生产性服务业的各行业中间需求率比2002年均有所下降;通信设备、计算机及其他电子设备制造业对生产性服务业的中间需求仍以传统服务业为主,对中间投入服务的消耗层次偏低;滨海新区内制造业和配套的生产性服务业在空间分布上的集聚性不显著,二者的空间分布差异性明显,就业的空间分布一致性较差.     

共振峰编辑法区别鼻化元音中口、鼻音共振峰的实证探究*

为解决司法话者识别中利用鼻化元音构建元音声学空间图时如何准确判别鼻化元音的口、鼻音共振峰的问题。本文通过计算机语音工作站对语音样本的共振峰进行编辑操作，利用生成的语音样本构建不同的对照组分别进行听辨。结果表明，口音、鼻音共振峰分别被衰减后的语音变化特点呈现一定规律，使用此方法可以准确区分鼻化元音的口、鼻共振峰的阶次。本文建立的“共振峰编辑”与“听觉感知”相结合的判别方法，可以为司法话者识别及语音感知、识别等相关领域通过构建元音声学空间图进行声学特征研究的模型提供口音、鼻音共振峰的判别依据。
