述结式的形成和演变过程逐渐成为汉语史研究的重要问题.根据“V成”的句法语义特点,运用语法化理论从历时角度考察述结式“V成”的语法化过程.“V成”可以分为“完成”义和“成为”义,不同的句法语义特点决定了这两种“V成”不同的语法化路径. 相似文献

The first season of Serial, to date the most popular podcast in the medium’s decade-long history, told the story of the conviction of 18-year-old Adnan Syed in 2000 for the murder of his ex-girlfriend, Hae Min Lee. At the center of Serial, producer Sarah Koenig presented Syed’s voice, his take on the prosecution’s evidence, and his own contemporaneous experience. This essay examines the way Serial used Syed’s voice to challenge institutional truth claims from within the textual space of crime journalism. “Criminal biography,” as a genre affordance of true crime, offers a textual means to interrogate modes of truth production and representation. 相似文献

Colorado State University Libraries (CSUL) purchased the digitized United States Congressional Serial Set, 1817–1994 and American State Papers (1789–1838) from the Readex Division of NewsBank, Inc. and, once funds and records were available, the accompanying MARC records. The breadth of information found in the Serial Set is described, along with the difficulties in using the print version (incorporated in the literature review, which includes citations of announcements of the digital collections and reviews of the software). The digital version of the Serial Set has its advantages, but there are additional rewards (much greater discovery opportunities) when items in the digital collection are directly accessible from the library catalog. The purchased MARC records, while overall excellent, had problems that needed to be corrected before they were loaded into CSUL's Innovative Interfaces library catalog. Patron access impact was used as a criterion when determining which of the records would be fixed before loading. High impact problems were identified and solutions derived for: multiple 245 (title) fields; 245 s indicator zero with titles beginning with a, an, or the; dollar sign used in text; fixed field date; languages; subject headings; creating proxy URLs; classification numbers; and author authority control (e.g. corporate entries and presidential entry errors). 相似文献

智能像卡联网门禁系统信息采集研究 总被引:2,自引:0,他引:2
智能像卡联网门禁系统为多门集中管理(如宾馆、办公楼等)提供了一种新型的工作模式,实现这一工作模式的首要任务是进行像卡信息的采集.该文提出一种基于PC机线程像卡测量空间自传送的方法.像卡测量空间由单片机系统控制红外对管阵列而获得,经RS232总线送往联网系统上位机即PC机,PC机采用串口线程工作方式实现实时接收,在主线程中对测量空间进行整定、规范等前置处理工作.此过程的高质量完成,不但为智能像卡联网门禁系统这一新型多门集中管理工作模式的成功实现打下坚实基础,而且为以智能像卡作信息载体的新型模式输入设备的研发提供了可行性依据. 相似文献

现有微控制器的串行口总数一般都很少,如常见的单片机只有一个或二个串口,在利用单片机进行应用系统设计时,往往需要进行串行口扩展。本文总结了目前常用的单片机串行口扩展技术,提出一种利用CPLD扩展单片机串口进行数据发送的方法,具有成本低、设计灵活、节省布线空间等特点。 相似文献

《左传》与《三国志》的连动式比较来看,《三国志》的连动式结构比较复杂,不使用连词占据优势,动词组合更加多样化,语义已经大大丰富。从《三国志》连动式发展可以看出动结式在《三国志》中尚未形成,处于部分连动式向动结式发展的过渡阶段。 相似文献
