New Views over Crime of Extortion Construction and Cognizance

刑法理论界普遍认为，敲诈勒索罪的主要客体是公私财产所有权，次要客体是由本罪特定的犯罪方法决定的人身权利或其它权利。本文拟在批判这种通说见解的基础上，构筑本罪主要客体的价值序位，重新认识本罪的次要客体，并以此为中心，探讨本罪的构成及认定。本文的主文部分共分为三章：第一章分析和重构了本罪的客体，认为本罪主要客体是有本权的占有和未占有的本权，以及两种事实上的占有，即无人享有本权的事实上的占有与只有原权利人享有本权的事实上的占有，并依次分为三个价值序列，前后位阶的客体是递补关系，这也是以威胁方式行使财产权行为的合法根据所在。本罪的次要客体则是为一般犯罪方法所决定的人身自由中的意思决定自由。本章并从辨析...Criminal law theory circles generally consider that primary object of the crime of extortion is public and private poverty ownership. Secondary object is personal rights and other rights which determined by the special criminal means of this crime. The article plan to construct primary object’s value sequence on the base of animadverting the common theory and have a new cognition to the secondary ...学位：法学硕士院系专业：法学院法律系_法学学号：20030802

匈牙利中文学习者否定表达式的习得特点研究

This study takes Hungarian native speakers of Chinese as the research object. It investigates the types of errors they commit in the use of negative expressions and the acquisition characteristics of learners at different levels. An addition of the particle ‘了’ and an omission of ‘到’ are found to be the main types of errors. In terms of acquisition characteristics, it is found that beginners have difficulties distinguishing the subjective and objective directions expressed by ‘不’ and ‘没(有)’. Intermediate and advanced learners’ proficiencies in using negative words fluctuate, as does their accuracy in using negative words, and they tend to use more avoidance strategies本文以匈牙利语母语者为研究对象，采用问卷测试与语料分析相结合的方法，分析了匈牙利学习者使用否定表达式的主要偏误类型及不同水平学习者的习得特点，并提出教学建议。通过研究发现，偏误类型主要有以下几类：误加助词“了”；结果补语“到”的遗漏；述补结构的否定形式使用不当；否定词后接成分形式不当。在习得特点方面：初级水平学习者对否定词“不”和“没（有）”表达的主客观指向区分不明确；中高级水平学习者的主要习得特点为：对否定词使用熟练程度有波动；偏误类型多为否定词位置不当，较少误用否定词；善于使用回避策略；对表示否定存在、所属状况的否定词“没有”的习得障碍较小

Simulation of LDPC Codes over WCDMA Downlink Channels

LDPC码是一类靠近Shannon限的高效信道编码,在AWGN信道下具有非常优越的性能。在讨论了LDPC码的基本原理之后,构建了基于LDPC码的WCDMA下行链路,改进了LDPC码的译码过程。仿真结果表明,在高速传输速率下(384kbit/s),不规则LDPC码具有优于Turbo码的性能,这对于LDPC码应用到复杂无线通信系统中具有重要意义。LDPC codes, which have good performances over AWGN channel, are the efficiently channel coding of near Shannon limits. After describing elements of LDPC codes, LDPC coded WCDMA downlinks were constructed, meanwhile, decoding process was improved. In high rate condition (384kbit/s), simulating results show that performances of irregular-LDPC codes are than that of Turbo codes. It is important value for LDPC coding in complex wireless communication systems.教育部新世纪优秀人才计划(NCET-04-0601);; 福建省科技重点项目(2006H0039)
