Theoretical study of intramolecular interactions

分子张力或者分子内排斥对于解释分子构象、分子的弯曲振动、分子的化学反应等很多实验现象有着非常重要作用。但是，相比对分子间相互作用的研究，目前对于分子内排斥作用的研究还较少。分子内的轨道排斥作用如σ-σ轨道排斥和孤对-孤对排斥为大家所普遍认知，但其他的轨道排斥，如π-π轨道排斥、孤对-π排斥并未被大家所意识到。价键方法作为重要的多组态量子化学计算方法，凭借其清晰的物理图像以及与经典化学概念相吻合的特征，在揭示化学键的本质方面有着无可比拟的优越性。在本论文的研究中，我们主要应用价键方法最简单的变体，块定域化波函数(BLW)方法，对一些涉及分子内排斥和共振的化学问题进行详细的研究。另外，近几年Hib...“ Intramolecular strain” or “ Intramolecular repulsion” can provide help in our understanding of molecular structures and properties. Most chemists have intuitive feelings about the concept of them: what it is or how certain reactions will behave under its influence. There have been numerous approaches in the probe and decomposition of intermolecular interactions. But in general these approa...学位：理学博士院系专业：化学化工学院_物理化学学号：2052013015387

Analysis and Design of Warehouse Management System for Community Supermarkets

仓库管理是工业、企业生产管理不可缺少的一环。传统的仓库管理工作中的信息管理是采用人工的方式，要付出大量人力，填写各种表格、凭证、账册、卡片和文件。由于信息是随着时间不断变化的，所以仓库数据要按照不同的分类经常不断地汇总、统计，往往要做许多重复登记和转抄。这种手工操作的管理方式，不仅浪费人力，而且存在着处理速度慢、易出现错误、不便于查询及缺乏综合性等缺点。因此，大大降低了信息的利用价值，很难适应现代仓库管理工作的需要。随着计算机技术和自动化技术的发展，仓库管理也越来越智能化、科学化。建立完备的仓库计算机管理系统是企业进一步优化管理模式，提高企业竞争力的必要手段。 基于上述背景分析，本文以社区超...Warehouse management is an indispensable part of industry and enterprise production management.

Research on the Key Techniques of DFT-SOFDM Underwater Acoustic Communication System and the Implementation Based on DSP

长的传输时延、多普勒扩散、频率选择性衰落以及有限的可用带宽等诸多因素，决定了水声通信信道的复杂性。然而20世纪以来，由于军用和民用的需求，水下通信技术开始被广泛研究。当今社会对高速率的传输系统的需求也日益迫切。多载波调制技术被认为是高速水下通信的一种备选方案，其中最常用的是正交频分复用(OFDM)技术。但是，OFDM技术本身有一些缺陷，其中之一就是具有较高的峰值平均功率比。 本文研究了一种适用于在水声信道中使用的DFT扩展正交频分复用(DFT-SOFDM)技术，它不仅具备传统的OFDM的优势，而且具有更低的峰值平均功率比。本文着重研究DFT-SOFDM的关键技术及其DSP实现。计算机仿真结果...The complexity of underwater acoustic communication channel is driven by the ocean environment characteristics, including large delay, Doppler-spreads, frequency-selective fading and limited bandwidth.

The Process of Shaping Female Performers' Body in Tourist Sites: Based on the Observation of Performance at L Theatre in Guangxi Province

随着旅游业的发展,实景演出剧场作为新旅游空间,招募了大量非少数民族青年女性从事少数民族歌舞表演。文章以身体为出发点考察这些女性表演者的社会型塑:女性表演者身体在市场的性别化消费逻辑下,经由组织制度化的时空运作以及组织中的身体规训而被型塑,成为了具有消费性、生产性以及民族文化性的身体,从而揭示旅游演艺将民族文化化约为隐匿在其背后的传统性别秩序与社会性别角色。With the development of tourist industry, real live performance theatre has been created on site.A large number of Han women are recruited to perform dances of ethnic minorities.This paper uses the body as a starting point to investigate the social construct of gendered body, recognizing that women performers' body is socially constructed in the context of gendered consumption, through the space and time of institutional rules of an organization.The private and ordinary body has become a productive, consumable and ethnic cultural body, which conveys a traditional gender order with gendered roles hidden behind the touristic performing art

Study on the rheology of xanthan and synergistic interaction with konjac gum and other gum

研究前期筛选获得一株多糖胶质高产菌Xanthomonas axonopodis所产的黄原胶FJAT-10151-DTJZ的品质,为该黄原胶的开发应用提供基础数据及参考。通过分析浓度、剪切速率、p H、加热温度、时间、冻融处理等对FJAT-10151-DTJZ粘度的影响研究其流变性,并研究其与结冷胶、黄原胶、凝胶多糖、瓜尔豆胶、刺槐豆胶、魔芋胶、果胶和壳聚糖8种胶的协效性。实验结果表明,FJAT-10151-DTJZ溶液的粘度随浓度的升高而升高,且为非牛顿流体;当FJAT-10151-DTJZ的浓度为1%时,其粘度为343 m Pa·s;p H、冻融对FJAT-10151-DTJZ的粘度影响不大;FJAT-10151-DTJZ的最佳加热温度为75℃;粘度随加热时间先增大后减小,当加热温度为75℃,加热时间为150 min,1%浓度的FJAT-10151-DTJZ溶液的粘度为808 m Pa·s。FJAT-10151-DTJZ只与魔芋胶有强烈的协同增效作用,与壳聚糖、结冷胶、黄原胶、凝胶多糖、瓜尔豆胶、刺槐豆胶、果胶无协效性。A Xanthomonas axonopodis strain producing xanthan gum had been screened,and researched the quality of xanthan gum FJAT-10151-DTJZ in order to provide basic data and reference for development and application. The rheology properties of FJAT-10151-DTJZ were discussed according to the viscosity variation with different conditions including concentration,shearing,p H,heating temperature,heating time and freezingthawing. The synergistic interactions of FJAT-10151-DTJZ with chitosan,gellan gum,xanthan gum,curdlan,guar gum,locust bean gum and pectin were also investigated. The results showed that polysaccharide gum solution FJAT-10151-DTJZ was non-Newton fluid. It's viscosity rised with its concentration and reached to343 m Pa·s when the concentration was 1%. The p H change and freezing-thawing played negligible effects on its viscosity. Its viscosity was 808 m Pa·s when it was heated at 75 ℃ for 150 min. Besides,FJAT-10151-DTJZ had no synergistic interaction with chitosan,gellan gum,xanthan gum,curdlan,guar gum,locust bean gum and pectin except konjac gum.国家948项目(2014-Z48);; 福建省公益类科研院所专项(2015R1018-2);; 福建省农业科学院科技创新项目(2015CX-7
