A Study of Chinese Urban Married Female Labor Force Participation Rate during the Market Transition Process

建国初期，我国实行计划经济体制，社会劳动力得到广泛动员，劳动参与率非常高。二十世纪九十年代中国经济转型时期，城镇已婚女性的劳动参与率出现了明显的下降趋势，并且与男性之间的差距越来越大。这一现象引起人们的关注。中国经济转型时期城镇劳动力市场发生了什么突出变化？已婚男性与女性劳动参与呈现出什么样的变化趋势？哪些群体在退出劳动力市场？是哪些因素在影响女性的劳动参与？家庭因素在其中又起到一个怎样的作用？ 本文使用我国15个省份1988-2006年的城镇家庭收入支出调查（UHIES）的数据来研究城镇已婚女性在这将近二十年间劳动参与率的变化特点及其影响因素，特别关注宏观经济事件和家庭在其劳动参与决策中起...In early times, China experienced a centrally-planned economy when people were encouraged to participate in the working community. So both married men and women in urban area had an extremely high labor force participation rate. During the market transition process, the female labor force participation rate began to decrease continuously which has drawn much attention. People want to know what has...学位：经济学硕士院系专业：王亚南经济研究院_劳动经济学学号：2772012115263

木聚糖酶原位协同水解预处理大米草的研究

实验主要研究了氨水/双氧水结合球磨预处理对重组木聚糖酶协同水解大米草的增强效果。首先使用氨水与双氧水预处理大米草，预处理物与原料大米草随后用于球磨。然后将预处理底物分别用于结构表征及木聚糖酶的协同酶解。结果说明氨水结合双氧水预处理能有效脱除大米草中的木质素(63.81%)，球磨处理能对纤维素结晶结构有所破坏，两者有效提高木聚糖酶的水解率。而经预处理过的大米草的酶水解物主要成分为木糖(12.54%)，木二糖(40.38%)，及少量阿拉伯糖(5.50%)。以上结果说明碱预处理结合球磨预处理对后续木聚糖酶协同水解大米草产木寡糖具有明显的促进作用。厦门大学能源发展基金(2018NYFZ03

三维双楔面定常激波相互作用

本文通过理论分析,将三维对称双楔面上定常激波相互作用简化到二维截面进行分析,利用二维非定常激波楔面反射理论求解该三维激波相互作用结构。同时,通过采用二阶精度的NND格式求解三维Euler方程,对该理论分析结果做出数值模拟验证。理论分析和数值模拟结果显示,对于三维双楔面超声速定常流动在取定的二维截面上激波结构兼有二维非定常及定常激波反射的性质,即形成了类似于二维非定常激波楔面反射的规则反射、单马赫反射、过渡马赫反射及双马赫反射等结构,同时其规则—马赫反射转变却遵循适用于二维定常激波反射的von Neumann准则。理论分析得出的各种反射结构的存在范围与数值模拟结果吻合良好。同时,探讨了两楔面间夹角以及楔面前缘后掠角对该激波结构的影响

Study on the University Freshmen's Mal-adaptation and Self-adjustment

大学新生在步入大学校园后,面对全新的生活环境和角色转换,常会产生各种适应不良情况。现阶段大学新生存在的适应问题表现在心理状态、发展目标、学习过程和生活方式四个纬度。有鉴于此,大学新生应从四个方面进行自我调适:心理状态实现由依赖变为独立,发展目标实现由高考应试转为能力培养,学习方式实现从被动转向主动,生活方式从他律转入自律。Mal-adaptation for university freshmen when facing new campus life is a hot issue currently.The psychological state,development goals,learning process and the way of life are the four main dimensions of mal-adaptation among freshmen.The corresponding self-adjustment may help freshmen adapt to the new environment and the role changed on campus.The following are the suggestions:the change of mental state from dependence to independence,the change development target from the college entrance examination to training ability,the change of learning from passive to initiative and the change of lifestyle from heteronomy to autonomy

新加坡初级学院学生华语助词的使用情况 = The use of Mandarin particles by Singapore junior college students

有关汉语助词中的“了、过、着”，许多学者都有所研究（如 Chao，1968；Li & Thompson，1981；Huang & Shi，2016），然而较少关注这些助词在普通话以外的汉语变体中的使用。本文专注于新加坡书面语中的助词，以本地初级学院学生的作文为语料，通过观察，进一步考察学生对“了、过、着”的掌握程度，分析其偏误的类型， 从而深入了解这些助词在新加坡华语中的使用情况。本研究主要有三大发现：一、“了”的主要偏误是“多余”使用，其中“了 1” 占绝大部分；二、“过”的使用频率极低；三、“着”的主要偏误也是“多余”使用，学生倾向把它当作英文的进行时标记。本文的研究可以为新加坡学生在助词习得上提供一些参考。 Many scholars had done research on the Mandarin particles "le, guo, zhe" (Chao, 1968； Li & Thompson, 1981；Huang & Shi, 2016). However, few studies have focused on the use of these particles in Sinophone world. This paper focuses on the written form of Mandarin particles in Singapore, the composition of local junior college students is used as the corpus. Through observation, this paper further investigates the students' mastery of "le, guo, zhe" and analyzes the types of errors, so as to understand the usage of these Mandarin particles in Singapore context. There are three major findings in this study: 1. The main error of "le" is "redundant", of which "le1" accounts for the majority; 2. The frequency of usage of "guo" is extremely low; The main error of "zhe" is also "redundant", students tend to regard it as a marker equivalent to English progressive. This paper will serve as a reference for studies on the acquisition of Chinese particles.Bachelor of Arts in Chines
