    偏误研究是汉语作为第二语言教学的重要课题,也是近年来对泰国学生汉语习得研究的一个热点问题;同时,随着语言学家对学习者的心理动机愈发重视,学习者的学习策略研究也引起了学者浓厚的兴趣。笔者将两个重要方面结合起来——从学习策略视角对汉语偏误进行研究,探讨学习策略对泰国大学生汉语习得过程中产生偏误的影响。为了达到该研究目的,本文做了大胆的尝试,一是笔者搜集泰国大学生的汉语写作文本,并且使用北京语言大学HSK动态语料库作为偏误研究参考;二是为了更真实地贴近泰国大学生汉语习得现状,笔者对该群体的学习策略进行了问卷调查、习得观察和当面访谈;三是使用教学课堂对学习者进行学习策略的相关培训。在这三个研究基础上,...Error in Chinese is not only an important issue in a second language teaching, but also as a hot issue for Thai students studying Chinese in recent years. Similarly, linguists found that psychological motivations of learners were increasingly important, strategy learning also attracted great interest of scholars. This paper combined two important aspects from the perspective of Chinese language le...学位:文学博士院系专业:人文学院_语言学及应用语言学学号:1022012015409

    本文应用dEndrInOS-SOnIS模型分别对厦漳泉大都市区内部厦漳泉三市、泉州八市县和漳州十市县三次产业发展的竞争互补性进行了实证检验,结果表明中心城市厦门在三次产业中都没有很好地发挥其应有的辐射作用。三市在第二产业上都表现为竞争关系。泉州在第一产业和第三产业的发展上对于漳州是有促进作用的,而漳州在第一产业上的发展对泉州第一产业也有促进作用。泉州八市县,在第一产业上更多地表现为互补关系,第二产业则竞争互补参半,第三产业更多地表现为竞争关系。漳州市十市县较厦漳泉三市以及泉州八市县而言其竞争互补性最弱。福建省质量技术监督局科技项目(FJQI2013116

    塔玛亚历山大藻(Alexandrium tamarense)是一种有毒甲藻,常引发赤潮,对海洋环境及人类健康造成极大的威胁.前期研究发现,耐辐射球菌属的一株细菌Y35能够通过分泌杀藻化合物Deinoxanthin达到控制塔玛亚历山大藻生长的效果.为了加强Deinoxanthin的应用效果,对其在不同条件下的稳定性进行了研究.结果表明,杀藻化合物Deinoxanthin有较高的热稳定性,且在中性和碱性条件下稳定,在光照和紫外线辐射下易分解.而通过壳聚糖和海藻酸钠对Deinoxanthin进行包埋固定化,从而构建缓释微球提高了Deinoxanthin的稳定性.杀藻制剂能够高效地表现出杀藻效果,杀藻制剂的研发为杀藻细菌色素应用于藻华治理奠定了基础.Alexandrium tamarense is a toxic dinoflagellate,capable of forming harmful algal blooms( HABs),and poses a substantial threat to both the marine environment and human health. Our previous research found Deinococcus sp. Y35 could secret algicidal pigment deinoxanthin which showed efficient algicidal effect on A. tamarense,resulting in controlling the growth of A. tamarense. In order to enhance the algicidal effect of deinoxanthin,the stability of deinoxanthin under different conditions was investigated. The results show that the thermal stability of deinoxanthin was high and remained stable under neutral and alkaline conditions,yet was prone to decompose in the light and ultraviolet radiation. The stability of deinoxanthin was improved after immobilization by chitosan and sodium alginate. The algicidal agent could exhibit high algicidal effect on A. tamarense,laying the foundation for the application in the control of HABs.国家自然科学基金(No.41576109,31400318);; 河南师范大学博士科研启动基金(No.5101049170160)~

    在悬挂吊车作用下,螺栓球节点网架的疲劳主要表现为节点的疲劳,而节点的疲劳关键是高强螺栓的疲劳.在影响高强螺栓疲劳性能的众多因素中,应力集中是其发生疲劳断裂的主要原因之一.本文从缺口效应出发,分析了高强螺栓疲劳裂纹的开展,并建立有限元模型,针对钢网架螺栓球节点常用的8种高强螺栓规格进行了单缺口应力集中分析,得到相应的应力集中系数,同时分析了螺纹牙根圆角半径对应力集中的影响,并提出了降低螺纹疲劳缺口敏感性的一些措施,为进一步以热点应力幅建立螺栓球网架疲劳设计方法奠定了基础.Fatigue often occurs at joints for the grid structure with bolt-sphere joints(GSBSJ)loaded by suspension crane,especially for high strength bolts.Among many factors that cause fatigue fracture of high strength bolts,stress concentration is a dominant one.In this paper the fatigue crack growth in bolts is first presented.Then the single notch stress concentration for eight different kinds of bolts currently used in grid structures is studied based on finite element method.The influence of the bottom radius of screw thread on stress concentration is also discussed.To reduce the sensibility of notch in screw,some feasible methods are presented.The stress concentration coefficients obtained in the present study provide a foundation to further study and design GSBSJ using "hotspot stress amplitude"

    A Bioinspired Tilt Sensor Model with Adaptive Gain and Enhanced Sensitivity

    Natural Science Foundation of Fujian Province of China [51308482]; Science and Technology Key Project of Fujian Province of China [2013Y0079]Although various types of tilt sensors have been proposed in the past decade, it is still essential to develop rugged, cheap, simple-structured tilt sensors with wide measuring range and high sensitivities for efficient monitoring of infrastructures and early warning of natural disasters. It has been investigated that stereocilia in some fishes' inner ear organs are the basic sensory units of nature's inertial sensors and are highly sensitive over broad dynamic range because of a combination of adaptation and negative stiffness mechanisms. In this paper, a bioinspired tilt sensor model is proposed that mimics the mechanism of stereocilia in adaptive signal amplification to mechanical stimuli, leading to high sensitivity to weak input and low sensitivity to high input, thus expanding the dynamic range through adaptive amplification. The negative stiffness mechanism is implemented by magnet forces. The tilt motion is measured by the strain gauge at the end of the flexible cantilever beam element in the model. Measurements of both static and dynamics tilt motion are investigated. Numerical simulation results are used to demonstrate the capability of the proposed model for the measurements of tilt motions with adaptive amplification and enhanced sensitivity
