大学英语课堂教师话语调查研究

教师话语在组织课堂教学和语言习得中起着根本性作用。由对周口师范学院150名学生问卷调查和对6位外国语学院教师的访谈发现:教师话语量明显大于学生话语量;教师话语输出较形式化,话轮转换较机械;教师话语中的展示性问题较参阅性问题多;课堂反馈简单积极,惯用直接纠错等。基于此,从教师角色、课堂提问方式、语速把握、师生互动等方面提出改进大学英语教师话语的措施,以期有助于教师调节和规范自己的课堂语言,提高大学英语课堂教学效果。     

虫媒登革病毒的研究——Ⅱ.登革病毒非结构蛋白NS1的纯化、鉴定及其在临床检测应用

本文从纯化Den2 NS1,Mab入手,自制了Mab亲和层析系统,从感染Den2的细胞膜中,分离提取了天然的Den 2 NS1双体,比较其NGC株与我国地方株(H-87)NS1的理化性质及组成,并对某些重要的生物学性质进行了综合性研究。同时,利用上述研究结果建立了检测DF病人血清特异NS1抗体的新方法,探索其协助临床诊断及研究的可能性。

Clinical detection and movement recognition of neuro signals

INTRODUCTION Human limbs are complex, delicate systems.Their reconstruction, both for appearance and forfunction compensations, proves to be complicatedprojects. With the development of science and tech-nology, both researchers and disabilities hope to haveartificial limb much more perky, comfortable, dex-terous and effective. Although thousands of pros-thetic limbs are commercially available worldwide,most of them, from mechanical styles to electricstyles, from motion controlled t…     

A symplectic eigensolution method in transversely isotropic piezoelectric cylindrical media

INTRODUCTION Since the phenomenon of piezoelectricity in natural crystals was discovered in 1880, it has been applied in many fields, such as smart structure, sensing devices and active control, because of its special properties. Combining electrical behavior with mechanical deformation is the special property which attracted great interest of researchers. Many models have been developed for studying piezoelec- tric effects. Dunn and Wienecke (1996) used Green’s functions for transverse…

大学与产业科研合作的权益保障机制研究

大学与产业科研合作涉及到的相关利益主体有大学、研究者及产业。大学与产业科研合作基于自愿、平等和互利的原则,但相关利益主体的基本权益保障是合作的前提。为确保产学科研合作顺利、有序、健康地发展,产学科研合作必须建立和完善权益保障机制,包括严密的保密机制和严格的技术合同管理机制。     

Consolidation behavior of cement- and lime/cement-mixed column foundations

The consolidation behavior of mixed in place cement- and lime/cement-mixed column was studied. Consolidation of the composite foundation was modeled as a three-dimensional axi-symmetric problem. The authors used the finite difference method to obtain the pore pressure variation with time at any location below the surface. A computer program developed by the authors was used to draw some interesting conclusions about the consolidation behaviors of cement- and lime/cement-mixed pile foundation. Finally, a combined model including the permeability coefficients of cement-mixed piles and soil, was studied and its feasibility was evaluated.
