从英汉反复修辞格看冗余信息

冗余现象在语言中是普遍存在的,英汉反复修辞就是冗余信息在语言运用中的一种表现。英汉反复修辞有各种不同的表现形式,每一种形式都具有冗余的特点。通过分析各类反复中因冗余信息带来的语用修辞效果,从修辞的角度来证实冗余信息存在的必要性和合理性。     

Mutagenic effects of chromium trioxide on root tip cells of <Emphasis Type="Italic">Vicia faba</Emphasis>

In this study on the mutagenic effects of different concentrations of chromium trioxide (CrO₃) on Vicia faba root tip, micronucleus assay and chromosome aberration assay were used to determine the mitotic indexes, micronucleus rate and chromosome aberration rate of Vicia faba root tip cells. The results showed that the effects of CrO₃ concentration on the mitotic indexes were complicated. CrO₃ increases the micronucleus rate of Vicia faba root tip cells. It was found that within certain range of CrO₃ concentration the micronucleus rate increased systematically with increased concentration of CrO₃, but that the micronucleus rate decreased at higher level of CrO₃ and that CrO₃ also caused various types of chromosome aberration at a rate which increased systematically with increased concentration of CrO₃. We concluded that CrO₃ has significant mutagenic effect on Vicia faba root tip cells.

对大众化高等教育质量观的认识

对目前高等教育界流行的主要的质量观进行分析和概括,认为,大众高等教育必然出现多样的高等教育质量观,否则高等教育只能停留在精英阶段而不能发展.而这些不同的质量观,都是在一定程度上、一个侧面反映人们对高等教育质量的认识,它们是辩证统一体.在高等教育大众化发展过程中,应以多样高等教育质量观为指导,建立多样化的评价系统,促进高校的多样化发展.并进一步指出,树立多样高等教育质量观,绝非不要关注当前高等教育存在的质量问题,高等教育质量始终是高等教育的生命线.     

生物质炭对菜地土壤甲烷和氧化亚氮及二氧化碳排放的影响

以菜地土壤为供试土壤,通过室内盆栽试验,研究不同生物质炭原料（毛竹粉、稻草）、不同生物质炭添加量（0.5%、1%干土）对土壤甲烷、氧化亚氮和二氧化碳排放的影响。试验结果表明,与不添加生物质炭相比,添加生物质炭可以有效减少土壤温室气体的排放;其中相同添加量的稻草炭的有效性高于毛竹炭;相同原料的生物质炭其添加量越多,温室气体排放量越小;在生物质炭施加初期,对甲烷排放的影响较少,但随着时间推移,影响效果增强,而对氧化亚氮、二氧化碳排放的影响正相反;生物质炭对氧化亚氮的影响强度高于甲烷与二氧化碳。

金属材料弯曲和扭转真实流动极限的实验研究

通过选取黄铜(Hb2)、优质结构钢(45#)、普通低合金钢(16Mng)、合金钢(Icr13)、铝合金(Lr12)五种金属材料，用不同的截面形状和加载速率对其流动极限进行试验研究。理论分析和实验结果表明：在不同的材质、加载速率和截面形状条件下，应力分布不均匀对流动极限的影响很小，并能够忽略，因此可以认为，金属材料的流动极限是一个固有的物理常数，应力分布不均匀对其几乎没有什么影响。     

Anatomical studies on water hyacinth (Eichhornia crassipes (Mart.) Solms) under the influence of textile wastewater

Water hyacinth (Eichhornia crassipes (Mart.) Solms) is a prolific free floating aquatic macrohpyte found in tropical and subtropical parts of the earth. The effects of pollutants from textile wastewater on the anatomy of the plant were studied. Water hyacinth exhibits hydrophytic adaptations which include reduced epidermis cells lacking cuticle in most cases, presence of large air spaces (7∼50 μm), reduced vascular tissue and absorbing structures. Textile waste significantly affected the size of root cells. The presence of raphide crystals was noted in parenchyma cells of various organs in treated plants.

知识嫁接学说：一种更具包容性的教学理论

人类知识的传承主要是通过其特有的教与学系统而实现的。以往各种教与学理论只是从不同的角度和侧面阐述了教育教学的部分本质。知识嫁接学说试图综合各种教与学的理论成果,从更开阔更全面的视角来阐释教学的过程和本质。该学说认为,人类的个体知识就像一棵具有三级结构的＂榕树＂,教育教学的过程就是对知识树实施＂嫁接＂的过程。在网络时代,知识嫁接越来越呈现出碎片化的趋势,这就要求我们在知识嫁接的过程中,应特别关注知识之间的亲和力,掌握知识嫁接的时机,对不同种类的知识采用不同的嫁接技术。在人类知识的传承过程中,复制与模仿是知识嫁接的重要方式之一,知识嫁接成功的标志就是知识由短期记忆转变为长期记忆。今天的教育教学应该将自下而上的学习与自上而下的学习结合起来,以最终实现知识创新的目标。     

壳聚糖对菘蓝根腐病病原菌抑制作用的研究

从唐山师范学院花房中采集菘蓝根腐病病根并对其进行了病原菌的分离、纯化和鉴定及不同浓度、不同分子量的壳聚糖对菘蓝根腐病病原菌的室内抑菌作用。结果表明：分离纯化得到致病菌经鉴定为半知菌亚门（Deuteromycotina）、丝孢纲（Hyphomycetes）,丛梗孢目（Stilbellales）、瘤座孢科（Tuborculadales）、镰刀属（Fusarium）真菌。在一定浓度范围内,分子量为3KD、50KD的壳聚糖随着浓度的提高,其抑菌效果也逐渐增强,6mg／ml的效果最好;分子量为150KD时,3mg／ml的效果最好;在一定分子量范围内,除0．75mg／ml的浓度外,随着壳聚糖分子量的提高,其抑菌效果也逐渐增强,分子量150KD的效果最好;本试验中,最大抑菌率为61％。     

Retrieval-based learning in special education

Retrieval-based learning has been investigated in various populations. The present study examined retrieval-based learning in a sample of students at a special-needs school with educational tracks for learning and mental development. In addition, a comparison group of students at a regular school was examined. Learning conditions were manipulated within participants. In a first session, participants either received restudy cycles only, or they received alternating test and restudy cycles. A second session then comprised the opposite form of practice. In both sessions, a final test assessed memory after a short distractor phase. This procedure was the same in two experiments but with different kinds of item material. For both kinds (images and image-word pairs), a testing effect occurred, that is higher recall of tested items. These results show that lower cognitive ability or lack of experience with regularly being tested in school do not prevent students from benefiting from retrieval-based learning.     

Development of a Concept for Quality Management in Engineering Education

Due to the fact that the quality area has its roots firmly established primarily in the statistical research tradition, its rapid and extensive development mainly towards the management‐oriented area has created different kinds of problems. This paper discusses different consequences of this development. The paper further describes how quality issues are treated in various types of educational scenarios at the College of Applied Engineering and Maritime Studies at Chalmers University of Technology.     

发展性阅读障碍的跨文字一致性和特异性

本文分析了不同文字记录语言方式的差异,并根据这一差异,对不同文字中发展性阅读障碍的发生及其不同表现和不同类型进行了综述。发展性阅读障碍是跨文字普遍存在的现象,又具有一定的文字特异性;不同文字阅读障碍在语音加工、阅读速度和亚类型方面均存在一致性和区别性。针对不同的语言文字特点,进行跨语言对比研究,并结合双语者阅读障碍的研究有助于得出关于阅读障碍的跨文字的一致性和特异性的更为可靠和有意义的结论。
