谈"X跟Y一样W"语式的语义预设

“X跟Y一样W”语式的语义预设相当复杂,但呈现出严格的规律。该语式在表示比拟的意义时,存在“YW”的预设义;在表示比较的意义时,其语义预设与“W”的性质有关:当“W”不是“大、小”类词时,存在着“YW”的预设义;当“W”是“大、小”类词的消极成分时,同样存在着“YW”的预设义;当“W”为“大、小”类词的积极成分时,不一定具有“YW”的预设义。也就是说,并不预设事物具有积极成分的概念意义所表达的性质,而是表示整个概念范围。     

关于行将到来的美国对伊拉克战争

“9·1 1”事件发生后 ,美国政府就强烈倾向在取得阿富汗战争胜利后进入反恐战争“第二阶段” ,而这个阶段被设想和规划的首要内容 ,便是实现解除伊拉克武装和变更伊拉克政权。在布什的心目中 ,发动这场战争关系到美国的眼前和长远安全 ,关系到美国的世界霸权或准霸权地位 ,外加其他一些地缘政治、地缘战略和地缘经济目的以及布什本人的国内政治利益。然而 ,美国无法解决阿拉伯世界的深层问题     

The literature of educational psychology and the literature used by writers in educational psychology

Using Psychological Abstracts as the source of the original sample (“first-level”), various characteristics of the literature of educational psychology are compared with the characteristics of a “second-level” literature (defined as the literature that the first level cites). In particular, the scatter (dispersion) of periodical articles over periodical titles is looked at for both levels. The journals most cited within the literature of educational psychology are identified.     

A comparison of sentence-learning errors in children of different achievement levels

Theoretical analyses of the multiple-choice test format suggest that a test constructor should give serious consideration to the form in which correct and incorrect alternatives are presented. In this experiment, third and fourth graders were tested for previously exposed information by multiple-choice items in which: (a) correct alternatives were stated in either verbatim or synonym form; and (b) incorrect alternatives consisted of plausible responses that were either familiar or new. Comparisons of errors and error patterns were made between high and low achieving students who had been given one of two different information-processing strategies. Based on a dual test function argument, it was concluded that synonym correct alternatives combined with plausible new responses are the most desirable of the four multiple-choice variations studied here. In particular, such items were sensitive to achievement level and strategy differences without systematically increasing students' likelihood of retaining misinformation.     

多功能红外语音体温计的设计

介绍一种具有非接触体温测量的新型多功能红外语音体温计。该体温计基于普朗克黑体辐射定律和高性能红外温度传感器,采用单片机数据处理和语音处理、LCD显示等技术,能够对体温进行有效准确的非接触测量。该体温计功耗低,测量速度快,并有年历、语音报温和报时,安全可靠,使用方便等特点,可广泛应用于日常保健及医学测试领域。     

追求沉思还是体验快感:流行音乐再思考——试析阿多诺的流行音乐批判理论

标准化与伪个性化、精神涣散与听觉退化是阿多诺考察流行音乐时形成的两个著名结论 ,但是他的这种判断却遭到了西方学者的质疑与批判。实际上 ,阿多诺对流行音乐的仇恨既是其文化工业批判理论总体思路的具体延伸 ,同时也是他本人的情感好恶所致 ,而更重要的是 ,流行音乐主要是诉诸于听众的身体狂欢而不是他们的心灵沉思 ,因此 ,阿多诺对流行音乐的定罪存在着明显的错位 ,他与流行音乐的交战实际上是两种美学观念之间的冲突     

毛茛科金莲花族和升麻族细胞学的比较研究

对毛茛科金莲花族Trolliese和升麻族Cimicifugeae的细胞学进行了比较研究。发现驴蹄草Caltha palustris L．在云南西北部形成一个多倍体系列(2n=32，48，64)，四倍体细胞型(2n=4x=32)较为常见，其核型有明显的居群间变异。驴蹄草属Caltha、鸡爪草属Calathodes、Megaleranthis以及金莲花属Trollius的染色体在大小上基本相似，都属于中等大小的R-型染色体。细胞学和花粉学证据都支持鸡爪草属与Megaleranthis和金莲花属有较近的亲缘关系。铁破锣属Beesia、Anemonopsis、黄三七属Souliea、升麻属Cimicifuga以及类叶升麻属Actaea的核型彼此基本相似，在染色体大小和形态上都与驴蹄草属、鸡瓜草属、Megaleranthis以及金莲花属的核型明显有别。细胞学证据表明铁破锣属应是升麻族中的成员。
