Culture and group perception: Dispositional and stereotypic inferences about novel and national groups.

In 3 studies, the authors tested the hypothesis that Chinese participants would view social groups as more entitative than would Americans and, as a result, would be more likely to infer personality traits on the basis of group membership--that is, to stereotype. In Study 1, Chinese participants made stronger stereotypic trait inferences than Americans did on the basis of a target's membership in a fictitious group. Studies 2 and 3 showed that Chinese participants perceived diverse groups as more entitative and attributed more internally consistent dispositions to groups and their members. Guided by culturally based lay theories about the entitative nature of groups, Chinese participants may stereotype more readily than do Americans when group membership is available as a source of dispositional inference.

Study of trace elements in coal and mining wastes and its significance in China

In the world energy about 26% of all was dedved from coal combustion. Nearly 80% of the electricity produced in China is generated from coal. Coal will play the most important role in the coming 50 years as the past century in China. However one consequentially of the mining and combustion of coal is the mobilization of trace elements, especially trace metals, which have environmental and human health significance. Information on concentrations and distributions of potentially toxic elements in coal, and information On the modes of occurrence of these elements and the relations of the minerals in coal can help to predict the behavior of the potentially toxic trace metals dudng cleaning, combustion, weathering, and leaching.     

Congruences and ideals in pseudoeffect algebras

This paper is devoted to congruences and ideals in pseudoeffect algebras. Let I be a normal ideal in a pseudoeffect algebra E. We show that: (1) the relation ~ _I induced by I is a congruence if and only if for every a∈E, I∩ [0,a] is upper directed; (2) the relation ~ _I induced by I is a strong congruence if and only if I is a normal weak Riesz ideal in a pseudoeffect algebra E. Moreover, we introduce a stronger concept of congruence—namely Riesz strong congruence—and we prove that, if I is a normal weak Riesz ideal in a pseudoeffect algebra E, then ~ _I is a Riesz strong congruence and, conversely, if ~ is a Riesz strong congruence, then I = [0]_~ is a normal weak Riesz ideal, and ~ _I = ~.

现代超细粉碎技术在刺五加生产中的应用

阐述了现代超细粉碎技术基本原理及特点及其在刺五加生产中的应用,论述了在相同压力不同转速下和压缩空气压力以及破碎次数对粒度分布特性的影响。通过实验数据分析得出以下结论:破碎粒度随着压力的增大而减小,但当压力增大到一定值时,破碎粒度反而增大;随着转速的增大,破碎粒度变小;随着破碎次数的增加,粒度分布范围变窄,随后又变宽。     

强潮河口桩式丁坝减冲促淤效果研究

钱塘江涌潮气势雄伟,世界闻名,但对海塘具有很大的破坏力.该文提出了一种新颖的丁坝型式——桩式丁坝,从现场观测资料对比、实体模型试验和机理分析三个方面,分析桩式丁坝的减冲促淤效果,探究丁坝护滩保塘的机理.与堆石丁坝比较,桩式丁坝具有设计合理、施工简易、坝体内无内压力、有效地减轻了局部冲刷、便于维护检修等一系列优点。桩式丁坝可广泛应用于各类河道整治、海塘保护等工程中.     

调理心肾中药对拟痴呆大鼠脑组织中M和GABA受体功能的影响

以~3H-QNB和~3H-GABA为放射性配基,用受体放射性配基结合分析法,测出拟痴呆模型大鼠大脑皮层和海马组织中的M受体和小脑组织中的GABA受体的R_t值明显降低;M受体的K_D值在大脑皮层中明显减少,在海马中略有升高。小脑中GABA受体的K_D值显著降低。调理心肾中药及喜德镇(Hydergin,为国外常用抗老年痴呆药)能使降低的M受体和GABA受体的R_t值均明显升高,接近正常水平。对K_D值则有不同程度的调整作用。
