Interpersonal attraction and personality: What is attractive--self similarity, ideal similarity, complementarity or attachment security?

Little is known about whether personality characteristics influence initial attraction. Because adult attachment differences influence a broad range of relationship processes, the authors examined their role in 3 experimental attraction studies. The authors tested four major attraction hypotheses--self similarity, ideal-self similarity, complementarity, and attachment security--and examined both actual and perceptual factors. Replicated analyses across samples, designs, and manipulations showed that actual security and self similarity predicted attraction. With regard to perceptual factors, ideal similarity, self similarity, and security all were significant predictors. Whereas perceptual ideal and self similarity had incremental predictive power, perceptual security's effects were subsumed by perceptual ideal similarity. Perceptual self similarity fully mediated actual attachment similarity effects, whereas ideal similarity was only a partial mediator.

再论异重流和均质流动的一些相似关系

在对上层静止下层流动的异重流和均质明渠流之间相似关系研究的基础上，本文将这一成果推广，给出了上层流动下层静止的异重流和均质明渠流之间的一些相似关系，并将结果应用于二维重叠式排取水口的水深计算，结果与前人的实验一致。考虑到实际的重叠式排取水口都是三维的，所以本文利用前人的实验结果，进一步给出了三维重叠式排取水口高度及水深的计算方法，所得结果揭示了排水口温差水跃的形成机理和形成条件。

两性淀粉的制备及表征

以正磷酸盐为阴离子化剂,对高取代度的阳离子淀粉进行改性,制备阴阳离子比为0.5的两性淀粉,其最佳工艺为:磷酸盐与阳离子淀粉质量比为1.94～2.02.反应温度145～155℃,反应时间3～3.5 h。用红外光谱、X射线衍射、扫描电镜对其结构进行了表征,结果表明此种两性淀粉仅使淀粉结构中的非晶态区发生改变,并未改变整体结晶结构,因此其生物降解性会同天然高分子淀粉一样可完全降解。

The minimum squared euclidean distance of multi-h phase codes

The minimum squared Euclidean distance(MSED) of binary multi-h phase codes is presented. The signal segregation degree(SSD) has been put forward to determine MSED of multi-h phase codes. In order to maximize MSED, SSD should be as large as possible. The necessary and sufficient conditions of maximizing SSD are derived. Finally, SSD and the exact formulae for MSED of binary 2-h phase codes are also presented.     

Effect of thermomechanical treatment on mechanical properties and electrical conductivity of a CuCrZr alloy

The CuCrZr alloy undergoes processes of precipitation during ageing. Besides precipitation hardening the strength is affected by cold deformation which is performed before and after ageing. The cold deformation (D ₁) before ageing accelerates the process of strength hardening, since it induces higher rate of precipitation from the saturated a-sold solution. Cold deformation (D ₂) after ageing primarily affects the alloy strength. In this paper the results of the effect of thermomechanical treatment on mechanical properties and electrical conductivity of a CuCrZr alloy are presented. The aim of the paper was to evaluate the most suitable combination of thermomechanical treatment and alloy properties.
