化学配比对TiAl有序合金微观组织和变形特性的影响

本研究用三点弯曲实验测定了铝含量为43at·％～56at·％的Ti-Al二元合金的力学性能;利用光学显微镜、X射线衍射仪和透射电子显微镜研究了不同成分合金的微观组织和变形亚结构。实验结果表明:根据不同成分合金的微观组织可将其分成三类,即:γ-TiAl单相组织(52at·％～56at·％Al);双态组织(46at·％～50at·％Al)和全片层结构晶粒组织(43at·％～46at·％Al),其中以具有细晶双态组织的合金具有较好的塑性变形能力。本文从微观组织结构和变形位错组态的变化,探讨了合金成分对TiAl基有序合金塑性变形的影响机制。

WHOLLY-AROMATIC COPOLYESTERS CONTAINING IPA, 2.6-NDA, TPA, CLHQA AND PABA MONOMERS

The crystallinities, thermal properties, liquid crystal properties and rheologic properties oftwo series of the aromatic copolyesters are studied. One of them is composed of IPA, 2,6-NDA,CLHQA, PABA and. the other composed of TPA, 2.6-NDA, CLHQA, IPA. The results showthat the crystallinities of the aromatic copolyesters are relatively low and the melting point of thecopolyesters decreases with an increase of the unsymmetrical contents. These two series of aro-matic copolyesters are both suitable for the conventional melt spinning process and have a goodfiber forming property and a good thermal stability. The viscosities of aromatic copolyestermelts are greatly affected by the shear rate, hence the so-called" thinning under shearing" phe-nomenon. The melts have a rather high viscosity flow activation energy and a relatively lowelasticity.

市场经济,社会存在和社会意识

本文在辨析马克思关于社会存在、社会意识和市民社会等基本概念的基础上,通过中、西现代社会发展史的比较,指出了国家、社会以及国家意识、社会意识在不同历史背景下形成过程的巨大差异。中国社会发展的独特性要求它在现代化的进程中进行一次国家与社会的剥离和国家意识与社会意识的剥离与整合。市场经济体制的改革为这次剥离提供了现实的可能性、必要性和迫切性。正统的国家意识随着中国改革的发展,已显示出蜕化为反社会意识的危     

拱的挠度理论分析

通过对拱的平衡微分方程受变形影响的研究,推导出抛物线无铰拱的挠度理论计算公式,并与弹性理论的计算结果比较,说明变形对大跨径拱桥的内力影响不可忽视。对于大跨径拱桥,弹性理论计算已不能正确反映拱结构真实受力情况,应按挠度理论分析计算。

Structural and expressional analysis of a cDNA that expresses predominantly in rice stamens

The development of stamen is an important stage during the sexual reproduction in higher plants. Studying the genes that predominantly or even specifically expressed in stamens will aid in undestanding the molecular mechanism of stamen development. The structure of a rice CHS-like gene (D5) which predominantly expressed in anthers has been analysised, showing high structural similarity with two other anther-specific genes (A1 and BA42) fromBrassica napus. Northern analysis also reveals that the three genes share a similar expression pattern and that the expression of D5 may relate to the early development of pollens. It is concluded that D5, A1 and BA42 represent a group of diverged CHS-like genes which are related to stamen development.
