  composites
In this paper, the so-called approximate convexity and concavity properties of generalized Gr?tzsch ring function μα(r) by studying the monotonicity, convexity or concavity of certain composites of μα(r) are obtained.
      
Preparation and properties of polymer and quantum dot composites
      
The prepared composites were characterized with UV-Vis, PL, TEM, FTIR, CLSM and conductance titration etc.
      
Spectra results indicated that there existed interactions between nanocarbon and the polymethyl methacrylate (PMMA) matrix, which was consistent with the decrease in glass transition temperature of the composites with increase of carbon content.
      
TEM images revealed that a carbon encapsulated core/shell structure was formed in the composites, which could ensure good dispersion of carbon nanoparticles within the PMMA matrix.

Sommaire Les etoiles Z Andromedae, T Coronae Borealis, AG Pegasi, BF Cygni, AX Persei, CI Cygni, R Aquarii et RY Scuti ont ete observers a l'Observatoire de Haute-Provence de 1946 e 1954. On donne une breve description de lews spectres qui sont tous composites mais avec des caracteres plus ou moins prononces. Des mesures spectrophotometriques ont conduit a Ia determination de leurs temperatures de couleur et de leurs temperatures electroniques.

The present paper proposes that the corrosion of glass fibres by hydrates of cementconsists of two aspects, namely, chemical corrosion and stress corrosion. The former lea-ds to the destruction of silica skeleton and the latter causes the extension of defects onthe fibre surface.The two effects Promoted each other will greatly lower or even comple-tely lose the tensile strength of glass fibres. Through the analysis. of research data and investigation on some experimentalstructures, the author holds that glass fibres coated with certain resinous materials willsimultaneously prevent chemical and stress corrosion of glass fibres by hydrates of cement,so as to make composites with ordinary glass fibres and cements.

本文提出了水泥水化产物对玻璃质纤维的侵蚀包括化学侵蚀与应力侵蚀二个方面,前者导致硅氧骨架的毁坏,后者引起纤维表面缺陷的扩展,二者相互作用从而使玻璃质纤维的抗拉强度大辐度地降低甚至完全丧失。根据对研究结果的分析与对试验性工程的调研,作者认为用某些树脂材料对玻璃纤维作被复处理,能同时阻止水泥水化物对纤维的化学侵蚀与应力侵蚀,因而有可能实现普通玻璃纤维与水泥的复合。

The effect of alloy element Zr on the Nb3Sn growth kinetics at the Cu-Sn/Nb interface has been investigated. Experiments have revealed that the addition of Zr in single core composites increases the growth rate substantially and the variation of the Nb3Sn layer thickness with reaction time obviously exceeds the parabolic law. These results cannot be interpreted fully taking into account the fineness of Nb3Sn grains caused by the ZrO2 particles formed during heat treatment, and it is necessary to consider...

The effect of alloy element Zr on the Nb3Sn growth kinetics at the Cu-Sn/Nb interface has been investigated. Experiments have revealed that the addition of Zr in single core composites increases the growth rate substantially and the variation of the Nb3Sn layer thickness with reaction time obviously exceeds the parabolic law. These results cannot be interpreted fully taking into account the fineness of Nb3Sn grains caused by the ZrO2 particles formed during heat treatment, and it is necessary to consider the increase of diffusion coefficient caused by supersaturation of vaeances around the ZrO2 particles. The depletion of Sn contents in the Cu-Sn matrix of multifilamentary composites during heat treatment greatly influenced the growth rate. The revised formula of growth kinetics gives a satisfactory explanation on the experimental results.

研究了合金元素Zr对Cu-Sn/Nb界面上Nb_3Sn生长动力学的影响。实验表明:在单芯复合材料中加入Zr显著提高了Nb_3Sn层的生长速率,层厚与时间的关系显著超过抛物线规律。这些结果不能仅用内氧化生成的ZrO_2颗粒使晶粒细化来解释,还必须考虑ZrO_2颗粒周围过饱和空位使扩散系数增大等因素。在多芯复合材料中热处理时Cu-Sn基体中Sn量的消耗,显著影响Nb_3Sn的生长。考虑了这一因素的Nb_3Sn生长动力学修正公式能对实验结果进行解释。
