Biological role of major transplantation antigens in T cell self-recognition

Summary The proposal is made, illustrated and supported by experimental evidence that T cell-mediated immunopathology triggered initially by low- or non-cytopathic infectious agents may cause diseases, susceptibility to which is linked to the major histocompatibility gene complex.This summary is an updated version of the paper given on the occasion of the Paul Ehrlich Prize ceremonies in 1983; it was also presented at the meeting New Trends in Allergy II in München 1985, and is reproduced here with the permission of Springer Verlag, Heidelberg.     

弯曲铝合金方管的轴压性能试验研究

为研究带初弯曲度铝合金方管的轴压承载力,完成了8个试件的轴压稳定性试验,并建立了与试验条件一致的有限元模型。通过对比试验和有限元分析结果验证了有限元模型的可靠性。结果表明,带有较大初弯曲度铝合金方管的破坏模式为整体弯曲失稳。最后,根据有限元分析结果拟合得到较大初弯曲度铝合金方管的整体稳定系数计算式,并将拟合计算式结果和数值分析结果及试验结果进行对比,验证了计算式的正确性。

Progress in magnetic couple system of nitroxidemetal complexes

Metal_radical method is an effective approach to synthesizing magnetic molecular materials. With the development in decades, the study of nitroxide_metal complexes has made great progress in model, theoretical treatment and design of molecules. Several mechanisms of the metal_radical magnetic coupling are discussed. Molecular magnetic project of nitroxide_metal complexes has made fruitful achievements, but crystal magnetic project is difficult to be controlled, and it is a challenge to chemists. The studies on nitronyl nitroxide_metal complexes are summarized. At present, there are three major approaches to increasing the T c of the metal_radical compounds: (ⅰ) Searching for nitronyl nitroxide ligands that can yield 3_D ferro_ or ferrimagnetic structures; (ⅱ) decorating the structure of radicals with the aim to enhance the coordinate capability of radicals; (ⅲ) grafting polynitroxide radicals as a versatile bridge. The third approach, namely searching for polynitroxide ligand, will serve as a hopeful strategy for exploring higher T c radical molecule_based magnets.
