确定了多元化合物 Pr_(2-x-y)R_xR_yF_(11.6)cO_2 Al_(0.4)B 的结构和磁性。用15at%左右的 co 和3at%左右的 Al 组合置换 Pr_2Fe_(14)B 中的 Fe,使磁体的居里温度 Tc 增加了近20%、各向异性场 h_A 增加了近30%。Tb 或 Dy 对 Pr 的部分置换,使 h_A 显著增加。但是,Nd 置换 Pr 却导致磁体在室温和77K 时各向异性场的明显降低。Tb 或Dy 的这种性质可归于 Tb、Dy 离子的较强的磁各向异性,而这种磁各向异性来源子强烈的晶体交互作用场。这些结果表明,Tb 和(或)Dy,co,Al 诸元素适当组合加入Pr-Fe-B 合金中,可大大改善磁体的磁性能。

本文所介绍的计算机模型基本上是属于热力学性质的。唯一用到动力学参数的地方是碳转化率与氧—碳比(O/c)之间的关系。它是衡量进料煤活性的尺度,可以取自实验数据,对未经试验的煤也可以在特定参数经验位的基础上加以估计。这个模型运... 详细信息

本文所介绍的计算机模型基本上是属于热力学性质的。唯一用到动力学参数的地方是碳转化率与氧—碳比(O/c)之间的关系。它是衡量进料煤活性的尺度,可以取自实验数据,对未经试验的煤也可以在特定参数经验位的基础上加以估计。这个模型运算可靠,本文还附有应用实例加以说明。

世界核心医学期刊文摘（眼科学分册） 2005年第11期1卷 29-30页

Background/aim: competing levels of cytokines, either locally within the eye o r systemically, may influence the eventual out-come of ocular inflammation. Pol ymorphism in the promoter part of the genes controlling cytokine production may result in either higher or lower production of the relevant cytokine to a given stimulus. The authors hypothesised that such polymorphisms may relate to visual outcome in patients with idiopathic intermediate uveitis. Methods: DNA was obtai ned from 125 patients with idiopathic intermediate uveitis and analysed for the interleukin 10 IL-10-1082G/Aand IL-10-819c/T, and interferon γIFNγ874T/A g ene polymorphisms. Associations with disease were calculated by both allelic fre quency and haplotype analysis, and associations between ocular disease outcomes and the presence of polymorphismswere identified. A bad outcome was defined as l oss of vision h eyes at 5 years from presentation when the e yes were quiet. Results: An initial screen showed that the 874T allele of the IF Nγgene was more prevalent in patients than controls (χ2=7.9; p=0.004 OR 1.7; 9 5%cI 1.2 to 2.6 (Pc=0.02), whereas the IL-10-1082/-819 AT haplotype of the i nterleukin 10 (IL-10) gene was not. Analysis of disease outcome showed an assoc iation between IL-10-1082 AA homozygosity and bad outcome (χ2 =13; p=0.0003). Moreover, the two cytokine polymorphisms taken together showed that up to 75%o f patients with a poor visual outcome had the combined IFNγ874TA or TT genotype together with the IL-10-1082AA genotype (χ2=13.2 p=0.0008 OR 6.4; 95%cI 1.8 5 to 23.6 Pc=0.1). conclusion: These results show that disease outcome in interm ediate uveitis may be partly determined by a complex interplay between cytokine genes and these results may have implications for future treatment with biologic al agents that target these cytokines.
