(ΩΩ)0+ Dibaryon Productions in Central Au+Au Collisions at RHIC Energy(SNN)= 130 GeV

Based on the measured transverse mass spectra ofπr-, K-, and p at the RHIC energy s()NN = 130 GeV,di-omega productions from baryon-baryon reactions in hadronic matter are studied. Results about the (ΩΩ)0+ numbershow that the deeply bound state (ΩΩ)o+ can be observed at RHIC energies.

纳米晶软磁合金中的结构对技术磁性的影响——Ⅱ.磁弹耦合作用

对磁弹耦合在决定纳米晶软磁合金宏观磁性中的作用进行了探讨,高场磁化规律以及正电子湮没测量表明:对Fe_73.5Cu₁Nb₃Si_13.5B₉合金,准位错偶极子造成的应力场对畴壁的钉扎效应是造成纳米晶软磁合金矫顽力的重要原因;结构缺陷造成的应力场与磁致伸缩的耦合作用对纳米晶软磁性能有重要的影响.在结构各向异性和磁弹耦合能共同作用下可解释纳米晶合金表现出最佳软磁性能.

新试剂二溴氟基偶氮氟胂分光光度法快速测定热镀锌合金中微量铈

报道了新试剂DBF-FAsA的合成及其应用于测定锌合金中添加微量元素铈量的方法。在强酸性体系中铈与二溴氟基偶氮氟砷(DBF-FAsA)形成蓝紫色配合物,其最大吸收波长为624nm,表观摩尔吸光系数ε为1.20×105L·mol-1·cm-1,线性范围为0～1.0μg/mL。该法可用于锌合金或中间锌合金材料中微量铈的测定。     

论《水浒传》"义气"文化的意义

《水浒传》是对“义气”文化的最好诠释。小说生动地表现了“替天行道”是“义”的根据、“济困扶危”“仗义疏财”是我们民族“义气”的基本内容、发现并尊重人才是“义”的最高表现形式,而且“义”还是团结人教育人的力量。
