做好电力建设工程安全设施"三同时"工作确保安全生产和工程长期安全稳定运行

我国现行安全生产法规要求电力建设项目的安全设施必须与主体工程同时设计、同时施工、同时投入生产和使用。电力建设项目应充分利用安全评价等现代安全管理模式,把安全设施“三同时”工作落到实处,确保从源头上建设本质安全型工程。为促进电力建设项目“三同时”工作健康有序发展,当前,各地和各有关企业要继续抓好落实企业安全生产主体责任、加大事故隐患整改力度、加强对建设项目“三同时”工作的监督指导,以及做好安全预评价和安全验收评价报告的评审备案工作。     

A Study of the Magnetic Properties of Intermetallic Compound RFe_(12-x)M_x

The structure and intrinsic magnetic properties of RFeM(M=V or Ti),type 1:12,have been studied bymagnetic measurement and X-ray diffraction.They are body-centered tetragonal ThMn_(12)structure.Thechanges of crystal lattice constants coincide with that of their element radii.Curie temperature is decided mainlyby the exchange interactions of 3d-3d and 3d-4f atom pairs.The data obtained by mean-field approximationagree well with experimental values.The magnetic moment coupling in these compounds for LRE isferromagnetic,and for HRE is antiferromagnetic.At low temperature,anisotropy field is decided by REsublattice.In this paper,the influence of magnetic properties of cobalt and nickel replacing iron has also beenstudied.     

16V240ZJ柴油机曲轴轴系的改进

本文论述了16V240ZJ柴油机改进后曲轴轴系的结构特点，研制过程中计算与实测结果的分析，对比，为保证柴油机可靠工作，作者从曲轴动态应力的实测结果出发，论述和评价了曲轴轴系的安全系数，指出该轴系不仅在平均有效压力为1600KPa时适用，进一步强化到平均有效压力为1900KPa时，仍能可靠工.
