简介:对C12-35/10型发电组出力提高15MW可行性进行了技术分析并提出了相关的改造方案.
简介:ThestructureandintrinsicmagneticpropertiesofRFeM(M=VorTi),type1:12,havebeenstudiedbymagneticmeasurementandX-raydiffraction.Theyarebody-centeredtetragonalThMn12structure.Thechangesofcrystallatticeconstantscoincidewiththatoftheirelementradii.Curietemperatureisdecidedmainlybytheexchangeinteractionsof3d-3dand3d-4fatompairs.Thedataobtainedbymean-fieldapproximationagreewellwithexperimentalvalues.ThemagneticmomentcouplinginthesecompoundsforLREisferromagnetic,andforHREisantiferromagnetic.Atlowtemperature,anisotropyfieldisdecidedbyREsublattice.Inthispaper,theinfluenceofmagneticpropertiesofcobaltandnickelreplacingironhasalsobeenstudied.
