Abstract：Fortheselectionof experimentalparametersformeasuringtheoxygenandnitrogencontent intitanium-ironalloy bypulse melting-infraredabsorptionandthermal conductivitydetection method，astandardcurve was established byalloy steel，the instrument analysis power was set to 5.5kW ，and the sample weighing was between 0.03 and O.05 g，and it was wrappedinatincapsuleandstuffedintoanickelbasket，andtheoxygenandnitrogeninthesamplewerecompletelyreleased underthe jointactionof tin-nickeltwofluxes.The accuracyof theoxygenandnitrogencontent wasverified withtheexisting low-contenttitaniumaloystandard，andtheresultswereaccurate，andthemeasurementabilityofthe methodwas evaluated byMeasurement System Analysis （MSA）， which can meet the daily analysis requirements.
