METHOD FOR TEMPERATURE MEASUREMENT AND ANALYSIS OF COHERENT PROPERTIES OF SURFACE NANO-LAYER SUPERFLUID MELT PORTION OF BORIC ANHYDRIDE

摘要

FIELD: physics.;SUBSTANCE: invention relates to fundamental physics and can be used for study of thermophysical properties of superfluid quantum fluids. Platinum-platinum-rhodium thermocouples 1 and 2 are submerged into molten pure boric anhydride 5. Method includes measuring temperature of nanosized layer of superfluid portion of molten boric anhydride 5 on surface of hot junction 3 of thermocouples 1 and 2.;EFFECT: invention enables to obtain isothermal condition of surface layer of superfluid part of quantum fluid in presence of temperature gradient.;1 cl, 2 dwg
