【摘要】 概括介绍液氦温区国际实用温标的发展情况,系统地给出温标T24,T29,T32,T37,TBS,T48,T55E,TL55,T58,T62,T68,T76以及目前正在采用的T90之间的转换关系,为此编写了计算机程序,可直接用于以上各温标间的数值转换。更多还原

【Abstract】 This paper briefly introduced the development and the definition of the international practical temperature scales over the liquid helium temperature region.The conversion relationship between all the helium vapor pressure temperature scales T₂₄,T₂₉,T₃₂,T₃₇,T_BS,T₄₈,T_55E,T_L55,T₅₈,T₆₂,T₆₈,T₇₆ and the current adopted T₉₀ were presented.A computer program was written to realize these conversions.It will be helpful to the researchers who concern in the low temperature work below 5.2 K.更多还原
