补充资料：温度的固定点（fixedpointsoftemperature）
温度的固定点（fixedpointsoftemperature）
一些纯物质的相变点，它的温度是不变的，可利用这个特性来作为固定的温度点。在低温下IPTS-68，EPT-76，ITS-90都规定了一些固定点，利用这些固定点再加上扦补公式就可以对温度计进行分度。在低温下的固定点有以下一些：
水三相点273.16K
……………………平衡氢三相点13.803K
氙三相点161.404K
……………………Nb超导转变点9.2880K
氪三相点115.776K
……………………Pb超导转变点7.1997K
氩三相点83.8058K
……………………In超导转变点3.4145K
氮三相点63.1504K
……………………Al超导转变点1.1810K
氧三相点54.3584K
……………………Zn超导转变点0.8500K
氖三相点24.5591K
……………………Cd超导转变点0.5200K
