| 释义 | > as lemmasice point ice point n. Physics the temperature at which ice is in equilibrium with water at standard atmospheric pressure (i.e. the freezing or melting point under these conditions).Formerly used as a fixed point (0°) on the Celsius scale, the ice point has now been replaced for this purpose by the triple point of water.

R. Hassler Compar. Weights & Meas. 9 I have always preferred the comparisons at the same temperature, and selected for it the melting ice point, (32° Fahr.) which is in itself a fixed point of the thermometer. 1903 Philos. Trans. (Royal Soc.) A. 200 108 The coefficient for hydrogen, at a pressure of 100 millims. of mercury at the ice-point, is given..as 0·00366254. 1941 Temperature (Amer. Inst. Physics) i. 10 A limitation of this scale [sc. Kelvin's thermodynamic scale] is that if we make the fundamental interval from the ice point to the steam point 100 degrees, the actual temperature of the ice point is subject to experimental determination. 2001 J. V. Nicholas & D. R. White Traceable Temperatures (ed. 2) iii. 102 The ice point can be used as a ‘poor man's triple point’ to achieve uncertainties of the order of ±2 mK. < as lemmas |
