Abstract

Published elastic constant data for H2O ice in the Ih phase are compiled and evaluated. Fits of the five elastic constants for 50 ≤ T/K ≤ 273 are conducted to yield a reliable and convenient source for elastic constant values. Various elastic properties can be calculated from the elastic constants obtained herein. The elastic constants are used to determine the adiabatic bulk modulus BS for the same temperature range with an estimated uncertainty of less than 1.3%. Fitting those data yields an equation for BS that is extrapolated to provide values for 0 ≤ T/K < 50. The adiabatic compressibility KS, isothermal bulk modulus BT, and isothermal compressibility KT are calculated from BS. Comparisons are made to published data.Published elastic constant data for H2O ice in the Ih phase are compiled and evaluated. Fits of the five elastic constants for 50 ≤ T/K ≤ 273 are conducted to yield a reliable and convenient source for elastic constant values. Various elastic properties can be calculated from the elastic constants obtained herein. The elastic constants are used to determine the adiabatic bulk modulus BS for the same temperature range with an estimated uncertainty of less than 1.3%. Fitting those data yields an equation for BS that is extrapolated to provide values for 0 ≤ T/K < 50. The adiabatic compressibility KS, isothermal bulk modulus BT, and isothermal compressibility KT are calculated from BS. Comparisons are made to published data.

50 K–273 K温度范围内H2O冰Ih的弹性常数、体积模量和压缩性

对已发表的Ih相水冰弹性常数数据进行了整理和评价。对50≤T/K≤273时的五个弹性常数进行了拟合，得到了一个可靠、方便的弹性常数值来源。从这里得到的弹性常数可以计算出各种弹性特性。用弹性常数来确定相同温度范围内的绝热体模量BS，估计不确定度小于1.3%。拟合这些数据可得到BS的方程，该方程外推可提供0≤T/K < 50的值。绝热压缩率KS、等温体积模量BT和等温压缩率KT由BS计算。与已发表的数据进行比较。对已发表的Ih相水冰弹性常数数据进行了整理和评价。对50≤T/K≤273时的五个弹性常数进行了拟合，得到了一个可靠、方便的弹性常数值来源。从这里得到的弹性常数可以计算出各种弹性特性。用弹性常数来确定相同温度范围内的绝热体模量BS，估计不确定度小于1.3%。拟合这些数据可得到BS的方程，该方程外推可提供0≤T/K < 50的值。绝热压缩率KS、等温体积模量BT和等温压缩率KT由BS计算。与已发表的数据进行比较。

期刊介绍： The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
