作为ASHRAE研究项目527的一部分，溴化锂和水溶液的热容已在100℃至200℃和45%至65%LiBr（按质量计）的标称范围内进行测量。测量采用滴式量热计实施的经典“混合法”。根据以水为标准参考物质的试验，并考虑到溶液可与之进行比较的准确度，该程序的最终准确度估计为+/-1.2%。实际效果在一定程度上降低了精度，对于整个测量系列，数据的精度估计为+/-5%。结果数据在其他研究人员的三组测量值内非常一致，但与两组较旧的数据基本不一致。提出了一种多项式回归模型来表示实际计算中的数据。 关键词:性能，溴化锂，水，溶液，高温，比热，测量，准确度，量热计，计算引用:ASHRAE Trans。1992年，第98卷，第1部分，论文编号3556（RP-527），137-149，图11。，8个标签。，裁判。

As part of ASHRAE research project 527, the heat capacity of lithium bromide and water solutions has been measured over the nominal range of 100 deg C to 200 deg C and 45% to 65% LiBr by mass. The measurements were done by the classic "method of mixing" implemented with a drop calorimeter. From tests using water as a standard reference substance and allowing for the accuracy with which the solutions can be compared, the ultimate accuracy of this procedure is estimated to be +/- 1.2%. Practical effects degrade the accuracy somewhat, and for the entire series of measurements the accuracy of the data is estimated to be +/- 5%. The resulting data agree well within three sets of measurements by other investigators but disagree substantially with two older data sets. A polynominal regression model is presented to represent the data in practical calculations.KEYWORDS: properties, lithium bromide, water, solutions, high temperature, specific heat, measuring, accuracy, calorimeters, calculating
