溴化银颗粒在水中浸湿热的量热测定

Caloric Determination of Wetting Heat of Silver Bromide Granules in Water

补偿式数字量热计可以直接测定微小热效应,为了证实过程,本文以溴化银颗粒为例(比表面=0.21m^2/g,BET吸附N_2法测定),直接测定了在水中的浸湿热,其结果与文献记载一般固体的浸湿热相符。

Supplementary Digital calorimeter can be used to determine micro-heat effects directly. In order to prove the process the bromide granules (ratio surface = 0.2 ImVg, determined by BET absorption N2) were served as an example to determine its wetting heat in water, whose results were identical with the wetting heat of common solid recorded in literatures.
