交流量热技术已适用于高达 3 kbar 的静压气体压力。该方法的理论已扩展到考虑高气体密度和低样品热导率，并且所得方程已在因瓦合金和氯化铵样品上进行了测试。该方法对于研究在高压下经历二阶或更高阶相变的样品的热容变化特别有吸引力。
The ac calorimetry technique has been adapted for use at hydrostatic gas pressures up to 3 kilobar. The theory of this method has been extended to take into account high gas densities and low sample thermal conductivities, and the resulting equations have been tested on samples of Invar and ammonium chloride. The method is especially attractive for studying heat capacity variations in samples that undergo second‐ or higher order phase transitions at high pressures.
