量热测量的结果容易受到各种系统误差的影响。恒温微量和纳热量计对此类误差特别敏感，因为测量的热功率非常低。在本文中，这样的错误的发生和影响进行了讨论：校准误差，基线误差，蒸发/冷凝的问题，吸附，pV工作，气态反应物和不同种类的机械效果。给出了几个数值例子。
Results of calorimetric measurements are easily impaired by different kinds of systematic errors. Isothermal micro- and nanocalorimeters are particularly sensitive to such errors, as the measured thermal powers are very low. In this paper the occurrence and effects of such errors are discussed: calibration errors, baseline errors, problems with evaporation/condensation, sorption, pV-work, gaseous reactants and different kinds of mechanical effects. Several numerical examples are given.
