The enthalpy of combustion of cholesterol was measured in an adiabatic, rotating-bomb calorimeter capable of high precision with relatively small samples. The random error for the experimental measurements was 0.006 percent which may be compared with approximately 0.3 percent for prior investigations on this substance. The results obtained for the enthalpy of combustion and the derived enthalpy of formation together with the estimated overall uncertainties are: The results of prior investigations are discussed briefly.
胆固醇的燃烧焓是在一个绝热、能够对相对少量样品进行高精度测量的旋转弹热量计中测定的。实验测量的随机误差为0.006%，相比之下，此前对该物质的研究误差约为0.3%。所获得的燃烧焓和推导的生成焓结果以及估计的总体不确定度如下：对先前研究的结果进行了简要讨论。
