碳酸钙分解压力测定是多年来一直开设的物理化学实验。但效果常常不太理想。笔者近几年经过反复试验、分析和研究,对测温、测压、计算等装置和方法进行了改进,取得了较好的效果。现给以简要归纳和总结。 Calcium carbonate decomposition pressure measurement has been set up over the years of physical chemistry experiments. But the effect is often less than ideal. In recent years, after repeated experiments, analysis and research, the author made improvements to the devices and methods for temperature measurement, manometry, and calculation, and achieved good results. Now give a brief summary and summary.
