本实验运用微波加热、压力消解。结果表明，在密闭容器内，对样品施加一定的微波能，大大加快了反应速度，提高了测定效率。样品不污染环境，也不被环境污染，与经典分析方法相对照，分析速度提高了数十倍，分析结果的置信度为９５％，没有显著性差异。该法具有操作简便、省时、省力，适合于大批量样品的测定及很好的推广普及价值。为土壤中有机碳含量的测定提供了一种准确、简捷的方法，亦可借鉴于其它样品的分析测定。
The experiment using microwave heating, pressure digestion. The results show that in a closed container, a certain amount of microwave energy is applied to the sample, which greatly accelerates the reaction speed and improves the measurement efficiency. The sample does not pollute the environment and is not polluted by the environment. Compared with the classical analysis method, the analysis speed is increased by several times, and the confidence of the analysis result is 95%, showing no significant difference. The method is simple, time-saving, labor-saving, suitable for the determination of large quantities of samples and good popularization of universal value. It provides an accurate and concise method for the determination of organic carbon in soils. It can also be used for the analysis of other samples.
