将五六十年代提出的测定土壤有机碳矿化速率的密闭培养法用于测定土壤有机物质中12C及14C分解速率．为此，专门设计了一种吸收容量瓶．从而简化了实验室操作步骤．减少了14C的污染．
In the 1950s and 1960s, the closed culture method for determining the rate of soil organic carbon mineralization was used to determine the rate of 12C and 14C decomposition in soil organic matter. To this end, specially designed an absorption volumetric flask. This simplifies laboratory procedures. Reduced 14C pollution.
