| 摘 要： | 采用HH—S型数显恒温油浴锅和简易油浴锅对国家标准土壤样品进行样品消解对比试验。结果显示：两种样品前处理方法的测定结果，经t检验无显著差异；HH—S型数显恒温油浴锅消解进行样品前处理时，应把预先加热温度提高为195～200℃，消解温度提高为185～190℃，消解时间要严格控制在5min。

| Abstract: | The comparative test was conducted to determine organic matter of national standard soil sample by simple oil bath pot and HH - S type homoiothermal oil bath pot with displayed number. The results showed that the results from two methods were no obvious difference by t -test. The temperature should raise to 195 to 200℃ in advance when using HH -S type homoiothermal oil bath pot, and the digestion temperature is 185 to 190℃ keeping within 5 minutes＇ digestion time. |
