模拟试验主要模拟农田的基本情况，测定土壤淋溶液中氮的含量，采用半微量开氏法。
The simulated test mainly simulates the basic situation of the farmland, determines the content of nitrogen in soil drench solution, and adopts semi-micro Macro Kjeldahl method.
半微量定性分析法的实验废弃物数量虽少，但成分复杂、毒性大。
The experiment wastes in half minim qualitative analysis methods are not in great number, but their components are complex and of great toxicity.
应用KDY-9820凯氏定氮仪测定羊肉中挥发性盐基氮，通过与半微量定氮法对比及精密度实验，结果表明KDY-9820全自动定氮仪能简便、快速、准确地测定肉中的挥发性盐基氮。
