The article introduces the thermal decomposition kinetics of potassium oxalate-hydrogen peroxide in nitrogen, using the programmed temperature method and NETZSCH STA409 PC/PG Comprehensive Thermal Analyzer, measures the sample's TG and DSC curves in the condition of different heating rates in nitrogen, and analyses the kinetics model of thermal decomposition by the multiple nonlinear regression.

利用程序升温法在NETZSCH STA409 PC/PG综合热分析仪上研究了草酸钾－过氧化氢在氮气氛围中的热分解动力学，测定了样品在氮气中不同升温速率下的TG和DSC曲线，采用多元非线性回归对其热分解动力学模型进行了筛选研究。

The results show that though the strain is growing slower in the nitrogen-free medium than in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium. The capsular polysaccharides produced by the strain in the culture which contains different mineral powders will reach the highest content on the third or the fourth day in its growing period. The strain's capability of releasing potassium from k-feldspar and biotite in the nitrogen-containing medium is higher than that in the nitrogen-free medium because in the nitrogen-free medium, the strain and its production of glucoprotein are less than those in the nitrogen-containing medium.

结果表明，尽管该菌在无氮培养条件下的菌体数量远小于有氮培养条件，但无氮培养条件下所提取的细菌多糖多于在有氮条件下培养所提取的细菌多糖；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的无氮培养基中生长可形成大量多糖，采用丙酮法进行细菌培养液多糖提取，发现细菌培养的第3天所提多糖含量最高；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的有氮培养基中生长亦可形成较多的多糖，且在细菌培养的第4天所提多糖含量最高；胶质芽孢杆菌在有氮条件下对含钾矿物的释钾率高于在无氮条件下的释钾率，这可能与该菌在有氮条件下生长更快、可产生较多菌体细胞有关。
