在理论分析和试验的基础上,找出了导弹推进剂红烟硝酸主含量四氧化二氮一直测量不准的原因;并据此提出了修改标定高锰酸钾标准溶液的方法——降低介质酸度,修改测定四氧化二氮含量的方法——建立试样量和高锰酸钾标准溶液用量之间的合理对应关系。
On the basis of the theoretical analysis and experiment, the reason why the main content of nitric oxide in the red smoke of missile was always inaccurate was found out. Based on this, the method of modifying the calibration solution of potassium permanganate - Acidity, Modification of the Method for Determination of Nitrous Oxide - A Rational Correspondence between the Volume of Sample and the Amount of Potassium Permanganate Standard Solution.
