摘　　要：通过对比2种干燥方式,研究草酸钠干燥方式对N值标定的影响。对草酸钠的贮存方式进行了探讨,研究干燥后草酸钠在3种贮存条件下对N值测定的影响。研究了不同环境湿度对N值测定的影响,确定实验室环境的最佳湿度范围。进一步考证西北气候下草酸钠的最适宜干燥方式和贮存条件,从而保证N值标定的准确有效进行。The effect of the drying mode of sodium oxalate on the calibration of N value was investigated by comparing two drying modes.The storage mode of sodium oxalate was discussed to study the effect of dried sodium oxalate on the determination of N value under three storage conditions.The effects of different environmental humidity on the determination of N value were investigated,and the optimal humidity range for the laboratory environment was confirmed.The most suitable drying mode and storage conditions of sodium oxalate under the northwest climate were further investigated to ensure the accuracy and efficiency of N value calibration.
