When the amount of air was very few, even if the temperature was higher, the degree of oxidation of hydroxyl group and of hydrolysis and rancidity of ester group of castor oil was also very few. 当空气量很少时,即使在较高温度下,蓖麻油羟基氧化、酯基水解酸败程度也很小。
The higher the temperature was and the more amount of air was, the bigger degree of oxidation of hydroxyl group and of hydrolysis and rancidity of ester group of castor oil was; 温度越高,空气量越多,蓖麻油羟基氧化、酯基水解酸败程度越大。
