目的探讨不同水温对器械除锈效果的影响.方法除锈前进行清洗消毒,选出锈迹程度相近器械360件,随机分成3组,每组120件,实验组将其放入水温60-80℃,对照组1放入水温30-40℃；对照组2放入常温.3组都按1：10比例配置除锈溶液；浸泡5-10min,用软毛刷将器械在溶液中刷洗.比较3组除锈方法器械清洗合格率.结果实验组清洗合格率为98%,对照组1清洗合格率为82%,对照组2清洗合格率为79%,实验组和对照组比较差异具有统计学意义(P>0.05).结论生锈器械在水温60-80℃,1：10除锈溶液中浸泡除锈效果更好.

Objective To discuss the influence that different temperatures of water have on rust-removing effect. Methods Clean and disinfect the mental instrument before removing rust, pick out 360 pieces of them, the rust-effect degree of which is similar, divide them into three groups randomly, 120 pieces per group. Group one ( for experiment) puts them in water at 60 to 80 centigrade, group one ( for contrast ) puts them in water at 30 to 40 centigrade, group two ( for contrast ) puts them in ordinary water. All of these three groups deploy the rust-removing solution at the rate 1:10, soak them 5 to 10 minutes, and use soft rushes to scrub the instrument in solution. Compare the cleaning pass rate of these three different rust-removing methods. Results The cleaning pass rate of group one ( for experiment) is 98%, while that of group one ( for contrast ) is 82%, and that of group two ( for contrast ) is 79%. The difference between these two groups has statistical significance( p>0.05). Conclusion It is better to remove the rust on mental instrument by using the solution deployed from pure water at 60 to 80 centigrade at the rate 1:10.
