摘　　要：通过对发表于2013—2014年被spinger数据库收录的33篇和2014年被中国知网收录的15篇含有SOD的文章进行分析后发现:这些文章中,尤其外文期刊的文章中,都使用U作为SOD活性的单位,而不是使用SI规定的kat。造成这种现象的原因,一是由于目前使用最广泛的测定SOD活性的化学方法,都是间接表达了SOD的活性,使用U作为SOD的单位更加方便;二是绝大部分研究者仅仅将SOD作为阐述其科学研究内容的一个生理指标,他们在意的是SOD相对活性而不是绝对活性,SOD无论使用何种单位对阐述作者研究的科学问题并无影响,所以研究者更喜欢使用更简洁的方式表示SOD的单位。因此,需要广大科学研究者和编辑共同努力,重新定义SOD单位和推广SI单位。An analysis of 33 papers included in springer database published from 2013 to 2014 and 15 articles in CNKI in 2014 containing SOD revealed that in these articles, especially the foreign articles, the activity unit of SOD is U, instead of kat as is regulated by SI. The reasons are as follows. First, at present the most widely used method of determination of SOD activity is the chemical method, which is an indirect expression of the activity of SOD. So it is more convenient to use U as a SOD unit. The second reason is that most researchers take SOD as a mere physiological index, and they only care about the relative activity of SOD rather than the absolute activity. The unit of SOD does not matter much when researchers deal with their scientific problems. Therefore, researchers prefer to use a simpler way to express the unit of SOD. Hence, scientific researchers and editors need join together to redefine and soread the unit of SOD.
