重复测定 meaning in English

duplicate determination
iterative determination

In order to analyze the differences of the content of ergosterol in the imazalil - sensitive and imazalil - resistant isolates of p . digitatum , the technology of hplc was used . the results showed that the contents of ergosterol between imazalil - sensitive and imazalil - resistant isolates were not significantly defferent ( p = 0 . 05 , dmrt ) when they grew in the medium without imazalil . interestingly , when imazalil ( 0 . 1 # g / ml ) was added to the medium , the content of the ergosterol in imazalil - resistant isolate ( pd07 ) was significantly higher than that in imazalil - sensitive isolate ( pd23 ) ( p = 0 . 05 , dmrt )
结果表明，在抗性菌株pd07不加抑霉唑的情况下， pd07和pd23中游离麦角甾醇的含量采用duncan ' s新复极差测验在5水平没有明显差异；但当pd07中加入0 . 1 g ml抑霉唑时，三次重复测定结果显示抗性菌株pd07中麦角甾醇的含量明显地要比敏感菌株pd23中的含量高，而且两者在5水平上差异显著。
