控失尿素效果评价中分析方法之探讨

Inquiry into Analytical Method in Evaluation of Loss-Control Urea Results

介绍了一种新型肥料——控失尿素,并通过精密度、准确性等几个方面对3种尿素含量分析方法进行了方法学评价。从样品检测时间、检测成本、安全性等几个方面进行了探讨,最后确定了最适合控失尿素效果评价的分析方法。

A description is given of a new type of fertilizer, loss-control urea, and a methodological evaluation is done of three analytical methods for urea content with respect to precision and accuracy. These methods are investigated from the point of sample testing time, testing cost and safety, and finally the one is ascertained which is most appropriate for evaluating the effect of loss-control urea.
