摘　　要：水中微量尿素的分析方法为二乙酰基一肟比色法,此法标准曲线制作难度较高,一般相关系数仅为0.99,甚至0.9,一般实验室要求标准曲线相关系数至少达到0.999,通过大量实验,从实验用水、试剂,以及操作过程中找出了影响分析方法的因素,最终实现目标。The analytical method of micro-urea in water is diacetyl-oxime colorimetric method.The standard curve of this method is difficult to make, the general correlation coefficient is only 0.99 or even 0.9, and the correlation coefficient of the standard curve required by the general laboratory is at least 0.999.Through a large number of experiments, from the test of water, reagents, operation process to identify the factors that affect the analysis method, and ultimately achieve the goal.
