海水中五种化学要素即PO_4一P,sio_3一si,NH_3一N,NO_2一N,NO_3一N,是海洋浮游生物繁殖的营养料。如何准确测定海水中营养盐含量的时间空间分布情况,标准工作曲线制定,是测定工作中十分关键的一环。目前,各调查队.海洋研究所等单位大部分已陆续开展对海水中五项营养盐进行测定的工作。因此,在制定标准工作曲线过程中,要求认真、仔细地做好各个环节的工作,尽量减少或避免出现不必要的人为误差。下面就谈谈制定工作曲线过程中应特别注意的一些问题,
The five chemical elements in seawater, namely PO 4 -P, SiO 3 -Si, NH 3 -N, NO 2 -N, NO 3 -N, are the nutrient materials for the propagation of marine plankton. How to accurately determine the time and space distribution of nutrients in seawater, standard working curve, is a key part of the determination. At present, most of the investigation teams, the Institute of Oceanography, and other units have successively carried out the work of measuring the five nutrients in seawater. Therefore, in the process of setting standard working curve, it is required to conscientiously and carefully do all aspects of work, to minimize or avoid unnecessary human error. Here to talk about the process of working out the curve should pay particular attention to some of the issues,
