营养盐海上现场测定数据质控初探

DATA QUALITY CONTROL IN SPOT DETERMINATION OF NUTRIENT SALTS AT SEA

营养盐现场测定,由于受海况、船只条件、水文状况、采水量及时间等诸多因素的制约,不可能进行多次反复的测定,因此数据的质量就显得尤基重要。本文拟就通过质控图的制作和应用,探讨营养盐测定中系统和人为误差的控制方法。

There many factors restricting the spot determination of nuti-ent salts on the sea.Usually impossible to repeat the operations for many times, it is necessary to set up a control method in the determination process. The article introduced a control system in the light of Quality Control Figure, which has been quite effective and verified by author's long experience at sea.
