一、我们对“观测精度”涵义的理解最近《海洋仪器》上讨论温盐观测精度的文章~([1][2][2]),提到“观测精度”“仪器精度”等概念。可是,对“观测精度”涵义的理解却因人而异。在这种情况下,讨论是很难进行下去的。因此若要讨论温盐观测精度,就必须首先讨论它的涵义,求得一致的理解,讨论才有共同的语言。下面谈谈我们对“观测精度”“仪器精度”涵义的理解。(一)观测精度关于“观测精度”的涵义,赫、任的文章~([1])指出:“任一时刻,任一空间位置上,各种水文气象要素都有一个客观真实值(一般简称‘真值’)。但是严格来讲,‘真值’是很难测
First, our understanding of the meaning of ”observation accuracy “ Recently the article ”[1] [2] [2] Precision “and other concepts. However, the understanding of the meaning of ”observation accuracy“ varies from person to person. In this case, the discussion is very difficult to go on. Therefore, if we want to discuss the precision of temperature and salt observation, we must first discuss its connotation, get a consistent understanding and discuss a common language. Let’s talk about our understanding of the meaning of ”observation precision “ ”instrument precision “. (1) Observational Accuracy As for the meaning of ”observation precision“, He, Ren’s article ~ ([1]) states: ”At any moment, any hydrological meteorological element has an objective reality Value (commonly referred to as ’truth’), but strictly speaking, ’truth’ is hard to measure
