【摘要】多分度秤是只有一個(gè)稱(chēng)量范圍，且該稱(chēng)量范圍又由不同分度值分成幾個(gè)局部稱(chēng)量范圍的一種秤，在對(duì)其進(jìn)行測(cè)量結(jié)果不確定度評(píng)定過(guò)程中需要確定檢定載荷點(diǎn)和分度值，測(cè)量結(jié)果的不確定度需滿(mǎn)足特定關(guān)系時(shí)，才可進(jìn)行相應(yīng)的符合性評(píng)定。
【關(guān)鍵詞】多分度秤；不確定度評(píng)定；載荷點(diǎn)；分度值

Abstract： A multi graduation scale is a type of scale that has only one weighing range and is divided into several local weighing ranges by different graduation values. In the process of evaluating the uncertainty of measurement results， it is necessary to determine the calibration load point and graduation value. When the uncertainty of measurement results meets a specific relationship， corresponding conformity evaluation can be conducted.
Key words： multi graduation scale； uncertainty assessment； load point； graduation value
0引言
多分度稱(chēng)作為一種數(shù)字指示秤，是一種分度值隨著稱(chēng)量的增大而自行變化的秤。（剩余2088字）
