问:分析天平的微分标牌分度,是否可以在化学分析工作中看成绝对量值来代替砝码使用?——王昆刚答:天平的感量,应当空秤与全量时相接近,也不可能作到全量感量和空秤感量一样大,一般在空秤时略小一些,但也有“倒感量”的情况,即空秤感量反大于全量感量。使用天平的时候,随着载重不同,感量也不同,如载重100克时,用100克的感量,载重200克时,用200克的感量。一般分析天平,用微分标牌读数的感量(一个分度值)
Question: Analytical balance differential signs indexing, chemical analysis can be regarded as an absolute measure to replace the weight to use? - Wang Kun Gang A: The scale of the amount of flu should be empty scales and the full amount of time close, it is impossible For the full amount of flu and empty scales feel the same amount of the general, when the empty scale is slightly smaller, but there are “down feeling” situation, that is, the amount of empty scale is greater than the amount of the sense of volume. When using the balance, with the different load, the amount of feeling is different, such as the load of 100 grams, with a sense of 100 grams, when carrying 200 grams, with 200 grams of flu. General analytical balance, with a differential sign reading the amount of flu (an index value)
