Comparison Methods, the difference between a known and an unknown quantity to zero, that is so a null can be indicated. Inherently, such methods have a greater precision than direct measurements; for example, by using a detector that has a resolution of a microvolt it is possible to compare in terms of microvolts two要素 发表于 2025-3-26 06:04:57
