补充资料:测量与测量结果
测量与测量结果
测量与测量结果测量是以确定某个量的值为目的的一整套运作。例如,用米尺量布以确定布的长度为多少米,用体温汁量体温以确定体温为多少摄氏度等。测量的根本意义在于,可以将不能直接计数的量,如物体的长度、体积(容量)、质量(重量)等,通过测量确定其为多少米、多少升、多少千克等,从而变得可以汁数。依测量对象的性质和预定测量要求的不同,测量可能是简单的,也可能是复杂的。简单的量布和复杂的珠穆朗玛峰海拔高度的测量,都是对长度这个量的测量。 测量结果指由测量所得到的被测之量的量值,而量值则由牧字乘以计量单位组成。不管测量进行得多么仔细,测量结果都只是被测之量的真实量值的一个近似值。因此,在完整表述测量结果时,应包括给出测量不确定度。此外,必要时还要给出一些附加说明,如是单次测量所得还是多次测量所得,系统误差是否已作修正,以及测量时影响量的取值范围等
