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
