七、测量的器具在第一章里,我们曾叙述了测量的定义:测量就是将待测的量和另一作为标准的、与待测的量有相同类别,且大小为已知的量相比较,从而确定出待测量大小的一种实验操作。在第三章中,我们对如何取得物质世界里存在的各种各样的量作出了这样的肯定:它们必须通过使用测量器具并进行测量以后才能得到。即测量器具是取得待测量量值的根本手段。
Seven, measuring instruments In the first chapter, we have described the definition of measurement: measurement is the amount to be measured and the other as a standard, with the same amount of the amount to be measured, and the size of the known amount of phase Compared to determine the size of the test to be measured an experimental operation. In chapter three we affirm how to obtain the various quantities that exist in the physical world: they must be obtained by the use of measuring instruments and their measurement. Measuring instruments that is measured to obtain the value of the fundamental means.
