相对论中的测量研究

The Research on Measurement in Relativity

光速是相对论中的一个重要问题,相对论中的一个基本原理是光速不变,用光信号作为测量手段导致了相对论的时空有许多新的特性,如同时性的相对性、时间延缓、空间弯曲等。可以说,相对论的时空是由于对光信号的测量而建立的,相对论是一种测量理论。

Velocity of light is an important problem in relativity in which a basic principle is its being invariant. The light as a means of measurement leads to many new characteristics of time and space in relativity, such as the relative nature of simultaneity, time delay, space bend, and so on. So time and space in relativity are based on the measurement of light signals. Relativity is a kind of measuring theory.
