长度、时间与我们的生活息息相关,是物理学中两个基本物理量,是学习物理学的基础.而长度和时间的测量又是物理学中最基本的测量,在物理学中有着重要的地位.在生活、生产与科研中,要能够正确使用常见的长度测量工具和时间测量工具测量长度和时间,还要能够根据测量的要求与实际情况正确选择长度和时间的测量工具与器材,以达到要求的测量精度.本文采阐述这一问题。
Length and time are closely related to our life, and are two basic physical quantities in physics, which are the basis for studying physics.Longness and time are the most basic measurements in physics and have an important position in physics. In life, production and research, to be able to correctly use the common length measuring tools and time measuring tools to measure the length and time, but also be able to correctly measure the length and time of measurement tools and equipment according to the measurement requirements and the actual situation in order to meet the requirements The measurement accuracy.This paper expounds this problem.
