根据国务院命令,我国计量单位一律采用法定计量单位,以便与先进国际单位制统一起来,并规定于1990年底完成过渡。我院广大科技人员都已在自己的工作中认真贯彻执行,在使用法定单位过程中也存在一些问题。例如,压强和模量,大家都已改用 Pa,1Pa=1N/m~2;质量用 kg;体积用 m~3;比强度和比模量的单位当然是 According to the orders of the State Council, all units of measurement in our country shall adopt statutory units of measurement in order to unify with the advanced international unit system and provide for the completion of the transition by the end of 1990. The vast majority of scientific and technical personnel in our hospital have conscientiously implemented their own work, and there are still some problems in the process of using legal units. For example, the pressure and modulus, we have switched to Pa, 1Pa = 1N / m ~ 2; mass with kg; volume with m ~ 3; specific strength and specific modulus of course
