国务院于今年二月廿七日公布了《关于在我国统一实行法定计量单位的命令》。这一次的单位改革涉及几乎所有科学技术领域,机械工程中过去长期习惯使用的一些单位,如公斤力、吨力、工程大气压、卡、马力、托、标准大气压、高斯、奥新特等,都将逐步废除,而代之以新的国际通用单位。因此,在机械工程中的一些计算式、系数、手册中的曲线、常数都将有所变化,一些试验设备,如材料试验机、压力表、活塞式压力计等,也都要重新调整、改装。这些改革都应在近两、三年内完成,以适应机械工程发展的需要。为此,本刊约请全国量和单位标准化技术委员会委员兼秘书长、高级工程师李慎安同志在本刊分期介绍有关问题,从下期起,将计划继续刊登:“机械工程中的单位改革”、“量的单位换算”等。读者在这些方面有些什么意见、要求和问题,请及时与本刊编辑部联系。
The State Council promulgated the “Order on Uniform Implementation of Statutory Measurement Units in China” on February 27 this year. This time the unit reform involves almost all areas of science and technology, mechanical engineering in the past long-term customary use of some units, such as kg power, tonnage, engineering pressure, card, horsepower, care, standard pressure, Gauss, Gradually abolished, replaced by a new international unit. Therefore, some calculations in mechanical engineering, coefficients, curves and constants in the manual will change. Some test equipment, such as material testing machines, pressure gauges and piston pressure gauges, must be readjusted and refitted . These reforms should be completed in two or three years to meet the needs of the development of mechanical engineering. To this end, the magazine invited the national quantity and units of Standardization Technical Committee member and Secretary-General, Senior Engineer Comrade Li Shen in this issue to introduce the relevant issues, starting from the next issue, the plan will continue to publish: “Mechanical Engineering Unit Reform”, “quantity Unit conversion ”and so on. Readers in these areas what are some opinions, requirements and problems, please contact our editorial department.
