一、扭矩在力学计量中的重要性扭矩作为重要的力学特征参数之一,用以评估机械和动力设备的工作能力、能源消耗、寿命、效率和安全等性能,是机械产品开发研究、测试分析、质量检验、安全和优化控制等工作中不可缺少的内容。中国计量科学研究院分别于20世纪80年代初和90年代初建 First, the importance of torque in mechanical measurement torque as one of the important mechanical characteristics of parameters used to assess the mechanical and power equipment work ability, energy consumption, life expectancy, efficiency and safety and other performance is the mechanical product development, testing and analysis , Quality inspection, safety and optimization of control indispensable content. China Institute of Metrology respectively in the early 1980s and early 90s to build
