问:1.用一台经中国计量科学研究院标定过的亮度计做标准,另一亮度计与之比较,所得结果能否认为是量值传递?2.如果要建立光度计量室需要通过哪些部门认可?这些手续如何办理?3.国内光度计量的情况如何?(王竹君)答:1.计量工作中的量值传递是指通过检定,将国家基准所复现的计量单位量值逐级传递给各级标准,直至工作用计量器具。用级别较高的计量仪器作标准与级别较低的仪器比较,以校准其示值,只有符合计量检定工作的要求时,才能叫做量值传递,否则只能算作一
Q: 1. With a calibrated by the China Institute of Metrology brightness meter as a standard, the other brightness meter with the comparison, the results can be considered as the value of transmission? 2. If you want to establish the photometric measurement room which need to go through Department approval? How to handle these procedures? 3. How is the situation of domestic photometric measurement? (Wang Zhunjun) Answer: 1. The measurement of the value of the transfer is through the test, the national benchmark of the unit of measure to reproduce the value of step by step Passed to all levels of standard, until the work of measuring instruments. Higher level with the standard measuring instruments and lower level instruments to calibrate its indication, only meet the requirements of metrological verification work, can be called the value of the transfer, or can only be counted as one
