一、第十期答案 1.答:溯源性是测量结果的一种特性,它使人们可以通过连续的比较链,将测量结果与适当的标准器(通常是国际标准器或国家标准器)联系起来。具有溯源性的测量是量值统一的保证。量值传递是量值溯源的逆过程。量值传递的方式有:通过基准、标准器进行逐级检定;通过传递标准器进行巡回检定;通过无线电台、电视台或卫星发播标准时间频率信号;发放标准物质和公布标准数据等。
A, Tenth Answer 1. A: Traceability is a measure of the characteristics of the results, which allows people to compare the chain through a continuous, the measurement results and the appropriate standard device (usually the international standard or national standard) contact stand up. Traceability measurement is the unity of the value of the guarantee. Volume transfer is the reverse of the trace of the quantity. Means of value delivery are: level by level through the benchmark, the standard test; pass the transfer standard test circuit; by radio, television or satellite broadcast standard time and frequency signals; release of standard substances and publication of standard data.
