在测量结果中 ,有效数字的正确使用 ,应引起检定人员的重视。确定用几位数字来表示测量的结果 ,是一个十分重要的问题。测量结果既然包含误差 ,说明它是一个近似数 ,其准确度有一定限度 ,在记录测量结果的数据位数时 ,应以测量所能达到的准确度为依据。如果认为不论测量结果如 In the measurement results, the correct use of effective figures should be caused by accreditation officers. Determining the number of measurements to represent the results is a very important issue. Since the measurement result contains an error, it indicates that it is an approximation, and its accuracy has a certain limit. When recording the data digits of measurement results, the accuracy of the measurement should be based on. If you think that regardless of the measurement results
