通过实验评估了计数法的重复性等性能指标。测试结果表明,该方法可满足过滤行业日常检测需要。比较分析了单计数器顺序采样测试与双计数器同时采样测试,认为后者更适合于过滤行业。
The performance index such as repeatability of counting method was evaluated through experiments. The test results show that this method can meet the daily inspection needs of the filtration industry. A comparative analysis of the single-counter sequential sampling test and dual-counter simultaneous sampling test, the latter is more suitable for the filtration industry.
