| 中文摘要: |
| 在设备正常且忽略人为因素的前提下，通过收集某配方的氧化锌粉料称量数据，运用柏拉图方法筛选称量过程影响因子并对其进行Mann-Whitney检验和等方差检验分析，寻找氧化锌粉料称量过程能力的关键影响因子。结果表明：提前量和点动值是影响氧化锌粉料称量过程的关键影响因子；与提前量为0.1 kg时相比，提前量为0.3 kg时的氧化锌粉料称量样本分布概率的标准差（简称标准差）高56%，提前量为0.1 kg时氧化锌粉料称量过程更稳定；与点动值为0.5 s时相比，点动值为1.5 s时的标准差高10%，点动值为0.5 s时氧化锌粉料称量过程更稳定。 |
| 英文摘要: |
| Under the premise that the equipment was normal and human factors were ignored，by collecting the weighing data of zinc oxide powder in a certain formula，the Plato method was used to screen the weighing process influencing factors，and Mann-Whitney test and equal variance test were carried out to look for the key influencing factors of the zinc oxide powder weighing process capability.The results showed that，lead value and inching value were the key influencing factors in the zinc oxide powder weighing process.Compared with 0.1 kg lead value，the standard deviation of sample distribution probability in the weighing of zinc oxide powder（short for standard deviation） 0.3 kg lead value was higher by 56%，and the zinc oxide powder weighing process was more stable when the lead value was 0.1 kg.Compared with 0.5 s inching value，the standard deviation of 1.5 s inching value was higher by 10%，and the zinc oxide powder weighing process was more stable when the inching value was 0.5 s. |
