假设检验方法在产品研制中数据处理上的应用
|
摘要
针对试验或生产过程中测试方法、工艺、材料、配方等变更,如何评价产品性能是否受到影响的问题,本论文采用对比试验方法,以板材测试方法选择、涂层表面张力变化、玻璃化学增强用原料调整为例,运用假设检验中的秩和检验、t检验、F检验的方法,依次给出了母体分布情况不知及母体服从正态分布的情况下,评价某项指标测试数据均值、方差是否有显著差异,可为研制及生产过程技术状态管理、变更决策提供支持。
There are some changes about experiment and productive process, such as test method, process, and materials, ingredient, etc. How do we evaluate the performance of the product? How to take a conclusion about yes or no? The selection of sheet testing method, the change of surface tension of the coating and the adjustment of raw materials for ion-exchange glass are taken as an example. The article used comparative experiments with the help of hypothesis test, which are rank test, and t test and F test, to evaluate significant difference of the mean value and variance, whether the parent distribution is not known or obeys the normal distribution. It can provide support for decision of configuration change.
