| 摘 要： | 棉纺工业生产的半成品、成品质量考核指标较多，并且数据处理的理论与方法不一致，不适应现代化质量管理的需要。本文拟采用变异系数CV（％）值统一考核与控制棉纺半成品、成品质量，作为尝试。 |
| 关 键 词： | 棉纺 变异系数 工程能力指数 样本标准差 半成品 成品 质量考核 |

| Abstract: | In checking quality of products in cotton spinning industries , many indices are required nowadays . There is lack of agreement in the procedure taken in data treatment with the theory concerned . This situation does not suit the requirement of modern quality control . A comprehensive method using coefficient of variation is suggested for controlling the quality of products , both finished and semifinished , in the cotton spinning industries. |
| Keywords: | cotton spinning coefficient of variation an index of engineering capacity sample mean-value samle standard deviation |
