控制

Institute of Plant Protection, Anhui Academy of Agricultural Science, Hefei 230031, China Abstract: The control effect of propiconazole microcapsule to postharvest anthracnose of apple and their application techniques at 25℃ and 10℃ in storage were studied. The results showed that the difference between the control effect with spraying and soaking were significant, the control effect of fast release for propiconazole microcapsule was better than that of slow release. The control effect of fast release for propiconazole microcapsule was 100% at 25℃ in storage, and was 86.8% 10℃ in storage.

But,the drawbacks of Shewhart's control chart is that when the control chart shows abnormal,it cannot tell us what and where is the assignable cause,i.e.it cannot diagnose the abnormalityof the process.In 1982,Prof.Gongxu Zhang proposed the diagnosis theory with two kinds ofquality,solved the diagnosis problem of assignable cause,thus opened a new direction ofstatistical diagnosis theory and developed the theory of SPC into a new stage ofSPCD(Statistical Process Control and Diagnosis).The multi-operation and multi-index system exists everywhere,in general,nearly all theproduction lines of factories belong to this system.

但休哈特控制图的缺点是，当控制图显示异常时，它不能告知是何原因、何处发生了异常，即不能诊断。1982年，我国著名质量管理专家张公绪教授提出两种质量诊断理论，解决了对异常因素的诊断问题，开辟了统计诊断理论的新方向，将质量控制推向了一个新的发展阶段——统计过程控制与诊断阶段。
