Detection of Variation Sources in a Serial Production System

Variation is the fundamental cause of poor quality.In order to reduce variation and seek quality improvement opportunities,it is important to understand how variation is added and transmitted across the processes of the manufacturing system.In this paper,we introduce a model for variation transmission and give the method of detecting variation sources in a series connection manufacturing processes.Finally,anexample of the application of this method is given.     

面鱼入馔菜肴美

如今，小吃入馔的菜品比较受食客的欢迎。广元小吃“番茄鸡蛋面鱼汤”，其汤鲜味美，面鱼软韧，深受食客的喜爱。笔者受此启发，创制了几款以面鱼入馔的菜品，效果不错，现把其制法介绍给大家。面鱼的制法原料：面粉５００克鸡蛋２个精盐适量制法：面粉纳盆，磕入鸡蛋，加入精盐，掺入适量清水，搅打成稀稠适度的面糊，再用１根竹筷，顺着盆边将面糊刮成约６厘米长、０．５厘米粗的条，直接将其下入沸水锅中煮熟，随后捞出沥干水分，即成“面鱼”。［注］为了节省烹制面鱼菜品的时间，可一次性制作较多的面鱼，其方法是：先将煮熟的面鱼投凉…     

用PSPICE分析Z域网络传输函数

本文介绍了一种利用PSPICE分析Z域网络传输函数的方法，利用该方法可方便、准确地求出Z域网络函数的频率特性，还可求出该函数在不同输入信号的响应。
