22、cases, the workers will be temporarily distracted due to other reasons did not get the correct capacitance, and cause the entire process from long time delay. We believe that this phenomenon is mainly caused by two reasons: (a) operation with mobile capacitance in short time, frequent alternation of

23、 1 iron and tin line, and 2 of the 1 capacitor capacitor used alternately. Workers are easily distracted. This can be done by redistributing the left hand taskThrough observation, we can see that the workers left and right hand I order allocation is not reasonable, the distribution by changing the l
