摘要
将有限差分法与神经网络技术结合起来用于估算电子枪主透镜尺寸误差的存在对屏上电子束束斑的影响.与以往的计算方法相比,该方法可避免许多复杂计算,节省了计算时间.一旦网络训练完毕,在很短的时间内即可估算出电子枪主透镜尺寸误差对屏上电子束束斑的影响,对提高CRT的成品率很有帮助.
The infinite difference method is combined with the neural network technique. It is used to estimate the effects of the electron gun main lens dimension error to the electron beam spots on the screen. Compared with the normal calculation method, this method can save computation time, avoid much complex calculation and save many computer sources. Once the network is well trained, it can predict the effects of the electron gun main lens dimension error to the electron beam spots on the screen in a short time. This method is very useful to the CRT production.
