求翻译：首先我们要对小波分析进行学习，学会利用小波分析进行电寿命预测的方法。然后对接触器了解其参数和工作环境要求。主要了解接触器的接触电阻和燃弧能量，测量并记录试验数据，利用所测数据建立小波和神经网络预测模型，经对模型的反复训练，得到电寿命预测模型。最后利用所建立的电寿命预测模型对接触器的电寿命进行预测，并将预测结果与实际相比较。是什么意思？

First of all, we would like to learn a small wave analysis, learn to use wavelet analysis of the electrical life prediction methods. And then the contactors for its parameters and the working environment. Learn about the main contactor contact resistance and fuel, energy, and measure and record test

First we must carry on the study to the wavelet analysis, the academic society carry on the electricity life forecast using the wavelet analysis the method.Then understands its parameter and the working conditions request to the contact device.Mainly understood the contact device the contact resista

First of all, we have to study on wavelet analysis, Institute prediction method using Wavelet analysis for life. Then contact their parameters and environmental requirements. Main about contact arcing and contact resistance for energy, measure and record test data, using Wavelet and neural network p
