摘要：
As pre-processing methods, both eliminating polynomial trend and five points three times smooth are used to analyze the vibration signal which sampling from an experiment. The original signal's curve smoothness and high-low-frequency are compared with those processed using of each method. The result shows that the five point three times smooth pre-processing method is effective in denosing precision bearing vibration signal while eliminating polynomial trend method is useless.
