This paper analyzes the characteristics of the basic noises with the two parameters of kurtosis and entropy in ICA. In view of the disadvantages of the traditional reliability screening method of photoelectron coupled devices , a new time-domain analyzing method based on the independent component analysis (ICA) was proposed to analyze the noise signals. The characteristics of the basic noises were analyzed with the two parameters in the ICA -- kurtosis and entropy. 例2 Considerable research has gone into the formation of nanosized noble metals by ultrasonic irradiation of aqueous solution.
