A new numerical differentiation method with local opti- mum by data segmentation is proposed. The segmentation of data is based on the second derivatives computed by a Fourier devel- opment method. A filtering process is used to achieve acceptable segmentation. Numerical results are presented by using the data segmentation method, compared with the regularization method. For further investigation, the proposed algorithm is applied to the resistance capacitance （RC） networks identification problem, and improvements of the result are obtained by using this algorithm.

The influence of different degrees of high reverse-bias stress on high power light-emitting diodes (LEDs) was investigated based on the aging of LED devices under the stress of 85℃/85% RH. GaN-based blue LEDs were respectively tested by negative Human-Body-Mode (HBM) electronic static discharge (ESD) at -1000 V, -2000 V, -3000 V, -4000 V and -5000 V. The electrical performances and optical performances of samples were measured before and after ESD test. The LEDs stressed at -1000 V, -2000 V and -3000 V showed a soft breakdown due to the generation of defect inside the chip and LEDs stressed at -4000V and -5000V showed a thermal breakdown. The thermal breakdown made temperature rise rapidly and formed a melting channel, which caused the damage of the LED. Though the electrical performances and optical performances of LEDs stressed at -1000 V, -2000 V and -3000 V did not show conspicuous degradation, the damage induced by ESD affect the reliability of LEDs.

In this paper, the analysis of transient thermal resistance is carried out on the basis of the regularization smoothing method and the Fourier series expansion method. These two methods are used to smooth cooling curve under the hypothetical model, and their result of smoothing and derivation are contrasted to the move average smoothing method under the actual model measured by T3ster. From theoretical model analysis and actual measured data analysis and application, it can be seen that the methods proposed have good effect on the analysis of transient thermal resistance.
