In this paper, a thermal simulation model of a LED driver was established. The thermal field and thermal stress analysis of the driver was done by using the software EFD Pro 8.2, and the temperature rise from various parts and the temperature field distribution of the PCB were obtained. By analyzing the reasons leading to overheating and unideal heat distribution, corresponding thermal simulation using an improved model was carried out. Finally, the comparison and analysis of experimental measurement results and simulation results were given.

In the respect of life ideal and aesthetic pursuit, Zong Baihua takes Goethe as his exemplar. His ideal of " artistic life" contains not only classic humanist standpoint, but also the moulage of Kantist super-utilitanrianism. On one hand, his ideal is full of moving creative spirit of Goethean lasting pursuit of life.

We then add boundaries delineated forward/backward facing reflected shock, Mechanical equilibrium, M2=1 and reflected shock strong/weak separating conditions on the (M0,q1) map of shih(2004). This is followed by systematically investigating multiply possible three shock theoretical solutions of steady Mach reflections in perfect triatomic gases. Pressure-deflection shock polar solutions are used to help illustrate different solution behaviors of these theoretical three-shock solutions. M0 is flow Mach no. upstream of incident shock, M1 is flow Mach no. downstream of incident shock, M2 is flow Mach no. downstream of reflected shock,q1 is flow deflection downstream of incident shock.
