Methods for test and factor analysis of system simulation results are presented in this paper. With small sample of experiment results, the methods can not only effectively solve the problem of correctness and creditability of simulation results, but also analyze the effects of each factor and their interaction. In this way, the methods can guide the modeling and modification of simulation system.

A high efficiency, linear, adaptive radio frequency (RF) power amplifier (PA) is presented. The working frequency is about 900MHz. The circuit employs a self-bias cascode for a higher performance and an adaptive bias to enhance linear and efficiency of the PA as well. This power amplifier is designed with the SMIC 0.18um CMOS RF process. The power supply is 1.8V. The simulation results show that the PA has a power gain of 30dB. In addition, the Power-Added Efficiency is over 33%.

In order to deal with the defects of the poor convergences and easily immerging in partial minimum frequently, a new algorithm is proposed based on the combination of genetic algorithm and BP neural network, which is called GA- BP algorithm. This algorithm is applied to optimization of initial weights of BP Network, the structure and learn rule. It searches through the total solution space and can find the optimal solution globally over a domain. In this paper, GA- BP algorithm is applied to the production practice of molecular distillation to purify essential oils in schisandra chinensis. The result shows that this algorithm greatly increases convergent speed and convergence accuracy comparing with the simplex BP algorithm, and could achieve better results.

Car seats are important component to the interior acoustic field, their existence and sound absorbing performance could affect the acoustic field significantly. A light bus was selected as the research object in this paper, the effect of seats to the interior acoustic filed was analyzed contrastively. In addition, based on the practical situation of car design, the acoustic models without seats, with seats neglected their sound absorption, and with seats considered their sound absorption in the passenger compartment cavity were established. Based on these models, the acoustic mode in the passenger compartment was computed, and acoustic-structural coupling analysis was conducted, the impact of seats on the interior acoustic field was analyzed.
