In this paper, the author sets up the dynamic model of the vibratory extracting-driving piling machine, and carries out the dynamic analysis, parameter calculation and Matlab's simulation for this model. Using the equation reciprocity law to carry out the calculation of soil parameter and simulation, and using the genetic algorithm to make optimization of the machine on the basis of the simulation, the author gets the optimum self-induced vibration frequencies of the machine changing with the depth of the pile and the optimization result of other parameters, thus reaching the conclusion that along with the increase of pile sinking depth, the optimum self-induced vibration frequency becomes bigger, and the vibration mass becomes smaller, hence deepening the knowledge of the dynamic performance of this system.

When the concentration of L-phenylalanine was 6 g/L,the optimum values of volume ratio of organic phase to aqueous phase,reaction temperature,pH value and liquid volume were 1∶1,30 ℃,4.0 and 20 mL/250 mL respectively. Under above optimum conditions,the content of 2-phenylethylalcohol reached 3.0 g/L 48 h later,which increased by about 50% than that in monophasic aqueous system.

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.

本文的主要贡献及创新之处是：首次从理论上探讨了基于最小均方误差准则的最优天线阵在CDMA系统中的多址干扰抑制性能及其参考信号的产生方法，证明了采用有用信号相应的扩频码作为参考信号与采用将解扩信息与扩频码进行重扩频后的信号作为参考信号来调节自适应天线的权值均可使权值收敛于同一最优解。

Energy requirement for drying could be reduced by a dryer with a heat recovery device. In order to analyze the optimum operation conditions, the effect of fan speed on the temperature, airflow distribution and effectiveness of the heat recovery device was investigated in the drying system. The optimum fan speed would be at maximum speed during initial heating stage and at lower speed during steady stage in order to improve the performance.
