However, the conversion rate of glycerol produced from the first stage using cornstarch to 1,3-propanediol from the second stage was only 26.5 % in 31h and the final concentration of 1,3-propanediol was 13.4 g/L. The productivity of 0.43 g/ of the second stage was much lower than that of a two-stage-fermentation from glucose （1.65g/ L） or of single fermentation from saponified glycerol, which is

The plasma arc generator comprises cathode, two anodes and insulating strip between two anodes, first anode is cylindrical hollow sleeve, the cylinder cathode is placed in the centre of said sleeve, and an annular fluid channel is formed between both the lower portion of first anode is equipped with a hole as fluid outlet, and second anode is a circular plate with central hole, between two anodes there is an insulating strip, the diameter of central hole of second anode is less than the diameter of lower hole of first anode.

本发明是一种串式多级压缩等离子弧发生器，由阴极、两阳极及阳极之间的绝缘片组成，第一阳极为圆柱形空心套管，圆柱体阴极处于该套管中心，并在两者之间形成环状流体通道，第一阳极下部是一个供流体出口的横截面为圆的孔，第二阳极是中心开孔的圆形板，两阳极之间有绝缘片，第二阳极中心孔的直径小于第一阳极下部孔的直径。

In the second part of of this thesis, we firstly derivate the operation condition of intracavity SHG of dualwavelength laser from the rate equation, and then numerically calculate the relationship between the laser operation parpmeters and the pumping powers. And then we discuss two possible ways to get balancing outputs of the harmonic waves of the two wavelengths. By comparing the two ways, we find that the method by increasing the geometrical factor of 1079. 5nm SHG has the higher efficiency than the method by adding the additional loss of 1079. 5nm basic wave. Besides, the first method is easier to realize in experiment than the second method.

本论文第二部分从速率方程出发，通过求解速率方程的稳态解得到了Nd：YAP腔内倍频双波长激光的连续运转条件，数值计算得到了随泵浦功率变化的激光运转情况；计算、分析了通过增加主波长的倍频耦合几何因子和增加主波长的腔内损耗两种方法获得均衡的双波长倍频输出的运转情况，通过二者的比较，发现增加倍频耦合几何因子的方法比增加损耗的方法效率更高，而且在实验上更易于实现。
