Fresh weight, dry weight, root activity, peroxides activity and catalase activity were measured. The results showed that FW, DW, root activity, POD activity and CAT activity of Vallisneria natans L and Elodea nuttallii were improved when ammonia concentrations were less than 50mgkg^(-1) and 500mgkg^(-1), respectively.

试验结果表明，氨氮起始质量分数＜50mgkg^(-1)和＜500mgkg^(-1)时可以分别促进苦草和伊乐藻鲜物质量、干物质量和根系活力的增加，大于此范围则会抑制苦草为Vallisneria natans L和伊乐藻Elodea nuttallii的生长。

解方程的根是提高截球效率的关键，本文采用高效的弦割法来快速计算方程的根。

Aiming at the problem of the odd point in the calculation of rotors torsional vibration characteristics by using the improved Riccati method, this paper presents a new viewpoint about how to confirm and remove the lost root and the added root of equation.

本文针对采用改进型Riccati方法计算轴系扭振特性中所出现的奇点问题，提出还需检测判断剩余量与振型，从而进一步确定和排除方程"漏根"和"增根"的方法。

In this paper, a new method used to deal with the motion ability is studied deeply based on Routh-Hurwitz Criterion. The advantage of this kind of analysis method consists in the fact that after establishing the equation in differential calculus for the motion system, there is no need to know a root of the equation, if you know the root signs, you can judge the zero solution stability of the system.

本文利用劳斯－赫尔维茨判据(Routh-Hurwitz Criterion)对机械系统中离心转速调节器的运动德定性进行了分析，这种分析方法的优点就在于：建立系统运动微分方程的特征方程后，不必求解特征方程的根，只需知道根的符号就可判断系统的零解稳定性。
