净化

Eichhornia crassipes solms not only could survive wider range of pH (5～12), furthermore it could make the pH towards neutral.

在净化萘水溶液的过程中，凤眼莲不仅能够适应较广的pH（5～12），且能随净化时间的延长使pH逐渐趋于中性。

Proper amounts of sodium chloride could improve removal efficiency for naphthalene by Eichhornia crassipes solms in aquatic solution.

溶液中适量的氯化钠可以提高凤眼莲对萘的净化效率，当盐分含量超过0.3％时，凤眼莲净化效率明显降低。

The environmental factors influencing remediation efficiency were considered. And the feasibility of utilization of Eichhornia crassipes solms as resource was also presented.

筛选出凤眼莲并以其为主要对象，研究了水生植物净化萘水溶液的吸附、吸收、降解等过程，以及萘对水生植物生理指标所产生的影响及机理，考察了影响水生植物净化效率的环境因素，并对凤眼莲资源化利用的可行性进行了初步探讨。

It was shown that, the flow pattern in the EMPT was more complex than that in traditional one, that is, in the column chamber, the short circuit flow from the outlet nozzle of the ladle was depressed by the rotating molten steel, and horizontal recurrent flow appeared in rectangular chamber, which prolonged the average staying time of the molten steel, then reduced the volume fraction of inactive area in EMPT.

结果显示，电磁净化中间包的流场比传统中间包的流场复杂：在圆形腔中，旋转运动抑制了大包水口至矩形腔的短路流，而在矩形腔中形成水平环流，从而延长钢液在中间包的平均停留时间，死区减小，电磁净化中间包的上述流场结构及传输行为对钢液中的非金属夹杂物去除非常有利。
