Myriophyllum aquaticum Verdcourt is a commonly cultivated, and nearly naturalized, species in Taiwan, characterized as follows: plants dioecious (only female plants known in China); aerial leaves glaucous or light bluish green; all leaves whorled, never entire, pinnately divided with linear segments; bracteoles subulate with 1(or 2) lateral lobes.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
