The effect of temperature on the population growth of Brachionus calyciflorus from the Nanhu Lake was studied at 15, 25 and 35℃ by population accumulative culture. The rotifer was fed with Scenedesmus obliquus at a concentration of 5.0×10^5 cells/mL.

应用群体累积培养法，以浓度为5.0×l0^5 cells/mL的斜生栅藻为食物，研究了温度（15、25和35℃）对南湖水体萼花臂尾轮虫种群增长的影响。

Sepals obovate, 8-10 × ca. 7 mm, densely red-brown scaly, with glands at base.

Petals yellow or white, longer than sepals; blade obovate, deeply 2-fid.

Flowers pedicellate; sepals linear-lanceolate to lanceolate, shorter or longer than petals.

花有花梗；披针形萼片线形的到披针形，短比花瓣或更长。

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.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
