花瓣宽椭圆形；退化雄蕊小丘状在先端；萼片长圆形忍受的茎生叶干的近中部 9 P。

The stem barks of Lagerstroemia calyculata Kurz were extracted with methanol and isolated with silica gel column chromatography.

副萼紫薇的茎皮经甲醇冷浸提取，依次用石油醚、乙酸乙酯和正丁醇萃取。

Objective the chemical constituents of the ethyl acetate extract of Lagerstroemia reginae Roxb, Lagerstroemia calyculata Kurz and Lagerstroemia floribunda Jack were studied in this research.

目的：本研究对大叶紫薇、副萼紫薇和多花紫薇乙酸乙酯萃取部分的化学成分进行研究。

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。
