萼

Flowers bisexual or unisexual, regular, hypogynous, solitary or in cymes or thyrses; bracteoles often inserted just beneath calyx and then not always easily distinguishable from sepals.

花两性或单性，整齐，下位，单生或组成聚伞花序或聚伞圆锥花序；小苞片通常着生在花萼正下方，小苞片于萼片不容易区分。

The purpose of this study is to compare the effects of sea temperature on growth rate and mortality of reef corals, Stylophora pistillata and Seriatopora hystrix.

中文摘要本论文比较不同温度对萼柱珊瑚和尖枝列孔珊瑚生长率及死亡率的影响。

The pattern of diurnal cycle also can be classified into three strategies:(1) Planulation of S. hystrix and S. pistillata revealed a well-defined diurnal pattern with most planulae being released close to sunrise.

在日夜周期方面也可分成三种生殖策略：(1)尖枝列孔珊瑚与萼柱珊瑚有明显的日夜周期，释放幼生周期的同步性高，而且释放时间集中在天亮前后。

Calyx teeth obsolete. Petals white, elliptic to oblong, apex acuminate, inflexed.

萼齿不明显花瓣白色，椭圆形到长圆形，先端渐尖，内折。

Calyx teeth obsolete. Petals white or pinkish, obovate, apex with narrow inflexed lobule.

萼齿不明显花瓣白色或者带粉红色，倒卵形，先端具狭窄的内折的小裂片。

Calyx teeth obsolete. Petals white, purple or greenish yellow, spatulate to obovate with a narrow inflexed apex.

Male flowers: calyx lobes 4, imbricate; stamens inflexed in bud; pistillode top-shaped.

雄花 萼裂片4，覆瓦状；雄蕊在芽中内折；退化雌蕊顶形成。

Calyx teeth obsolete. Petals yellow, obovate, mid rib conspicuous, apex with narrowly inflexed lobule.

萼齿不明显花瓣黄色，倒卵形，明显的棱中期，先端具狭内折的小裂片的。

Scapes 2 or 3, few flowered; involucral bract petiole 1--3 cm; bracteoles present, small; sepals puberulent.

花葶2或3，很少花；总苞片叶柄1 --3厘米；小苞片存在，小；萼片被微柔毛。

Involucral bracts 14-18 mm; calyx lobes 5-7 mm.

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。
