Fruit usually a capsule, with pericarp crustaceous, scarious, or papery, dehiscing by teeth or valves 1 or 2 × as many as styles, rarely berrylike with irregular dehiscence or an achene.

果通常蒴果，果皮壳质、干膜质或者纸质，通过齿或者1-2个裂爿开裂，很少浆果状不规则开裂或者为瘦果。

Seeds small, obovate, angular and wingless or planoconvex with a narrow marginal wing; testa crustaceous, shiny; embryo small, straight; cotyledons subrounded, clasping, embedded in copious fleshy endosperm.

种子小，倒卵形，具角和无翼的或平凸具一个狭窄的边缘的翅；种皮壳质，发亮；胚小，直；子叶近圆形，抱茎，嵌入大量肉质胚乳中。

Drupe obliquely obovoid, with persistent calyx; exocarp thinly crustaceous; mesocarp thin; endocarp outside reticulate polygonous concave.

核果间接倒卵球形，具宿存的花萼；外果皮薄壳质；中果皮薄；内果皮外边网状多角的凹。

Seeds usually 3-angled; testa thin, crustaceous, smooth to reticulate or verruculose, sometimes adaxially invaginated at hilum; endosperm copious; embryo straight to distinctly curved, lacking chlorophyll; cotyledons broader and much longer than radical.

Spikelets pale yellowish, ovate to suborbicular, 1.5–1.8 mm, abruptly acute; upper glume hyaline, 2-veined with the veins marginal, ciliate along margins with long silky hairs; lower lemma similar but not ciliate; upper lemma pallid at maturity, ovate, as long as spikelet, crustaceous, obscurely striate.

浅淡黄的小穗，卵形到近圆形，1.5-1.8毫米，突然锐尖；透明的上面颖片，2脉具脉边缘，具缘毛沿边缘具长绢状毛；更低的外稃相似的但是不具缘毛；灰白色的上面外稃成熟时，卵形，倍于小穗，壳质，具条纹的不明显。

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。
