羽状

Any field guide will mention the carpal/greater covert bar of Bulwer's Petrel, which is often not visible at range.

任何图鉴都会提到穴鸟大覆羽上的条状纹路，在远距离下可能不容易看到。

Of animals that can fly some are furnished with feathered wings, as the eagle and the hawk; some are furnished with membranous wings, as the bee and the cockchafer; others are furnished with leathern wings, as the flying fox and the bat.

一些飞行动物装备有羽质翅膀，如鹰和隼；一些装备有膜状翅膀，象是蜜蜂和金龟子；一些装备有皮质翅膀，像是果蝠和蝙蝠。

Sori borne on the basal segments of the pinnules, indusium cylindrical, mouth hardly dilated and lobed; receptacle protruding, curved, dark brown.

孢子囊群生於小羽片的基部裂片上；囊群盖筒状，口部几不扩大和分裂；囊群托长而突出，弯曲，黑褐色。

All flying creatures possessed of blood have feathered wings or leathern wings; the bloodless creatures have membranous wings, as insects.

所有拥有血液的飞行动物都是羽质或皮质翅膀；无血的动物是膜状翅膀，像是昆虫。

Basal leaves petiolate, rosulate or not, lyrate, sinuate, dentate, or entire.

具叶柄，莲座状的基生叶与否，大头羽裂，具深波状，具牙齿，或全缘。

Basal leaves petiolate, rosulate, simple, entire, coarsely dentate, or lyrate, with persistent petioles.

具叶柄，莲座状，单，全缘的基生叶，粗牙齿，大头羽裂的或，具宿存的叶柄。

The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

例如，荫湿生环境下的羽枝青藓Brachythecium plumosum，其中肋细胞胞壁较薄，无导水主细胞和副细胞的分化，也没有厚壁细胞分化，能够在阴湿环境下吸收水分和养分；钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构，叶片较厚，中肋具导水主细胞，中肋背面具厚壁细胞，这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中；水灰藓Hygrohypnum luridum叶片纤细柔弱，仅1层细胞，细胞胞壁薄，叶表无附属结构，中肋细胞层数少，无导水主细胞分化，也没有厚壁细胞，这些特点使得水灰藓'能够生长在水生环境中；东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片，东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物，这些附属结构使它们能够适应于旱生的环境中。

But the feather color also has the very big change in the summer and the winter, summer the mouth is the orange yellow, the foot is the black, the foot is the yellow, the eye is a blue color first; The occiput is living has the spear shape long shape aigret which many tall and slender white feathers compose, the longest 2 be more than 10 centimeters, look like a pair of gentle braid, flutter in the wind, beautiful moving.

但羽色在夏季和冬季也有很大的变化，夏季嘴为橙黄色，脚为黑色，趾为黄色，眼先为蓝色；枕部着生有多枚细长白羽组成的矛状长形冠羽，最长的2枚长达10多厘米，像一对细柔的辫子，迎风飘扬，美丽动人。

A feather, wing, fin, or similar appendage.

羽、翼或鳍状结构羽、翼、鳍或类似的悬着物

A hairlike feather having few or no barbs,usually located between contour feather s.

纤羽具有少量或没有羽支的发状羽毛，通常处于外侧羽毛之间

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。
