Inflorescence a terminal or leaf-opposed spike, with 4, rarely 6 or 8, white, petal-like involucral bracts at base.

穗状花序顶生或者与叶对生，在基部有4个，很少6或者8个，白色，花瓣状的总苞片。

Leaves borne on persistent, peglike projections, flattened or ± rhombic in cross section; bracts rudimentary, included.

宿存的叶生于，钉状预测，扁平或多少在横断面上；苞片不发育，包括。

Leaves not borne on peglike projections, leaving slightly raised, elliptic scars, grooved adaxially; bracts distinctly exserted, 3-lobed at apex

叶并非生于钉状预测，留下稍突起，椭圆形痕，正面具槽；苞片清楚外露，3浅裂的在先端 5 Pseudotsuga 黄杉属

Inflorescences subcapitate, many flowered, subtended by 1 or 2 stem leaves; bracts lanceolate-linear, small.

花序近头状，多花的，通过1或2茎生叶被包着；苞片披针形线形，小。

Inflorescences axillary or at leafless node, racemes or sometimes umbels; 1 bract subtending each flower, usually scale-like.

有时在无叶的节点，总状花序或的花序腋生或伞形花序； 1苞片在每朵花下面，通常鳞片状。

Ultimate segments of leaves ovate to ovate-lanceolate; bracteoles linear, entire, often shorter than flowers.

叶的末回裂片卵形的到卵状披针形；小苞片线形，整个，经常是短于花。

Stems caespitose, branched or not; leaf blade linear-lanceolate or elliptic-lanceolate, 3-5 mm wide [in Nepal, leaves to 8 mm wide]; racemes terminal or axillary; bracts linear, persistent at flowering; inner sepals ovate-oblong to elliptic-oblong.

茎丛生，分枝与否；叶片线形披针形或椭圆形披针形，3-5毫米宽 [在尼泊尔，对8毫米宽的叶 ]；总状花序顶生或腋生；苞片线形，在花宿存；内部萼片卵状长圆形的到椭圆形长圆形。

Female inflorescence oblong-cylindric or oblong; lobes of bracts with apex not reflexed; leaves with 9-21 lateral veins on each side of midvein

雌花序长圆形圆筒状或长圆形；苞片具先端的裂片不反折；叶具9-21侧脉在中脉两边各 12 Betula delavayi 高山桦

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。
