种子1-12，光滑或者偶尔有皱，具胚乳或无胚乳，有时具翅，翅膜质，基生，无假种皮或有假种皮，假种皮基生或完全包围种子，膜质、肉质，很少有粘液子叶平，叶状或者厚，合生，发芽时出土。2n = 8，12，14。

Macrocystis and Nereocystis and is distinguished by its heteromorphic ALTERNATION OF GENERATIONS in which a large sporophyte alternates with a microscopic gametophyte, and in which growth takes place in a special meristem region on the surface of the thallus.

在这类植物的生活史中，孢子体比配子体小。配子体是由叶状体表面特殊的分生组织区发育而来的。

Female flowers borne in axil of a leaflike bract in a cup formed by 2 connate bracts.

2合生的苞片形成的一个叶状的苞片在一杯的雌花生于腋。

Female flowers several, borne at base of a leaflike bract.

雌花数个，承担一叶状的苞片的在基部。

On the whole world, the late Carboniferous reefs are made of Chaetetes reefs in early and phylloid reefs in late.

从全球来看，晚石炭世的生物礁主要是早期的 Chaetetes 生物礁和晚期的叶状藻礁，几乎没有珊瑚礁。

Cladodes borne in clusters, rarely solitary, green, flat, 3-angled, or subterete.

叶状枝生于簇生，很少单生，绿色，平，具3角，或近圆柱状。

Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape. Beside those cells some ependymal cells appeared many folds on the top of surface. In 2h and 16h groups the observation results seemed no significant differences from the corresponding control groups.

实验组结果：与对照组相比，在6小时和8小时实验组中，可见成团的鹅卵石状室管细胞隆起于表面，微绒毛更为丰富，微绒毛根部可见到若干微细小孔，在SFO体部的一些室管膜细胞的胞膜完全破裂，胞质几乎荡然无存，仅剩胞核居于细胞的一侧，直径有5.7μm，呈分裂叶状；与这些细胞邻近的室管膜细胞表面最高处多呈现皱襞。2小时与16小时的实验组的观察结果与对照组相比未发现明显差异。

Inflorescences racemose, few-flowered; bracts leaflike.

花序总总状，花很少；苞片叶状。

This relatiely high malignancy rate was likely due to the exclusie inclusion of symptomatic patients and likely included the arious pathologic types of benign-looking malignant masses (eg, metaplastic carcinomas, papillary carcinomas, mucinous carcinomas, and malignant phyllodes tumors).

相对较高的恶性率可能是由于排除了有症状的病人，而包括了各种病理类型的看似良性的恶性肿块(如：化生性癌、乳头状癌、粘液癌和恶性叶状肿瘤)。

Asiatic shrub or small shrubby tree having showy bell-shaped rose or purple or white flowers and usually 3-lobed leaves; widely cultivated in temperate North America and Europe.

亚洲灌木或小的灌木树，有艳丽的铃铛状的玫瑰色或紫色或白色的花，通常是三叶状的叶子；广泛种植在北美和欧洲的温带地区。

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。
