球形

Perianth subglobose, hemispheric, or urceolate, 5-parted or -lobed, slightly fleshy or herbaceous; segments abaxially thickened or becoming winglike or hornlike, rarely not modified, adaxially concave or cucullate.

花被近球形，半球形，或者瓶形，5深裂或者浅裂，稍肉质或草质；背面的裂片加厚的或变得翅状或角状，很少不修改，正面凹或兜状。

Microstrucfure of the powder samples achieved such as crystallographic structure, grain size, particle morphology, element analysis and thermal decomposition were characterized by means of X-ray diffraction, transmission electron microscopy, electron diffraction, energy dispersion X-ray spectroscopy and differential thermal analyzer etc.

结果表明，所制备的钠米镍粉、镍铜及镍铜硼复合粉呈颗粒均匀的球形或类球形，粒径在40nm～60nm之间。采用DTA方法对添加了纳米粉的高氯酸铵、AP／HTPB推进剂热分解情况进行表征。

In the dioxane/H2O system, spherical vesicles were obtained, and the size of these vesicles could be controlled by modulating the SBP concentration.

在二氧六环/水体系中，可以自组装得到球形囊泡，通过调节初始聚合物的浓度可以控制球形囊泡的尺寸。

The other cells of the tetrad undergo degeneration. The mature embryo sac consists of an egg apparatus, a central cell, and 3 antipodal cells. The embryo sac is a monosporic Polygonum type. The zygote develops into a mature embryo going through proembryo, globular, heart, and torpedo stages.

胚囊发育类型为单孢子蓼型胚囊； 2胚的发育经过原胚、球形胚、心形胚和鱼雷胚等阶段发育为成熟胚；胚柄在球形胚时期最发达，但胚柄短小，只由3个扁平细胞组成，之后逐渐退化。

The pollen of the samples is small pollen type, elliptic, long-spheric or subspheric,3-colporate,isopolar.

供试花粉均为小花粉类型，椭圆形、长球形或近球形，三孔沟，等极，表面有夹带二歧分叉的条状纹饰作纵向排列。

Drupes ovoid or globose; exocarp ± fleshy; endocarp hard. Seeds containing rich endosperm and tiny embryo.

核果的卵球形或球形；外果皮多少肉质；内果皮硬种子有丰富的胚乳和极小的胚。

Drupe ovoid or globose; exocarp fleshy or subdry; endocarp fragile; persistent style short, ca.

核果的卵球形或球形；外果皮肉质或者近干燥；内果皮脆；宿存花柱短，长约2毫米。

The results show that the pollen forms of Ferula and Heracleum are prolate and perprolate, respectively, and there are 3 colporates with reticulate sculpture on the pollen exines of the both genuses.

结果表明，阿魏属花粉形状为长球形，而独活属花粉为超长球形；2属花粉外壁均具有网状纹饰，3孔沟。

The interaction between concentrated CMC-Na solution and CB[6]could not induce the formation of gel bead.In concentrated CMC-Na solution,floccule was separated out from CMC-Na/CB[6]system and visible with naked eyes after placement.(4) CB[6]can complex with butyl ammonium hydrochloride to form stable pseudorotaxane(CB[6]/BA).

在CMC-Na/CB[6]配合体系中，CMC-Na与CB[6]聚集的纳米粒子形成较慢，需要经过放置才可以形成一些不太规整的球形纳米粒子；CMC-Na的浓溶液与CB[6]相互作用后，CB[6]对CMC-Na分子链的架桥作用要弱一些，在我们的实验条件下也没有象海藻酸钠浓溶液那样，形成球形凝胶粒子，将CMC-Na/CB[6]浓溶液配合体系在室温放置后，体系会出现许多絮状结构的聚集体。

Routine and analytical design methods for gas spherical gasholder are introduced, and their different features are discussed.

介绍了燃气球形储罐的常规设计和分析设计的设计方法，探讨了常规设计和分析设计的不同特点，介绍了我国燃气球形储罐采用分析设计法的实例。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
