查询词典 companion

Compadre: a friend, companion, or close associate

。这种说法在美国西南部较常见。

There was lots of organelle, such as rib somes, mitochondria in companion cell during the mature stage of SE. Also the plasmodesmata appeared in cell wall between SE and CC.

在筛管成熟期间，伴胞的细胞质较浓，内含辜富的核糖核蛋白体、线粒体等细胞器，与筛管相连的细胞壁上具有胞间连丝。

Companion cell An elongated thinwalled cell cut off longitudinally from the same meristematic cell as the SIEVE ELEMENT with which it is closely associated.

伴胞：与筛管分子侧面相邻的一种细胞，和筛管间有密集胞间连丝，它与筛管是由分生组织的同一个母细胞不均等分裂发育而成。

Subcellular localization of ATPase activity in the flesh of developing apple fruit was carried outusing a lead phosphate precipitation technique via electron-microscope. The ultrastrcture of phloemand its surrounding cells was also observed. The results showed that ATPase activity wasdominantly localized on the plasma membranes of sieve element/companion cell complex.

应用铅沉淀的细胞化学方法，研究了发育过程中苹果果肉内卸载区(韧皮部及其周围薄壁细胞)ATP酶的亚细胞分布和变化，并且，作为补充，观察了韧皮部及其周围薄壁细胞的超微结构。

The results displayed the symplasmic isolation of sieve element/companion cell complex from the surrounding parenchyma cells, and suggest that the photoassimilate unloading from phloem follows an apoplasmic pathway and must be facilitated via the sugar transporters.

由此可见，苹果果实韧皮部组织同周围薄壁组织存在共质体隔离，同化物必须通过糖转运蛋白的介导从筛分子以跨越质膜的方式卸出到质外空间，然后再装载到周围薄壁细胞中。

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

Suddenly the schooner in front of me gave a violent yaw, turning, perhaps, through twenty degrees; and almost at the same moment one shout followed another from on board; I could hear feet pounding on the companion ladder; and I knew that the two drunkards had at last been interrupted in their quarrel and awakened to a sense of their disaster.

突然，我前面的大船猛地一歪，大约转了一个二十度的弯。几乎就在同时，从船上传来两次叫喊声，我听到了匆匆登上升降口梯子的脚步声。我知道两个醉鬼最终停止了那场搏斗，终于意识到灾难即将来临。

His friends in the aft-cabin, with the exception of the pale governess, laughed at his impatience: she sighed as she watched the young man, chafing at the slow hours, pushing away his untasted wine, flinging himself restlessly about upon the cabin sofa, rushing up and down the companion ladder, and staring at the waves.

他的头等舱里的朋友们，都嘲笑他的急不及待，只有脸色苍白的家庭女教师不在此列：她叹息着瞧那年轻人埋怨时间过得太慢，推开那没有喝过一口的醇酒，烦躁地把身体投在房舱沙发上，在升降口梯子上跑上跑下，凝视着滚滚波涛。

I want you to love me, and let me be your companion.

我需要你对爱我，和让我是你的朋友。

My wife is dead, and I have no companion.
