无叶的

Shrubs or small trees, evergreen; new foliage shoots arising from subterminal buds and from axils of leaves; young shoots not scaly, glabrous or pubescent and glandular-setose.

灌木或小乔木，常绿；新的叶枝生于近顶生芽和叶的腋；幼枝无鳞片，无毛或被短柔毛和具腺。

"The photosynthetic and supportive cells tend to be organized linearly, but a thallus lacks such differentiated specialized structures as stem, leaves, and conducting tissue."

那些可进行光合作用和所维生的细胞呈线形结构，但原植体则无根、茎、叶的分化，无输导组织。

A leafless peduncle arising from ground level in acaulescent plants.

花葶 Scape 无茎植物从地表抽出的无叶花序梗。

Cauline leaves sessile, strongly auriculate or amplexicaul at base; leaf blade similar to that of basal leaves but with fewer lobes.

无柄的茎生叶，强烈耳形或者抱茎的在基部；除了具更少的裂片，类似于基生叶的的叶片。

Stipules absent. Leaves alternate, simple, odd-pinnate, or digitately trifoliolate; blades of simple leaves entire at margin, those of compound leaves crenulate, crenate, lobulate, or rarely entire at margin.

托叶无。叶互生，单，奇数羽状复叶，或者掌状具三小叶；单叶的叶片边缘全缘，复叶的边缘具细圆齿、圆齿，或具小裂片，或者很少边缘全缘。

Results The learning and memory ability of experimental group was better than that in saline control group (P＜0.01), but there was no significant difference between experimental group and normal control group (P＞0.05).There was significant difference in cytochrome C of hippocamp and frontal lobe between saline control group and the other groups (P＜0.01).The expression of cytochrome C in hippocamp was higher than that in frontal lobe of experimental groups.

结果 NSCs移植后AD模型大鼠的学习记忆能力明显改善，与生理盐水对照组相比差异显著（P＜0.01），与正常组相比无显著差异（P＞0.05）；海马与额叶的CytC表达显示生理盐水对照组与其他各组之间有显著差异（P＜0.01）；各实验组海马内的CytC表达均高于额叶。

PIV technique, a non-touch measurement method, was used as the experiment means. The unsteady flow within the vanelesss and vaned diffuser were measured and analyzed first time in our country.

实验中采用非接触式的PIV光学测量技术，在国内首次使用PIV技术对无叶扩压器、有叶扩压器两种结构形式扩压器内部的非定常流动进行了测量，分析了其中的流动特性。

Numerical calculation of the unsteady flow within turbomachinery The periodic unsteady flow within impeller/vaneless diffuser or impeller/vaned diffuser was numerical simulated in this thesis. The simulation was calculated on the CFX software flat.

离心风机内部非定常流动的数值模拟本文对叶轮/无叶扩压器和叶轮/有叶扩压器两种结构形式的离心风机内部流动进行了全流场非定常流动数值模拟。

Grayish woolly leafy perennial with branched stems ending in leafless stalks bearing golden-yellow flower heads; dry areas western North America.

多年生植物，叶浅灰色、有毛，花柄无叶，有金黄色的头状花序；长在北美西部干燥的地区。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
