| 4. | This attentional spike acts like a starting gun , after which the cortical cells resume their disorderly oscillations 由集中注意所引起的放电讯号,作用就像是信号枪,枪响之后,皮质细胞又回复了它们无规律的振荡。 |
| 5. | Exodermis an outermost layer of thickened or suberized cortical cells that sometimes replaces the epidermal layer in the older parts of roots if the epidermal cells have died 外皮层:薄的或木栓化的皮层细胞的最外层。如果根的较老部分表皮细胞死亡,它通常取而代之。 |
| 6. | The cortical oscillators connect to the striatum via millions of signal - carrying arms , so the striatal spiny neurons can eavesdrop on all those haphazard “ conversations . ” then something ? a yellow traffic light , say ? gets the cortical cells ' attention 这些皮质振?器经由上百万个传送讯息的手臂与纹状体连接,使得纹状体的棘神经元可以偷听到所有这些随意的交谈。 |
| 7. | The am fungus could obtain adequate carbon resources for itself , thus ensuring normal growth and metabolic activit y owing to the efflux of carbohydrate from the plasma membrane of the host root cortical cells to the interface of the symbiosis . thirdly , the structure and composition of the root cortex cellular plasma membrane kept good integrity and the leakage of carbohydrate maintained at low level when the plant obtained enough p and metabolizes normally . although enough carbohydrate was synthesized by plant , the am fungi could not obtain enough energy , resulting in inhibition of growth of the extraradical hyphae and decreased metabolic activity of the am fungi 由此,我们认为植物磷营养状况调控菌根真菌生长和代谢活性的机制是:当植物处于严重缺磷胁迫时,不能合成足够的碳水化合物供给自身生长的需要,也不能向真菌提供额外的碳水化合物,因而菌根真菌生长受阻,代谢活性较低;当植物中度缺磷时,根皮层细胞质膜的组成和结构不完整,通透性大,碳水化合物通过质膜向外的渗漏量大,菌根真菌因而获得充足的碳源,保证真菌正常的生长和旺盛的代谢;当植物获得足够的磷而使体内磷营养代谢正常时,其细胞质膜组成和结构完整,碳水化合物的渗漏量保持在较低的水平,尽管此时植物合成了足够的碳水化合物,但菌根真菌仍不能获得足够的能量,导致真菌生长受阻和代谢活性降低。 |
| 8. | 8 the pith made of small parenchyma cells was long - oval , however the pith looked like a cross which devided the preliminary xylem into four parts was made of larger parenchyma cells . 9 there are well - developed aerenchyma in suaeda salsa , including large sub - stomatal chambers and intercellular spaces in palisade layer , spaces produced by lysigenous breakdown of cortical cells in stem and roots 侣)髓在对照中仅由有限数目的较小的薄壁细胞构成,髓的形状表现为长椭圆形, 50 、 100 、 200 、 400inmnaci处理下,髓中的薄壁细胞较大,细胞数目较多,髓呈“十”字形,将初生木质部分割为四部分,这一特殊现象在前人的工作中尚未报道。 |
| 9. | 5 layer number of cortical cells in stem was n ' t changed evidently , however the ratio between cortical thickness and stem increased as well as the ratio between vascular cylinder and stem , up the gradient of nacl concentration . 6 stem dm of suaeda salsa remarkably decreased with increasing nacl concentration , so did the vessel dm of xylem in the stem ( 5 )随盐浓度的增加,茎皮层细胞层数未发生明显的变化,但皮层厚度所占茎的比重增加,维管组织占茎的比重同皮层厚度与茎半径的比值表现出相同的趋势。 |
