In normal group and sham lesion group, BDA positive neurons were distributed symmetrically in the pyramid cells of sensorimotor cortex, and BDA positive fibers of pyramid cells passed through the cerebral cortex, internal capsule, cerebral peduncle of midbrain, basilar portion of pons to the pyramid of medulla oblongata. At the lower part of the medulla oblongata, most of the BDA positive fibers passed through the pyramidal decussation to the contralateral side, continously descended at the ventral part of posterior funiculus just dorsal to the posterior gray commissure and ended at sacral spinal segments.

正常组和假损伤组大鼠BDA示踪显示BDA标记阳性细胞定位于双侧感觉运动皮层的锥体细胞，锥体细胞发出的BDA阳性纤维束对称分布于双侧皮层、内囊、大脑脚、脑桥基底部、延髓锥体中的皮质脊髓束内，继而经锥体交叉到脊髓后索，在双侧后索最深层、灰质后连合背侧下行至脊髓骶段。

Mycorrhizal fungi enter the velamen and exodermis through root hair, invade the cortical tissue by the exodermal passage cells and then form pelotons.

独花兰具有典型的兰科植物菌根构造，在光学显微镜下可以观察到菌根真菌从根毛进入根被和外皮层，通过通道细胞侵入到皮层薄壁组织，在皮层薄壁细胞内形成菌丝团。

Root hair was not present on the roots of this plant. Root of D.candidum possesses the typical root structure of orchids including velamen, exodermis,thick cortical tissue, endodermis, pericycle, vascular bundle and pith. Strain AR-18grew toward D.

真菌AR-18倾向于根生长，真菌在根周围形成了一个包围圈，并侵入根被细胞，由根被继续侵入外皮层通道细胞，进一步向皮层细胞侵染，在皮层细胞内形成菌丝结，从而形成内生菌根。

The opioid receptors mainly distribute at prefrontal lobe(obitofrontal gyrus, medial superior frontal gyrus, superior frontal gyrus), paralimbic cortices (cingulated cortex and hippocampus), insular cortex、pallidum and the opercular section of frontal lobe and parietal lobe. These results corresponded with the classic theories on PET neurorecepotors imaging.

通过phfMRI方法进一步验证了人脑中枢系统内阿片受体的主要分布区，其中皮层区集中在前额叶(眶额皮质、额上回、额内上回)、边缘系统、颞叶脑岛区及额顶叶的岛盖部；皮层下区集中在苍白球区；小脑集中在小脑皮层、小脑脚及小脑蚓部。

The mechanisms underlying these biases of subcortical neurons are still under investigation.

视皮层内较强的方位、方向选择性主要是由视皮层内部机制形成的，而皮层下神经元也具有明显的方位、方向敏感性，并对视皮层神经元的方位、方向选择性有初步的贡献，然而这种皮层下方位、方向敏感性的形成机制仍在进一步的探索中。

There are two types of maturation according to our observation.One is nucleocapsids obtained its tegument in the nucleus and enveloped from the inner nuclear membrane.Another is nucleocapsids entered cytoplasm through nuclear membrane,then obtained their tegument in the cytoplasm,enveloped from the plasma membrane,finally released by necrosis,exocytosis or other ways.

病毒成熟有两种方式：一为细胞核内核衣壳在核内获得皮层，通过核内膜获得囊膜成为成熟病毒；二为核内核衣壳通过内外核膜进入胞浆，核内和胞浆内的核衣壳在细胞浆中获得皮层，然后在各种质膜上获得囊膜，最后成熟病毒通过细胞破裂或其他方式释放到细胞外。

Candidum root and surrounded it, and later penetrated the velamen cells.Or mycorrhizal fungus penetrated the exodermal passage cells through the velamencells and further infected the cells of cortex, and then formed pelotons in the corticalcells.

真菌AR-15由根被侵入外皮层通道细胞，在外皮层通道细胞内形成菌丝结，进一步向皮层细胞侵染，从而形成内生菌根，紧靠外皮层的皮层细胞具有多个细胞核和核仁，还发现细胞核正在进行穿壁运动。

The structure of the bladder was defined firstly to be 6 layers, tegument , exterior mesenchyma , parenchyma layer , interior mesenchyma , interior matrix zone and interior layer . The structure of the cervix was 3 layers, tegument , mesenchyma and Parenchyma .

首次明确了猪囊尾蚴的囊壁由外向内有皮层、外侧间质层、实质区、内侧间质区、内侧皮下基质区和内层6层结构；头颈部由外向内有皮层、间质层和实质区3层结构。

RESULTS: HIF-1α positively expressed at stratum neuroepitheliale retinae and purpurogenous membrane in the embryonic phase. Additionally, HIF-1α still positively expressed at stratum neuroepitheliale retinae and purpurogenous membrane, especially in ganglionic cells and inner plexiform layer, in early development.

结果：胚胎期视网膜神经上皮层及色素上皮层均有低氧诱导因子1α阳性表达，生后发育早期视网膜神经上皮层及色素上皮层也可见低氧诱导因子1α阳性表达，以神经节细胞、内网层更明显，随着发育进展，其阳性表达主要位于视网膜节细胞层。

The pattern of aerenchyma formation could originate by the combination of cortical cell autolysis and enlarged intercellular space. The process occurred in some stages: cortical cells stopped expansion and the intercellular space became larger at the initial stage. Cortical cells to collapse and autolysis were found with the disintegration of cell contents. After the evacuation of cell contents, cortical cells became shrinking and invaginated.

形成过程大体分为：皮层细胞生长停止，细胞间隙增大；皮层细胞衰老，并发生自溶，内含物解体；解体物逐渐撤走，皮层细胞开始收缩、内陷，当细胞内含物全部撤走，相邻细胞的残留细胞壁叠合即在两侧形成通气空腔；径向上相邻的皮层细胞逐步发生凹陷和细胞壁叠合，结合方形的细胞间隙一起构成通气组织。

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。
