Results By using optical microscope,the neurocytes of hippocampus in experimental group were observed to denaturalize,tumefy,destroy and disappear.And under electron microscope,the karyon was irregular,nucleoles deviated,chondriosome tumefied,crista collapsed,membrane was damaged,substance cavitated.Such changes were more evident with the increased paroxysm of epilepsy,the parameters between control group and operation group had no difference（P＞0.01）.But make a monofactorial variance analysis among cells' number,area,circumference and integral optical density in different groups,it showed that there were significant differences between optional two groups（P.01;at the same time,the more serious injury in hippocampus,the more powerful GFAP immunoreaction was.

结果： 实验组海马区光镜下可见神经细胞变性、肿胀、坏死及神经细胞脱失改变，电镜可见细胞核形态不规则、有切迹、核仁偏位、线粒体肿大、嵴断裂、膜破损和基质空化等改变，随癫痫发作次数增加上述改变越明显，对照组与手术对照组比较，各参数差异无显著性（P＞0.05），将不同组别大鼠细胞数、面积、周长、积分光密度分别作单因素方差分析，不同组别间均差异有显著性（P.01），同时观察到海马区GFAP免疫反应阳性的胶质细胞随海马损伤的加重而GFAP免疫反应增强。

A new method to reduce the contact resistance between metal current collector and graphite plate for PEMFC has been proposed.

Moreover, the curve of mixing energies△G_m at different surface compressure vs molar fraction of nervonic acid appeared a positive deviation comparing to the ideal mixing surplus energies△G_M~1 curve, which indicated a phase separation phenomena in the mixed monolayer.

此外，在不同表面压下的混合自由能ΔG_m对神经酸摩尔分数曲线与理想的混合过剩自由能ΔG_M~1曲线相比出现相似的正偏差，说明这种混合单分子膜出现了相分离现象。

Leaves opposite, decussate, rarely alternate or verticillate, simple, entire, usually connate at base; stipules scarious, bristly, or often absent.

单叶对生，交互对生，很少互生或者轮生，全缘，通常在基部合生；托叶干膜质，具刚毛，或者通常无。

The interaction of DAB and RB with SPM and the cells are exothermal and idiopathic, which contained the union of non-covalent bonds, such as electrostatic bond, hydrogen bond and van der Waals force. Moreover, most of DAB and RB were accumulated on the excellular membrane and walls, to hardly enter the cytoplasm.

结果表明， DAB， RB与SPM和细胞外膜有强烈的单分子层化学吸附，是自发的放热反应，主要通过电荷对吸引、氢键等非共价键结合在SPM和细胞外表面，且绝大部分DAB， RB积累、滞留在细胞膜壁上。

However, by taking advantage of the steric restriction offered by the three ethoxyl groups on the heads of the C8TES molecules, as well as the difference of the chemical activities between the OTS and C8TES molecules, it was possible to construct both the homogeneously and phase-separated mixed C8TES/OTS SAMs by means of the stepwise method.

但是利用C8TES分子头部三个乙氧基所形成的空间位阻以及C8TES和OTS分子之间反应活性的差异，采用分步法可以制备出混合均匀的均相和相分离(Phase-separated)的C8TES／OTS混合自组装单分子膜。

Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.

SARS-CoV属于巢状病毒目、冠状病毒科，为单正链RNA病毒，基因组全长约29.7kb，已知编码11种蛋白，其中包括4种结构蛋白，分别是刺突蛋白、包膜蛋白、小包膜蛋白和核蛋白或核壳体蛋白。S蛋白三聚体形成突起，伸出包膜表面。S蛋白是病毒的主要表面抗原成分，具有受体结合和膜融合活性，在组织嗜性、细胞融合和毒力等方面起重要作用。N蛋白与基因组RNA结合形成核衣壳。M蛋白和E蛋白是包膜形成所必需的成分。
