纤维形成的

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。

The interface between pure Mo and interphase is smooth cycle, and that between pure W and interphase is discontinue one. The boundaries between interphase and TiAl matrix in both composites are serrated in as-cast condition, and the serration disappeares and smooth interphase ring is formed after HIPing.

显微组织研究表明，TiAl/Mo及TiAl/W复合材料在铸态下界面层厚度不大，且大多在TiAl基体中形成和长大，靠近Mo纤维的界面为光滑的环状，靠近W纤维的界面为微观不连续界面，而双方的另一侧以锯齿状向TiAl基体延伸。

Connective tissue from the breast cells, elastic fibers composed of collagen fibers, surrounded by glands, and the formation of a strip of solid support, known as COOPER's suspensory ligament, the ligament running from the skin deep skin membrane.

The filament winding pattern of the composite tube, winding parameters and undulation degree are studied in this paper.

本文介绍纤维缠绕复合材料管件的图型形成过程，并研究了影响图型的参数及纤维波动程度的计算。

From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .

体表皮由外及里共分为角质层、透明层、颗粒层、棘细胞层、基底层，EGF可以通过透明层、颗粒层、棘细胞层深入肌肤基底层，加速基底层细胞增殖分化，将已经分化成熟的细胞逆分化成干细胞，当达到一定量时，便会形成&干细胞岛&，加速新细胞的生成，让衰老细胞快速角化、脱落，已断裂、变性的胶原纤维和弹性纤维得到修复，皮肤弹性增加，皱纹逐渐平复、消失。

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or were of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes, with micropapillae floating freely in spongy spaces and separated by fibrous septa.

光镜下特征性表现为肿瘤细胞呈桑椹状、微乳头状或小腺管样排列，癌巢与周围间质形成明显的空隙，微乳头缺乏纤维血管轴心，每个微乳头细胞团和周边的纤维组织均存在无细胞的间隙样结构；瘤细胞CerbB-2、CgA和EMA。

The possible neurotransmitters mediating VLF-EPSPs were excitatory amino acids and non-NMDA receptors were critically involved in these synaptic transmissions,for both VLF-EPSP and glutamate-induced response were similary and almost completely abolished by kynurenic acid and DNQX.

提示VLF中的下行纤维可能与MN的胞体或近端树突形成突触，而背根或腹根中传入纤维与MN的远端树突联系。

Incubated with cytochalisin B for 4 hours, F-actin bunddles disrupted, confluent ECs monolayer has a complete detachment from the coverslips. So, there is a suggestion that the F-actin in ECs is essential for endothelial adherence under shear stress.

Northcrn杂交结果表明外源性纤维连接蛋白有促进EC肌动蛋白表达的作用，结合F-actin染色及FN受体染色结果，本文认为用纤维连接蛋白作为细胞种植的促粘附物质有助于内皮细胞粘附结构的形成。

The nanometre powders symmetrical separate on the surface of fibre and form the composite material with larger surface and with very large adsorption capability.

这种纳米复合纤维中，纳米微粉较均匀的附在聚合物纤维表面，形成表面积很大的复合材料，具有很强的吸附能力。

The particle of composite platings develops from singleness paticle to muti-paticle, muti-fibre. It forms muti-function composition platings to satisfy industrial require.

复合镀层中的分散微粒也从单一微粒、纤维向多种微粒、多种纤维等方面发展，形成具有多种功能的复合镀层，以更好地满足工业发展的要求。
