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。

We show here that the transmembrane protein semaphorin 5A (Sema5A) is a bifunctional guidance cue exerting both attractie and inhibitory effects on deeloping axons of the fasciculus retroflexus, a diencephalon fiber tract associated with limbic function.

这里我们观察到跨膜蛋白信号素5A（semaphorin 5A，Sema5A）是一种双功能的向导信号，在后屈束（伴随有缘的功能的一种间脑的纤维束）的轴突发育中起这吸引和抑制的作用。

The transverse elasto-plastic mechanical properties of fiber bundle reinforced composites were studied by using the micro-mechanical model and finite element method.

纤维束复合材料的主要力学特征就是纤维的接触效应。首先纤维互相接触而产生相互作用，这种相互作用对宏观性能有不同程度的影响。

This paper proposes that willow bushes are used to prepare plate,and introduces the experiment and results.Fiber reinforced technology is introduced into scriber's reinforcement.

纤维束定向板材(也称重组木Scrimber)是近30年来，国内外人造板研究发展的最新技术，它是利用横向不断裂、纵向连续的木束，经干燥、铺装、施胶和热压而成。

There were no significant different about the thickness of epidermis in ETE group and RTE group; The collagen fiber in ETE group is more tenuity and the distance between them were increased on the basis of RTE group showed; the I type collage content decreased distinctly.

结果： 极限扩张后皮肤真皮层明显变薄，表皮层厚度与RTE组相比无明显变化；真皮层胶原纤维排列稀疏、纤维束细小；弹力纤维广泛断裂；Ⅰ型胶原含量减低。

A 46-year-old man presented with a gradually growing nodule on the left dorsal foot, which had been present for over 10 years. In the beginning, the lesion was treated as a keloid. Because of poor response to treatment, biopsy was arranged. Sections showed a dermal tumor composed of numerous foamy cells, hyalinized wiry collagen, spindle cells and entrapped collagen. The foamy cells were positive for KP1(CD68) and negative for S-100 protein and HMB-45. The histological and immunohistochemical results were consistent with the diagnosis of lipidized fibrous histiocytoma.

一位46岁男性从十年前开始於左足背上出现一个逐渐长大之结节，一开始被当作蟹足肿给予治疗，因为对治疗的反应不好，故安排了切片检查，病理显示一个由大量泡沫状细胞，坚硬而透明之胶原纤维，梭状细胞，胶原纤维束所构成的真皮肿瘤，免疫组织化学染色显示KP1(CD68)阳性，S-100 protein与HMB45阴性，综合病理与免疫组织化学染色结果，诊断为脂肪性纤维组织细胞瘤。

The result showed that after the treatment of the high-shear fiber kneader, the content of shives of the pulp will decrease 87％or more, the tensile index of the pulp sheets increases 22.6％, the tear index increases 28.8％, and the burst index increases 39.1％.

实验结果表明：纸浆中的纤维束去除率可达87％以上；纸浆纤维形态发生了变化，纤维的柔软度有所提高；纸浆的游离度略有下降，但对纸浆滤水性能影响甚微。

The relationships between strain and stress of several kinds of high strength fibers, such as Kevlar, Twaron and Dyneema were obtained, and the dependence of mechanical properties of fibers on the strain rate was gotten and explained from the microstructures and deformation mechanism of fibers. Then, the damage and failures of plates with the reinforcement of fibers under high velocity impacting were studied experimentally. Based on experimental results, a set of equations was presented to depicted the deceleration of penetrator. The dynamic response of fiber cluster and sandwich were simulated successfully with a new algorithm and code, which was developped by our group. The coupling effect of stress wave and thermal conduction could be considered with acceptable accuracy and CPU time.

其中，获得了以芳纶纤维为代表的7种纤维的动态应力应变关系，从材料微观机制解释了纤维束的应变率相关特征；得到了板材在高速冲击下的能量吸收机理，以及影响能量吸收机制转变的主要因素；发展了一种新型的原位光学测试技术，以之可以测量试件在冲击加载下的变形场及其演化，该技术除了在本项目应用外，还可以对剪切带的萌生演化、孔洞动态扩张规律进行较好的观察，以弥补相关研究中实验证据的缺乏；发展了含热传导的冲击动力学有限元程序，在侵彻、绝热剪切带、脉冲激光诱导结构破坏等问题的分析中得到了较好的应用。
