The main work is as followings: First, we use KE SI DA microscope for observing the appearance and configuration of bicomponent fiber. It was found in the bicomponent fiber it is a bilateral array for the PET and PTT. The cross section is anisomerous with PTT and PET side by side. After heat treating the shape of single filament becomes three dimensional curly and the number of crimp is biggest in the condition of relaxation. In the range of some tention, the bulkiness and crimpness fall obviously after the bicomponent fiber is treated with heat.

首先利用科视达观察了PTT/PET双组分复合纤维的外观形态，发现PTT/PET双组分复合纤维中PTT、PET两种组分呈双边分布，横截面呈不对称的哑铃状，PTT和PET两组分分居在横截面两侧，单丝经热处理呈现出三维立体卷曲，在无张力条件下卷曲数最多，在一定的张力范围内，随着所加负荷的增加，PTT/PET双组分复合纤维热处理后的蓬松性及卷曲性均下降显著。

The transverse longitudinal paper is paper long-due to the fiber bonding ability and fiber strength of coaction, has better resistance to tear strength not easily torn, tore his face appears ragged denticular, while the vertical longitudinal paper that only short-fibre bonding strength, easy to tear, students'rooms surface.

纵向纸的横向即纸张的长边方向由于纤维间结合力和纤维强度的共同作用，有较好的耐撕裂性能，不易撕裂，撕裂面会出现参差不齐的锯齿状；而纵向纸的纵向即短边方向只有纤维结合力，易撕裂，撕裂面较整齐。

According to the structure and property of feather fibre fabric and the sizing ingredients,choosing the biological catalyst-enzyme which has high catalysis efficiency and undivided reactivity,to desize the feather fibre fabric ,the paste would be removed quickly and efficiently.

在羽毛纤维织物结构性能基础上，结合织物上所含浆料的组成，选择催化效率高、反应专一的生物催化剂酶对羽毛纤维织物进行退浆处理，可以快速、高效退除织物上的浆料，同时酶退浆时反应条件温和，不需要高温、高压、强酸、强碱的作用条件；采用超声波对羽毛纤维织物进行退浆可以缩短处理时间、降低处理温度，减少药剂用量，而处理效果优于常规法退浆。

Establishing experimental animal model of immunized fibrosis could contribute to research on extracellular matri and cytokine. they turns out that the ingredient of Desmodium pulchellum can relieve extra growth and deposit of ECM and adjust the level of relative cytokine, such as TGF-β1 and IFN-γ, benefit to effect of hepatic anti-fibrosis.

结果证明排钱草生物碱类成分能减轻肝纤维化的基本病理改变即减少肝细胞外基质的过度增生和沉积，调节与肝纤维化密切相关的TGF-β1、IFN-γ等细胞因子水平，向着有利于减轻肝纤维化的方向发展。

Methods: We conducted a retrospective study of 100 patients surgically treated from 1964 to 1997, including 53 cases of abdominal wall desmoid tumor and 47 cases of extra-abdominal desmoid tumor.

回顾分析我院1964～1997年间外科收治的100例硬纤维瘤，包括腹壁硬纤维瘤53例，腹壁外硬纤维瘤47例。

From the beginning of 1980s, Non-asbestos Compressed Fiber Sheet wasdeveloped by some advanced countries as substitute of Compressed AsbestosFiber Sheet.It has been widely used as seal material in many different fieldsbecause of its good processing method and no harm to environment andpeople. Such material has diversity and devisable ingredient and performancesince non-asbestos fiber has wide selectivity and combination, which make peopleto pay close attention and take researches on it.

压缩非石棉纤维橡胶板(Non-asbestos Compressed Fiber Sheet，CFS)是八十年代初以美国为首的工业发达国家为替代传统压缩石棉纤维橡胶板(Compressed Asbestos Fiber，CAF)而开发研制的一类新型非石棉纤维增强密封材料，它不仅具有较好的加工工艺性，而且还具有对环境和人体的无害性，因此被广泛用于各行业密封的需要。

In the most caudal extent of the striatum, there was also a dense band of CGRP-positive fibers in the lateral border of the caudate putamen and the direction of the fibers was also dorsoventral. There are some transverse CGRP-positive fibers connecting the MrD and Cpu.

CGRP免疫阳性纤维分布越靠纹状体尾，则纤维越密集，且阳性带越宽；（2）在纹状体的最尾侧，除边缘区外，尾壳核的外侧缘也出现一条致密的阳性纤维带，与边缘区走向一致。

More TH and 5-HT containing fibers were found close to the ependyma than SP and L-ENK containing fibers.

SP和L-ENK纤维在中线处少，靠中线两侧的多，于是纵行纤维分成两条，并有纤维和末梢伸延至后角基部内缘处。

For those in control group (n=14), the animals did not undergo any surgery of the nerve fibers and ganglia. In Vi group (n=9), the animals underwent bilateral resection of the nasociliary and postganglionic parasympathetic nerve fibbers. In SCG group (n=8), the animals underwent bilateral resection of supper cervical ganglia. In V1+SCG group (n=9), the animals underwent both surgeries as Vi and SCG group did. In sham operation group (n=11), the animals underwent carotid manipulation with blunt-tipped forceps as well as dissection of nasociliary and postganglionic parasympathetic nerve fibers around the ethmoidal foramen, without cutting any nerves. SCS was performed on rats and CBF was monitored by laser Doppler flowmeter recordings.

Control group, the animal underwent SCS and LDF recordings without any surgery of the nerve fibers and ganglia. V1 group, the animal underwent bilateral resection of the nasociliary and post-ganglionic parasympathetic nerve fibbers. SCG group, the animal underwent bilateral resection of supper cervical ganglion. V1 + SCG group, the animal underwent both surgeries as V1- and SCG-group animals did. Sham group, the animal underwent the carotid manipulation with blunt-tipped forceps as well as the dissection of nasociliary and post-ganglionic parasympathetic nerve fibers around the ethmoidal foramen, but without cutting any nerves.
