Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

本文首次在扫描电子显微镜下对比研究经化学浸解获得的碳质管胞和矿化的管胞腔铸体，明确揭示出了G-型管胞壁层和穿孔的显微结构：1）Hsüa reflexa次生壁木质化层的组成不均一，分为S〓、S〓和S〓层；穿孔腔为哑铃形，腔壁光滑；2）Huia gracilis的穿孔腔收缩，腔壁上发育次级穿孔，孔口具有边缘加厚。

This paper introduces a new process in which the T-outlet flange is formed from the metal main pipe with spe-cial revolving draw equipment,makes certain the shape of prefabricating hole,and presents the simple for-mulas of calcu lating process parameters of hole.

Before transecting inject 1ml Sodium Chloride in the epineurium. Annular tensile the proximal of epineurium with microscopic forceps annular shear the epineurium 7mm before broken ends with microscopic shear and stretch the epineurium until the two ends distance is 5mm.Use 8-0 suture line to bridge the nerve gap and make a 5 mm nerve tube at the proximal nerve end. Interrupted suture the epineurium tube and the distal nerve end make a 5 mm nerve mamuro for the injury nerve.Results: Postperative observation lasted for 6 weeks regeneration nerve through the 5 mm nerve mamuro.

在大鼠的坐骨神经距股方肌下缘15mm处，用1ml注射器向神经外膜下注入1ml生理盐水，然后于此处切断坐骨神经，用显微镊环形拉伸近端神经外膜，在距断端约7mm处用显微剪环形剪开神经外膜，并继续拉伸外膜使外膜两断端间距约5mm停止，用8-0的无损伤缝线桥接神经外膜两端，在神经近端形成约5mm的神经外膜管，将神经外膜管与神经远端间断缝合，使断伤的神经束间留有5mm的小间室。

She is shaped microfiber nylon bristles brush clearance axis function, with the function and application of clean water rolling every blade of tongue pressure to offset the removal of adsorbed functional integration, Trinity, and its fiber bristles of the softness and flexibility of the blade of tongue cleaning pursuit of the finer more comfortable, more clean brush principle, to create a S, C, L, M, U-shaped fiber brush tube axis by measuring the quality of Shenzhen Institute of test showed that the degree of its cleaning, and can be used as blade of tongue and mucous membrane, such as wrinkle-wall soft-tissue-specific cleaning products.

她是将异形超细纤维尼龙刷毛轴的清刷功能，与水流清洁功能和运用滚动隔压以抵消舌面吸附的清除功能相融合，三位一体，其纤维刷毛的柔软性和弹性，对舌面清洁追求越细越舒适、刷得越干净的原则，制造出S、C、L、M、U形纤维的管型轴刷，经深圳市质量计量检测研究院测试表明，其清洁程度好，可作为舌面及粘膜皱壁等软组织的专用清洁产品。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

在诱导条件下，这些突变体表现出不同的形态和结构的变化，共有22个表型和结构发生变化。20个突变系发芽率或存活率较低，发芽率由10％—60％，其中2个突变系存活率分别为0％和50％。5个突变系在茎或下胚轴的结构上发生变化，其中一个突变系arris-stem发生如下表型变化：从真叶出现至开花结实的整个生长期，生长速度要明显比野生型拟南芥缓慢；叶缘有明显锯齿，莲座叶呈螺旋状排列；茎的基部有较多侧枝，侧枝间距明显缩短，茎有明显扭曲；突变体茎侧面有1至数条棱形突起，内部存在一至数个排列紧密的细胞团，由多层细胞呈环形排列，细胞壁明显加厚，内部存在管状分子，推测为维管组织。
