It was found that these as-prepared MgO materials replicated the biomorph of pinewood, and their frameworks were constructed by plenty of claviform nanoparticles with a similar sectional area, which were different from those of MgO prepared by directly thermal decomposition of MgO precursor.

结果表明，用该方法制备出来的MgO样品具有松木的生物形态，由横截面积比较均一的棒状纳米颗粒构成，不同于乙酸镁直接焙烧得到的MgO样品。

However, we don"t find neither the economies of scale nor the diseconomies of scale in the investment banking industry. What"s more, the scope of Chinese investment banks is too narrow and the income relies on the traditional deals too much, which makes the industry far from the economies of scope.The dissertation starts from restrict-pricing model of Spence and Bain-Sylos and analyzes the mechanism of the strategy of excessive production capacity. And based on the extended dynamic game theory of Dixit the dissertation establishes the dynamic game theory model of capital promise and entry deterrence. The dissertationillustrates the essence of scale strategy of Chinese investment banking industry: Firstly domestic investment banks should optimize the capital structure and the scale expansion by proper financing arrangement.

本文对我国投资银行业的产业绩效进行了实证检验：市场结构、行业规模以及市场总体收益率对行业的利润率具有很强的解释能力，从影响的相对水平来看，集中度的影响要大于市场收益的影响，同时，规模的影响与集中度、市场收益的影响相反；同时，基于规模经济的横截面分析表明，我国投资银行业的经济规模与其绩效之间还不存在明显的关系；而且，我国投资银行业总体上经营范围狭窄，业务内涵单一，在收入构成上过分依赖于传统的三大业务，也远远没有发挥出行业的范围经济优势。

As compared with the drawing method intro-duced by Donal M.

他在书中介绍了在地形起伏情况下作褶皱横截面图的方法，但在某些情况下应用有局限性，作图方法较为复杂。

Methods: The distal 1/3 of eighty humeri was scanned by 16 layer spiral CT. The morphologic features of the intramedullary bony prominence above the olecranon fossa were observed and described on coronal, sagittal and transverse section after three-dimensional reconstruction. Then the distal 1/3 of twenty humeri was splitted vertically along the coronal midline for observing the intramedullary bony crista.

应用16层CT对80根肱骨远段1/3进行扫描，三维重建成像后，从冠状面、矢状面和横截面观察并描述鹰嘴窝上髓腔内骨性突起的形态特点，然后将20根肱骨远段1/3在冠状面上从中线纵行剖开，对髓腔内骨嵴行直观的观察。

Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.

选择成人尸体髋关节行CT成像得到髋关节每层横截面图像，提取边界坐标，利用有限元分析软件Unigraphics NX 2.0和Solid-Works 2006 SP0.0构建出髋关节三维有限元模型及人工髋关节假体，并模拟全髋置换术进行装配，将坐股韧带按其术中重建位置进行构建骨骼与金属模型采用三维十节点四面体实体单元进行网格划分，关节囊六面体连接单元划分，模拟坐位腿交叉动作载荷获取假体撞击过程的角活动度和相应的von Mises应力分布情况结果所构建的多体连接、大界面划移、大变形的坐股韧带重建有限元模型，客观反映坐股韧带真实解剖形态及生物力学行为，增加坐股韧带重建的模型其关节面的最大主应力值大于仅有金属的模型。

Bamboo first crystallizes then lignifies during bamboo shoot growth and basically forms crystal structure in one month. 1-year-old bamboo culm ends growth and its height,thickness, volume almost change little, but culm tissue is small and tender and there is more water and less substance in it. Bamboo crystal proportion keeps invariable during this period.2-year-old bamboo culm begin to lignify,its cellulose proportion debases and its crystal proportion decreases. Bamboo lignin debases, crystal proportion changes a little in the end of this period.Many-old-year bamboo culm crystal proportion is almost invariable. Freaky bamboo cell wall crystal region's thickness is less than normal bamboo's. Bamboo cross section crystal area and the ratio of long axis to short axis are less than normal bamboo's,and roundness,irregular index, the fiber cap density per unit area increase more than normal bamboo's.

竹笋生长阶段是先结晶后木素化的过程，一个月内细胞壁结晶组织基本形成；2）一年生竹材的植株秆茎生长结束，秆茎的高度、粗度和体积变化不大，但秆茎的组织幼嫩，含水量高，干物质少，竹材结晶度基本不变；3）二年生竹材的植株开始木质化，纤维素比例降低，结晶度减少，到后期竹子木质化降低，竹材结晶度变化不大；4）多年生竹材的结晶度没有太大的变化，结晶度大小处于波动状态；5）畸形竹材纤维帽细胞壁结晶区的厚度比正常竹小，其横截面结晶区的面积、纤维帽长轴与短轴比有所减少，而圆形度、异型指数有所加大，单位面积纤维帽的密度增大。
