The formation mechanism of the screw structures on the surfaces of polytype crystals is discussed according to the theoretical model of anionic coordination polyhedron growth units.

本文用负离子配位多面体生长基元理论模型讨论了多型性晶体表面螺旋结构的形成，提出在多型性晶体中配位多面体呈层状分布，配位多面体的面为层的边界，上、下层负离子配位多面体不是呈镜象对称的，在三方晶系和六方晶系的晶体中是沿晶轴a、b错开，上、下两层负离子配位多面体体呈交叉对应，从而达到稳定平衡。

If θ=0?＃, it means that whisker axis is perpendicular to crack face, the energy dissipation caused by whisker-bridge join in zone of crack end achieves its maximum and the reintoughening effect of material achieves the best of all; along with growth of angle θ, the maximum principal stress in the matrix of whisker roots increases, when it achieves its limit, the whisker will be broken and orientation effect will be weakened.

当添加晶须与裂纹面法向形成角度θ时，随角度θ的增加，裂纹尖端拉应力增加。当添加角度较大时，晶须根部基体承受了较大的应力，易遭到破坏性崩裂。同时，晶须内部主应力与晶须轴向之间的角度也随角度θ的增加而增加，造成晶须折断，致使造成晶须拨出的体积分数φap减小，降低了增韧效果。

Finally, the surface hardness and metallographical structure were measured and analyzed. The results show: the surface hardness of slight protuberance than the matrix has been improved by 30%-40%.

最后对毛化模具表面硬度和金相组织状况进行了测量和分析，结果表明，微凸体表面硬度比基体材料的表面硬度提高了30%-40%。

Caution: adding aluminized tape to a punch or cavity will most likely requiring grinding the mating half respectively.

In recent years, due to industrial structure changing rapidly, enterprises face the situation that the industry has been relatively mature and even recessional, they invariably deliberate on how to reduce cost and adjust enterprise constitution.

近由於产业结构迅速变化，企业在面产业日趋成熟、甚至衰退的况下，无亟思如何低成本、调整企业体质，因此产业型态与雇用模式亦出现有别於以往的变化，组织规模渐趋向精简与扁平化、专营於某块专业基的顾问业纷纷崛起，加上求职者工作价值观的改变，终身雇用制之式微等等现象，许多企业纷纷采行各种措施，如组织再造、缩减规模与劳动弹性化等，期望能专注於本身专长的核心优势，并将非本身专长的工作以外包的方式来降低成本。

Otherwise, Trans-Golgi complexs show the shape of flat vesicle variance and content residual.

高尔基体扁平囊形态变异，内容物的潴留。粗面内质网，腔扩张，核糖体脱颗粒。

These two defects were suppressed when polyurethane elastic cushions and steel paddings were used between the titanium alloy retiary sheet and the press punch with the blankholder device in the forming technology mode, and the 3D curved surface of prosthesis with good quality can be acquired.

模拟结果表明：采用前两种成形工艺得到的钛合金颅骨修复体表面出现压痕或起皱缺陷，采用在基本体和钛合金网板之间放置聚氨酯弹性垫和钢质垫板并使用压边圈这种成形工艺时，可以抑制压痕和起皱的产生，获得良好的成形效果。

The simple internal faade, with marble revetment , the sacristy and the library are Michelangelo's designs but he never carried them out.

简朴的内表面带有大理石护面，圣器收藏室和图书馆设计出自米开朗基罗之手，但是他从没有亲手实践过。

The method which is composed of pre-impregnating in soaker, painting coating on the surface of carbon/carbon composite, and solidifying the coating, was first used for the preparation of a good anti-oxidation coating on the composite.

摘 要：采用在C/C复合材料基体表面预先浸涂浸渍剂，再涂刷涂层并进行涂层固化处理的工艺方法，可制备出抗氧化性能良好的涂层。
