Conclusion］1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?

［结论］ 1、各种假体植入后均在股骨距处形成较高的应力遮挡，而用弹性模量较低的CFR/PSF作为柄，其股骨相应区域的应力遮挡率较低，但股骨相应界面应力较大，而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理；相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别，实验表明力学因素并不是选择假体组合的主要标准。

The flyman dismounted at the steps, ascended them, and rang a brass-handled bell, which flew back to its socket with an angry metallic snap, as if it had been insulted by the plebeian touch of the man's hand.

马车夫下到台阶上，并从台阶走上去，按一个铜柄的铃，铜柄猛地向插座内一缩，发出一阵愤怒的金属声，仿佛这位庶民的手碰了它一下，它就受到了侮辱似的。

①The distance between handle of malleus and stapes, the dia_meter of manubrium mallei are important to the design of prosthesis.

①锤骨柄与镫骨头之间的最短距离及锤骨柄的直径对赝复物的设计具有指导意义。

In a reiew of three different types of titanium stems with tapered geometries, Mallory, Head, and Lombardi found an oerall incidence of roentgenographic proximal femoral bone atrophy of only 6% of 748 arthroplasties studied.

在对三种不同类型钛制锥形柄的综述中，Mallory、Head和Lombardi发现，748例髋关节置换术的X线片上仅有6％显示有股骨近端骨萎缩，且没有一例病人股骨近端骨丢失程度比植入柄远端为圆柱形填充骨干的假体的病人更严重。

An increase of intraoperatie fractures is reported with the introduction of uncemented stems and this is often a consequence of the effort to obtain a sufficient press-fit to gain initial stem stability.

已有报道，按照应用的固定方法，其术中骨折的发生率也不一样。据报道，非骨水泥柄的打入会增加术中骨折的发生率，通常这是为了努力达到充分的紧压贴合，以获得股骨柄的初始稳定的结果。

During the using study of handle of forceps and pancake turner this paper discovers that handle"s crooking is an important factor which affects product"s ergonomical performance and is helpful to improve the product"s usability, and that crooked angle of handle exists an optimum value, but the best crooked angle of handle of different product is different, if the optimum value is found the product"s using study should be done.

本文从镊子柄和锅铲柄的使用性研究中发现：手柄弯曲是影响产品人机工程学性能的一个重要因素，它对提高产品的可用性有着很重要的意义；手柄的弯曲还存在一个最佳角度。但是不同产品手柄的最佳弯曲角度是不相同的，倘若要获得某产品手柄的最佳弯曲角度，还必须进行该产品的使用性研究。

Learning to operate and cast with a spinning outfit is relatively painless and free from the frustration caused by backlashes.

学习操控直柄装备比枪柄的相对容易，也没有炒粉的麻烦。

Bell-shaped worms there is a unique long-handled-shaped organ attached to the fish through its body one end of the handle attached parasites.

钟形虫长有一独特的长柄状器官，通过它附着在鱼身上，柄的一端连着虫体。

By inputting a vertex set which belongs to an edge track around the tunnel to be cut into CutTunnel operation algorithm, the algorithm deletes all the edges connected to the vertex in vertex set. Thus the tunnel is cut. CreateTunnel operation is the reverse operation of CutTunnel.

CutTunnel操作算法通过输入环绕待切断柄的1条封闭轨迹的顶点集合，然后删除所有与这些顶点相连的边，从而切断1个复杂的柄。

In addition, many studies of patients with AVN showed plenty of special characteristics,such as age distribution and bone quality.Objective:To study the geometric features of proximal femur for the Chinese AVN population,in order to prove the existence of special characteristic of proximal femur for the disease and then develop an AVN-specialized stem evaluated by a validated finite element analysis.Methods:1.The author investigated the standard X-ray data of 127 cases(179 hips) with definite diagnosis of AVN to provide anatomical references for this disease.At the same time,we conducted a meta-analysis of anatomical studies of normal proximal femur data,including the section of LT+20,LT,LT-20 and CFI to identify the potential difference between AVN and normal population.

方法1、通过研究AVN患者标准X线正、侧位片127例(179髋)，获得股骨近端的解剖学数据，利用荟萃分析的方法比较AVN患者股骨近段髓腔特征平面(LT+20，LT，LT-20)及CFI的改变与以往研究数据的差异，并利用创伤性FNF患者资料代替正常人股骨数据进一步比较髓腔前、后、内、外四条曲线段上的差异。2、通过结合现代CAD技术，将内、外、前、后曲线拟合到AVN柄的外形上，选用短柄假体设计，近段设计利用AVN患者骨髓腔CT相对应位置的断面进行修正，设计AVN人工股骨柄。3、计算机三维有限元分析：①使用CAD软件SolidWorks和有限元软件Ansys所建立的髋关节股骨侧假体置换后的三维有限元模型。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
