(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

Typically, capitellar fractures are divided into 3groups3,21: type 1, the Hahn-Steinthal fracture, is characterized by a single, large capitellar fragment; type 2, the Kocher-Lorenz or Mouchet fracture, involves the articular cartilage and a thin layer of subchondral bone; type 3 was originally described by Broberg and Morrey and characterizes a comminuted or compression fracture of the capitellum.

肱骨小头骨折可典型地分为3种：1，Hahn-Steinthal骨折，特点为单个、大块小头骨折片；2，Kocher-Lorenz 或 Mouchet骨折，涉及到软骨和软骨下骨骨折；3，此类骨折最初为Broberg和Morrey所描述，特点为肱骨小头粉碎性或压缩性骨折。

We compare and analyse these methods by Monte Carle simulation method on computer.

在多因素控制与诊断方面，本文将两种质量诊断理论的思想应用于多因素诊断，提出了多因素选图与休图相结合以及单因素选图与休图相结合的两种多因素诊断方法，指出了现有多元质量控制方法中存在的缺点，并提出了逐步诊断的思路和三种用于多因素诊断的逐步诊断方法，即顺序统计量逐步诊断法、最小距离逐步诊断法和两种质量逐步诊断法，然后通过统计模拟进行了分析和比较。

With the concept, the fractional lower array power is formulated and it is theoretically proved that the power is finite and reasonable for beamforming, provided thatthe fractional order does not exceed the half of the noise characteristic exponent.

根据分数低阶统计量和零阶统计量，这部分提出强冲击噪声环境下表现出稳健的波束形成性能的三种新的波束形成算法：分数低阶最小方差无畸变响应波束形成算法、线性约束最小几何功率波束形成算法和最小几何误差波束形成算法。

Three classes of equivalent system methods which are used in finding high order flight control systems low order equivalent are studied. The first class methods are the classical frequency domain-based equivalent system methods which recommended by MIL-F-8785C and MIL-STD-1797A. Five longitudinal low order equivalent systems and fourteen lateral ones are discussed in detail and some pieces of advice are given. Also conduct an investigation in the time domain-based equivalent system methods .

研究了求取高增稳飞机的低阶等效系统的几种方法：研究了经典的频域等效系统方法，针对纵向5种、横向14种构型的低阶等效系统进行了拟配实践，并提出一些有益的看法；以频域等效系统方法为基础，提出了时域等效系统新方法；以最小二乘辨识为基础，提出了两种纵向短周期低阶等效系统时域辨识方法(等效延迟时间τ_q参与或不参与)。

The average heterosis of spike number per plant and 1 000-grain-weight were high and obviously related to yield heterosis at 0. 01 and 0. 05 level, respectively; the average yield heterosis of F1 hybrids between common wheat and club wheat was 77. 19%(ranged from-2. 18% to 143. 42%), the average heterosis of spike number per plant and spike grain number were high and both was also obviously related to yield heterosis at 0. 01 level.

结果发现：小麦种间杂种在产量上具有明显的杂种优势，其中斯卑尔脱小麦与普通小麦所配的30个种间杂交组合产量杂种优势平均为109.24%(43.14%～187.96%)，单株穗数及千粒重平均优势较大且与产量优势的相关分别达极显著水平和显著水平；密穗小麦与普通小麦所配的30个种间杂种的杂种优势为77.19%(-2.18%～143.42%)，单株穗数和主穗粒数优势较大且与产量优势的相关均达极显著水平。

It is defined that the two integrating ways' characteristics of the wavelet NN and theirs applying on the equipments' intelligence diagnose. Wavelet analysis technology has the ability of analyzing strongly the non-placidity signals' time-frequency, self-studying the NN, of dealing with data distributed and collaterally, of mapping non-linear ability, and it is fit for diagnosing failures.

利用小波分析对非平稳信号强的时频分析能力和神经网络的自学习、分布式并行处理数据及非线性映射能力，以及它们适合于故障诊断的特点，说明小波与神经网络的松散型和和紧致型结合途径下产生的两种小波神经网络的各自特点及其在设备智能诊断中的应用。

The air conditioner forced draft fan ventilates the way to have longitudinal and the crosswise two kinds generally, the lateral ventilation the air current overflow sectional area is big, the wind speed is small, easy to create the big area the dead angle, but longitudinal ventilates the air current the overflow sectional area to be small, the wind speed is big, the dead angle area is very small.

冷风机通风方式一般有纵向和横向二种，横向通风的气流过流断面积大、风速小，容易造成较大面积的死角，而纵向通风气流的过流断面积小，风速大，死角面积很小。在使用条件许可的情况下，应该尽可能采用先进的纵向通风方式。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
