［Objective］To study the relativity during polyethelene debris cytokine and loosening of hip prosthesis.［Methods］Thirty eight patients with loosening of hip prosthesis were divided into three group:total hip arthoplasty,double hip arthoplasty and integrated arthoplasty.The inflammative reaction was analyzed with light microscopic observation arrording to the half-ration standard of Joseph,and the content of TNF in samples of interface membranes was determined.

Firstly, the model of distributed single-hop fully-connected FH-PRNs for missile systems is developed in this dissertation, which fully describes the physical and link level characteristics of the network. Common-transmitter-based spreading codes protocol and unslotted ALOHA channel access protocol are adopted, considering two types of services, i. e. Unacknowledged Data Packet and Acknowledged Data Packet.

首先，本文建立了战术导弹武器系统分布式单跳全连接跳频分组无线网的网络模型，所建模型充分地反映了网络的物理层和链路层特性，采用了公共码加发射码的扩频码协议及异步非时隙ALOHA信道访问协议，考虑了两类业务的情况，即无应答数据分组和有应答数据分组。

On the basis of the modification theory, relative modification concept of cycloidal gear pair and the appraisal index of the initial backlash are built to solve the problem that cycloidal gear works unsmoothly in pin wheel of the full-hydrostatic steering control units. The major goal of modification is a uniformity of initial backlash, so equidistance modification that has good effect on improving quality of fluid cycloidal pair is chosen.

为解决全液压转向器转子转动不灵活的问题，在分析现有摆线针轮啮合副齿廓修形理论基础上，建立摆线副修形的相对性概念和间隙分布评价指标，提出无系杆摆线副修形的主要目标应使初始间隙分布均匀，选择的修形方式为等距修形。

By Ensemble-averaged Method, the mean field was got to show the 3D structure of flow. By Phase-locked Averaged Technique, the periodic mean field was got to reflect the periodic unsteady characteristic. The 3D structure and the periodic unsteady characteristic of the unsteady flow within the vaneless and vaned diffuser were discussed through analyzing the mean field and the periodic mean field.
