With reading a mass of the documents about the rolling resistance and wet anti-grapping, there are 11 types semisteel belt tyres formularies designed in this paper by changing carbon black and SBR1502/SBR1712/BR9000 blending ratio, which answer for the actual demands of the tyre industry and have a certain extent engineering practicability.The DMA curves of 11 types tread rubber materials used in tires with the changes of temperature have been obtained by using Dynamic Mechanics Analysis technique on NETZSCH DMA242 instrument.

本文采用动态力学分析法，使用NEZSCH公司生产的DMA242型实验仪，获得了11种胎面胶的DMA温度曲线，从炭黑和生胶配比变化两方面，分组对不同系列的胎面胶的储能模量—温度曲线和损耗因子—温度曲线进行了分析比较，并参照1#胶料，对11种胎面胶—10℃～10℃和50℃～80℃的tanδ进行比较，讨论了炭黑及SBR1502/SBR1712/BR9000并用比的改变对胎面胶滚动阻力、湿抓着力的影响；在动态力学分析实验的基础上，还获得了11种胎面胶的生热率曲线，并分组进行了比较，研究了配方与生热率的关系。

Results The score of openness of sexual thought was 3.38±0.71, diversity of sexual behavior was 2.83±1.06, acceptant of sex trade was 2.16±0.61, alterative of sex objects was 1.89±0.65 and abundance of sexual knowledge was 3.11±0.75; Male's scores were ...

结果被试总体性观念各因子的得分在1.89±0.65～3.38±0.71之间，即性思想开放性、性行为多样性、性交易接受性、性对象可选性和性知识丰富性；上述因子的得分，男生显著高于女生；四年级显著高于一、二、三年级；城市生源学生显著高于农村生源学生；性观念因子高分组与低分组的被试在心理健康因子上的敌对和偏执上差异显著，前者得分高于后者。

Results: The pollution of amnionic fluid, the incidence of Apgar≤7 after 1 minute and the perinatal mortality rate in the group of BPS≤5 were significantly higher than that in the group of BPS≥6 (P.05). To predict dysplasia with ultrasonic score of BPS, the positive predictive value, negative predictive value, specificity and sensitivity were 93.94%, 78.68%, 98.57%, 65.58% respectively.

结果 声振刺激后胎儿BPS超声评分≤5分组中胎儿羊水污染率、1min Apgar评分≤7分发生率、围生儿死亡率均明显高於BPS超声评分≥6分组(P.05)，声振刺激后胎儿BPS超声评分预测胎儿结局异常阳性值、阴性值、特异度、敏感度分别为93.94%、78.68%、98.57%、65.58%。

Methods: From December 2007 to October 2009,365 cases in affiliated hospital after choledochotomy with exploration and T-tube drainage were randomly divided into 5 groups: experiment group1-4（G1-G4） and control group.

AFDX is applied in aviation and spaceflight field more abroad with its unique advantage, but because of its communication model, It can't satisfy the requirement of divinable and low latency of the real-time mission, The research of real-time of AFDX has became a important task, To improve the real-time of the network, the most doable method is to adopt the priority management model. This paper analyzes the issue of packet transmission with different priority; gives the average queue time and stay time of packets with different priority under two queue models and gives the computer simulation.

航空电子全双工交换式以太网以其独有的优势在航空航天等领域的应用不断扩展，但是由于通信模式，无法满足实时任务的可预测性和低延迟等要求，因此，研究AFDX的实时性成为一个重要的课题，为了提高网络的实时性最可行的措施就是采取优先级管理模式，对具有优先级的分组传输问题进行了分析，给出了两种优先级排队模型下，不同优先级分组的平均排队等待时间和平均逗留时间，并进行了计算机仿真。

On the foundation of successful 16×16 photonic switch module, the architecture of large capacity photonic ATM switch is studied in chapter 4. A new method is proposed, which can reduce hardware cost of the growable ATM switch by introducing pair-input share fanout units before interconnect stage. This new architecture is called pair-inputgroup-interconnect ATM switch.

在研制成功16×16光学交换模块的基础上，第四章研究了大容量光电ATM交换系统的体系结构，提出了一种可有效减少可扩展ATM交换系统中互连机构硬件开销的方法，即在分组互连级前引入双输入共享扩展单元，从而得到了硬件开销较小的双输入分组互连可扩展ATM交换结构。
