The main content of the dissertation is designing and realizing the total scheme and frame of system software. The module of the input and output is designed by using the generally I/O of the multichannel buffered serial port to simulated the communication of I~2C bus. The Ping-Pong buffer is brought forward to resolve the problem of the data rate matching. The logic switch function is designed in the programmed logic devices. The data transmission rate is improved by using the DMA and the dual buffer mechanism. The system program self-loading is realized by the design of the self-leading program. Lastly, the dissertation analyzes the characteristic of LLL video and experimentalize with some typical image processing algorithm.

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。

Refers to the independence of failure to complete a single chip damage; the relevance of failure means a failure associated with some other fault, the fault is not normal for many functions, and its failure to control the various functions of the substance of the common part of malfunction caused by (for example, soft, hard disk subsystem is not working properly, and the soft, hard disk controller to control the functions of the more isolated, fault is often on the motherboard that control peripheral DMA data transfer control circuit).

独立性故障指完成单一功能的芯片损坏；相关性故障指一个故障与另外一些故障相关联，其故障现象为多方面功能不正常，而其故障实质为控制诸功能的共同部分出现故障引起（例如软、硬盘子系统工作均不正常，而软、硬盘控制卡上其功能控制较为分离，故障往往在主板上的外设数据传输控制即DMA控制电路）。

Occasionally like to play classic DOS games under the friends may have PCI sound cards can not be normal in the DOS sound issues, this is because DOS is not compatible with the original IRQ, DMA interrupt, resulting in PCI sound card can not support by the Sound Blaster standard design procedures.

喜欢偶尔玩一下DOS下经典游戏的朋友可能会遇到PCI声卡在DOS下无法正常发声的问题，这是因为在DOS下不兼容原来的IRQ、DMA中断，导致PCI声卡无法支持按Sound Blaster标准而设计的程序。
