According to the calibration information, Research and development status of automotive bus network and automotive calibration system is studied and the research significance is generalized. First of all, the collectivity precept for calibration system is designed, the calibration platform is set up based on the XCP Protocol and the calibration object is CAN bus network simulation ECUs. Then how to create the calibration system based on Ethernet and Series communication is expatiated, the communication way from computer to ECUs is introduced and the calibration system is tested. Then how to create the calibration system based on CAN bus communication is expatiated, the design and the interface programme are introduced and the calibration system is tested. At last the platform is used to calibrate the CAN bus network simulation system to regulate the simulation system's topology and communication speed to test the communication protocol's feasibility.

论文首先设计了标定系统的总体方案，以CAN总线实时仿真系统中的节点标定为研究对象，采用XCP协议建立具有串口、以太网和CAN总线三种通讯接口的标定平台；然后，具体开发了基于以太网通讯和基于串口通讯的标定系统，完成了上、下位机部分的软件设计，确定了标定系统在两种通讯方式下的数据处理方法，并分别应用两种标定方式标定下位机仿真系统的参数，让下位机仿真系统在规定的通讯协议和拓扑结构下进行仿真，对所设计的标定系统进行了调试；接着，设计了基于CAN总线通讯的标定系统，完成了CCP协议（&XCP on CAN&）的接口程序设计，并通过混合动力汽车一种拓扑结构的通讯仿真对所设计的系统进行了调试；最后，应用开发的标定系统，对混合动力电动汽车网络通讯协议进行了仿真研究，并根据实验结果进行了分析。

Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。
