Based on the ETA/VPG and LS-DYNA software platform and "vehicle-barrier-curve-road" integrated system dynamics model, in the research, the orthogonal experimental design method and the dynamic explicit finite element method were applied jointedly. The rear wheel elevation was considered as criterion for evaluation and six cross-sectional shape design variables were created. The application of L25 (5^6) orthogonal table for simulation and the use of SPSS statistical package help the variance analysis of simulation results, and the influence levels of various factors were studied to determine the optimal parameters of concrete barrier.

为此，以NJ型混凝土护栏尺寸参数为参考基础，以防撞等级为SS级的护栏为研究目标，以大型客车总质量为18t、碰撞速度为80km/h、碰撞角度为20°的碰撞条件为研究工况，基于eta/VPG及Ls-dyna软件平台及&汽车－护栏－弯道&一体化车－路系统动力学模型，联合应用正交试验设计方法及动态显式有限元方法，以客车后轮抬高量为考核指标，对控制弯道混凝土护栏截面形状的6个设计变量，应用L25(5^6)正交试验表安排仿真试验，借助SPSS统计软件包，对仿真试验结果进行了方差分析，找出了各因素对结果的影响程度，并据此确定了弯道混凝土护栏的最佳尺寸参数。

For the word of Hu Weiwu of total stylist of the core that use dragon, do a technology to need to start protracted war in certain moment, the idea early days that I design to working shedding system is do to satisfy the requirement of the market and client, and now is the research that plans to do endurance and development The friend that has industry the other day is flowing carefully in the problem that the trends in moving process revises about the job, say this demand is at present more, whether to know to get used to a design to you can satisfy this kind of requirement oneself?

用龙芯总设计师胡伟武的话来说，搞技术在某些时候需要搞持久战，我对工作流系统设计的想法前期是为满足市场和客户的需求而做，而现在是打算搞持久性的研究和开发前些天有业界的朋友在仔细关于工作流在运行过程中动态修改的问题，说目前这个需求比较多，不知道自适应设计是否能够满足这种需求？

Secondly, it devises the overall and each sub-systematic structure according to the general objective of the analysis of function demand and the design of the system.

At first, the rought C〓F〓 mixed gases are obtained by pyrolysis process of R22. A experimental pyrolysis device is designed and made by ourself. The optimum operating conditions are offered in the paper. Secondly, the much efforts is on the synthesis of R134. After through the discussion of basic thermodynamics and kinetics, selecting and preparating catalyst, it is possible that the synthesis of R134 by pyrolyzed gases hydrogenation. Base on the character of catalytic process, the kinetics equation about C〓F〓 catalytic hydrogenation is established. The rate constant of the reaction is obtained through experiment data regression. In order to achieve higher yield of R134, some optimum technological conditions is determined.

论文首先对R22裂解制成四氟乙烯混合原料气的裂解过程进行了讨论，自行设计和制作裂解反应装置，并确定裂解反应的最佳操作条件；然后，重点对R134的合成进行基础研究，分别从热力学和动力学的角度探讨以含四氟乙烯的R22裂解混合气为原料合成R134这一全新工艺的可能性，选择和制备加氢催化剂，根据催化过程特点建立四氟乙烯催化加氢反应的总包动力学方程，并在此基础上自行设计和制作中试合成装置，获得了以裂解混合气为原料合成R134的最佳工艺条件，为R134的工业化生产提供了必要的理论依据和实验基础。
