巴黎历险记

Part Five: Iron Cage and AtticV.铁笼与阁楼Before reaching my imagined destinations: the 8th district where the Elysee Palace and the Matigon Hotel were situated, the van stopped in front of an old building in the 6th district, near the Church Saint-Germain. It was a police station. Of course there was no red carpet out for me. The waiting hall was an iron cage where there were already plenty of sardines(沙丁鱼). The cage was so full that my bodyguards had to cram (填满) me into it, boxed in with at least 15 people. It must have had the highest population density(人口密度) of anywhere in the word. Squeezed in among the others, I could hardly breathe and soon was dripping with sweat. The waiting time was long; one minute seemed to me a century.     

A Little Dog

When I was ten years old, a little dog called Xueqiu came into my life as a birthday present. It was a pretty dog with long white hair. And the hair felt very soft. At first I hated it, because I didn't like animals at all. But wherever I went it always followed me as if it liked me. Slowly and slowly, I began to like it, too. One day, our family were going to my grandma's in our car without taking Xueqiu. But after we drove more than twenty minutes, the dog suddenly came out from under the seat. That made us laugh happily. My father said,"Xueqiu brings us not only happiness but also surprise."One evening it was time for dinner, but I couldn't find my little brother. My parents were worried about him. At that time, Xueqiu came back. It cried loudly, and then ran out very fast. I ran after it. A long time later, I saw my brother. He was badly hurt in his right leg. Looking at him, I felt very sad. Then I took him to a hospital for treatment. From then on, Xueqiu became a pet in our heart. It was a clever dog. It even warned me not to pollute the environment. Not too long ago, I threw about some rubbish in a park. It went on shouting until I picked it up and put it into a dustbin. Then it looked at me with a smile.     

Multi-objective optimization design method of the high-speed train head

With the continuous improvement of the train speed, the dynamic environment of trains turns out to be aerodynamic domination. Solving the aerodynamic problems has become one of the key factors of the high-speed train head design. Given that the aerodynamic drag is a significant factor that restrains train speed and energy conservation, reducing the aerodynamic drag is thus an important consideration of the high-speed train head design. However, the reduction of the aerodynamic drag may increase other aerodynamic forces （moments）, possibly deteriorating the operational safety of the train. The multi-objective optimization design method of the high-speed train head was proposed in this paper, and the aerodynamic drag and load reduction factor were set to be optimization objectives. The automatic multi-objective optimization design of the high-speed train head can be achieved by integrating a series of procedures into the multi-objective optimization algorithm, such as the establishment of 3D parametric model, the aerodynamic mesh generation, the calculation of the flow field around the train, and the vehicle system dynamics. The correlation between the optimization objectives and optimization variables was analyzed to obtain the most important optimization variables, and a further analysis of the nonlinear relationship between the key optimization variables and the optimization objec- tives was obtained. After optimization, the aerodynamic drag of optimized train was reduced by up to 4.15%, and the load re- duction factor was reduced by up to 1.72%.

The history of Cat and Mouse

Long long ago,a cat and a mouse were good friends. They ate together, played and slept together. They were the best friends in the woods. 　But one day, they weren't friends forever. Fairies wanted to campaign for the 12 symbolic animals associated with a 12-year cycle. The cat and the mouse both went to campaign at the appointed time. The morning in the second day the mouse was boring: Should I go to the campaign with the cat?And should I go to call him?The cat was a lazy animal: He was still sleeping now. And the mouse didn't want to call him up. Finally the mouse was the first animal in the 12 symbolic animals associated with a 12-year cycle. But the cat was not. So today cats always want to catch mice and eat them. Because they remember this history: Mouse forsook cat!

一次不可思议的经历

It was a busy scene in the street when the Spring Festival was drawing near. I was helping my wife sell the goods at her stand when there were too many buyers around. One old woman, with her both hands occupied, was picking out trousers all by herself. She was wandering which one to take. She spent so long in choosing that I lost patience. So I just left her alone and turned to greet another guest. At the same time I saw a group of guys walking towards our stand. I was glad that we could make a little more today before my wife whispered into my ear "WATCH OUT!". "WHY?" I asked loudly. "Shoo-." my wife held her finger up to stop me and rolled her eyes at me when she quickly covered the moneybag tightly. "What?" I still wanted to find out the reason when the guys stood around the old woman. The guest I served left without buying anything though he liked the item very much.
