月光恶魔     
I stood on the hill all alone. Staring at the full moon.I was bare-footed and only wearing a thin summer dress that blew in the cold northeastern wind.The cold bit at me but I had no care.As I had been wishing the full moon was growing brighter with every passing moment. The moon was almost as bright  相似文献

(A) One day, Mr Black went into a restaurant. He put his coat on achair near the door. There was nothing in the pockets of his coat. Afterhis meal he put on the coat, then he found there was much money in oneof his pockets. He immediately realized that someone else had taken hiscoat away by mistake. “Whose coat is this?”he thought. He saw a waiternear the door, so Mr Black said to him, “Somebody put a lot of money inmy coat. I have no time to wait for him. I have to go. Return it to him,please.”The waiter took the money and went away. A moment later, an-other man came with a coat just like Mr BlackKs. “IKm sorry, ” said theman. “I took your coat and you got mine. Please give me my coat and the  相似文献

Using FEM to predict tree motion in a wind field   总被引:1,自引:0,他引:1  
In this paper we propose a finite element (FE) simulation method to predict tree motion in a wind field, Two FE tree models were investigated: One model was generated based on a realistic nature-looking geometric tree model, and the other was a symmetric model to investigate the influence of asymmetric material properties on tree motion. The vortex-induced vibration (VIV) theory is introduced to estimate the fluctuating wind force being exerted on tree stems and the fluid-structure interaction (FSI) analysis is also included in the simulation. The results indicate that asymmetric material properties result in the crosswind displacement of the investigated node and the main swaying direction deviation. The simulation reveals that under wind loading, a tree with leaves has much larger swaying amplitude along the wind direction and longer swaying period than a tree without leaves. However, the crosswind swaying amplitude is mainly due to branch interaction. The numerical simulation proved that the interaction of tree branches can prevent dangerous swaying motion developing.  相似文献

A couple of years ago, when I was going tocollege, I volunteered to be a finish-line "hugger" atthe Kentucky Special Olympics held in Richmond1.Because I was studying to become a special-educationteacher, I was very interested in the games and thepeople and wanted to be more involved.The day of the event dawned dreary, wet andgray. I arrived early and watched as the participantsarrived with their families, friends and school groups.Even though it started to rain and a cold wind blew,I didn…  相似文献

My Magical Coat     
I had a magical coat. One day when I was walking in a street, I saw a poor vagabond (流浪汉).He was begging. I gave him my magical coat. He put it on, and then he became happy and got love from his family. Since then, he has lived a busy and happy life every day. Some years later, he saw a boy crying in a street. He asked the boy, "Hi, boy.  相似文献

The north wind and the sun are good friends.But one day they quarrelabout something. “I am stronger than you.”the cold north wind says.“Indeed you arenot.I’m stronger than you,”answers the soft,warm sun. Just then they see a man walking along the road. “I can get that man’s hat off his head,”the wind says.  相似文献

Jokes     
A Dirtier HandWhen he was a child, Mike did not always obey the rules of school. One day the teacher caught him breaking a rule and asked him to come up to be punished. In that school beating the palm of hand(手掌心)with a ruler was the punishment. Mike蒺s hands were very dirty, so on the way to the teacher蒺s desk, he wiped one of his hands on his coat.The teacher looked at it for a moment and said,“Mike, if you can find a dirtier hand in the class, I shall not punish you.”“Here it is…  相似文献

We investigated wind-induced vibration control of long-span power transmission towers based on a case study of the Jingdongnan-Nanyang-Jingmen 1 000 kV transmission line project in P. R. China. The height of the cup tower is 181 m with a ground elevation of 47 m, which makes it a super flexible and wind-sensitive structure. Therefore, we should analyze the wind- resistant capacity of the system. We simulated applicable transverse fluctuating wind velocity field, developed a lead-rubber damper (LRD) for controlling wind-induced vibration of long-span transmission towers, deduced LRD calculation model parameter, and researched the best layout scheme and installation method of LRD. To calculate the wind-induced response of tower-line coupling system in seven layout schemes, we used the time history analysis method, and obtained the efficiencies of wind-induced vibration control. LRD deformation research proved that the damp of all LRDs was efficient under the designed wind velocity when they were laid along the edge of tower heads. We studied the controlling efficiency resulting fTom only applying stiffness to the tower polos where the dampers used to be laid under the designed wind velocity. The results show that the controlling efficiency was not ideal when the stiffness is increased on the poles only. Therefore, LRD should conlxibute to both the stiffness and damp of a structure to effectively reduce the dynamic response of a tower-line coupling system under strong winds. We also discussed the controlling efficiency of LRD under static winds. The results show that there was little difference between displacements derived by the finite clement time history method and those obtained by static wind method conducted by a design institute. This means the simulation on space relevant wind velocity field was accurate and reasonable.  相似文献

It was a weird kind of desert. The "sand" was a bed cover of the cleanest white, only without edges. As the wind blew across it, dunes undulated exactly like folds left by a body on a bed.  相似文献

We carried out a wind tunnel test to measure cladding loads for a high-rise building of 295 m in height, which would be located in the business center of Chongqing Municipality, P. R. China. The rigid model was used to determine fluctuating local pressures on the exterior surfaces of the building. The wind tunnel test results show the cr/tical zone of wind pressures on building surfaces in both standalone and interference conditions. The computational fluid dynamics (CFD) was conducted by using the FLUENT Code to compare with the wind tunnel test results, and the steady three-dimensional turbulent flow with Realizable k-ε as a turbulence model was used. The CFD results are agree with the wind tunnel test results in regards to distributions of wind pressures over a high-rise building's surfaces.  相似文献

The FishermanA Fisherman went to a river to fish, and, having laid his nets across the stream, he used a stone and a long cord to beat the water in order to drive the fish into the nets.A cottager who lived close by came and complained that the Fisherman was disturbing the stream and making the water too muddy to drink."I am sorry that this bothers you, " replied the Fisherman, "but it is by troubling the waters that I gain my living.
