A young boy was playing with a ball in the street.He kicked it too hard,and it broke the window of a house and fell inside.A lady came to the window with the ball and shouted at the boy,so he ran away,but he still wanted his ball back.A few minutes later he returned and knocked at the door of the house,and when the lady answered it,he said, "My father is going to come and fix your window very soon." 相似文献

Presto the wizard (巫师) ran into the room with his magic ball and said, "I saw him! I saw Paws!"* The others (其他人) were very excited*. They came to look into the magic ball. "What are you looking for* in my ball?" asked Presto."Paws, of course*!" they answered. "In my magic ball? But I saw him through (通过) the window." Paws walked through the door. "Paws, we are so glad to see you!" Everyone was very happy. 相似文献

Rotor systems supported by angular contact ball bearings are complicated due to nonlinear Hertzian contact force. In this paper, nonlinear bearing forces of ball bearing under five-dimensional loads are given, and 5-DOF dynamic equations of a rigid rotor ball bearing system are established. Continuation-shooting algorithm for periodic solutions of the nonlinear non-autonomous dynamic system and Floquet multipliers of the system are used. Furthermore, the bifurcation and stability of the periodic motion of the system in different parametric domains are also studied. Results show that the bifurcation and stability of period-1 motion vary with structural parameters and operating parameters of the rigid rotor ball bearing system. Avoidance of unbalanced force and bending moment, appropriate initial contact angle, axial load and damping factor help enhance the unstable rotating speed of period-1 motion. 相似文献

A、Michael JordanMichael Jordan is widely thought to be the best basketball player ever. Because he seems to fly through the air with the ball, he's commonly called "Air Jordan" . He became popular even with people who don't usually watch basketball games. Businesses are willing to pay him tens of millions of dollars for his help to sell the things they have made.Michael Jordan is in his thirties. He joined the Chica- 相似文献

It was late. I couldn’t sleep. I stood at my window and looked out into the sky. I saw a shiny dot ( 发光的小圆点) land* on my windowsill ( 窗台 ) . It grew* bigger and bigger and turned into a ball of light.* I watched. The ball turned into a body and a face. It was a boy. He was small and white. 文∕Barbara Brennerland 相似文献

Wire race ball bearings have been widely used in high-tech weapons. The preload of a wire race ball bearing is crucial in engineering applications. In this study, a more effective approach is proposed for exact determination of the wire race ball bearing preload. A new mathematical model of the preload and the starting torque of the wire race ball bearing was built using the theorem of the 3D rolling friction resistance and the non-conforming contact theory. Employing a wire race ball bearing with a 1000 mm diameter used in a specific type of aircraft simulating rotary table, the numerical analysis in MATLAB showed that the preload magnitude can be controlled in the range of 130-140 μm. As verification, the experimental results were in agreement with the theoretical results, and confirm the feasibility of this method. This new approach is more exact in the preload range of 1 0-158 μm than that computed by the numerical method reported in our previous work (Shan et al., 2007b). This implies that the present method contributes to more effectively preventing rolling noise, overturning moments and wear of the wire race ball bearing. The current research provides critical technical support for the engineering application of wire race ball beatings with large diameters. 相似文献

Montanelli suffered from the fierce conflict between humanity and divinity in his pursuit of religious belief.As a sacrifice on the altar of God,Montanelli’s tragedy reflects the influence of the religion upon his behaviors,his internal spirit and his tragic destiny in the end.Furthermore,it manifests the cruelty and darkness of the religious rule and the distortion of the humankind in his age. 相似文献
