Description: 这是用 Farseer 物理引擎制作的一个小游戏。玩法特别简单：用鼠标控制白球的位置，尽量不要让白球碰到黑球。距离中心越远，得分越少。
作者项目中遇到的问题：
*模拟环境和显示环境使用的长度单位不一致，需要对两者的单位进行转换。我这里使用的是 ConvertUnits 类进行转换的。
*Farseer 引擎默认设置物体运行速度是不能超过 64 的。可以在源码的 *Settings.MaxTranslation 设置此参数。
*Farseer 引擎具有自动适应功能。长时间没有操作的时候可能会进入“休眠”状态。
*默认物体碰撞是非弹性碰撞。可以通过设置 x.Body.Restitution 来决定是弹性碰撞(1)还是非弹性碰撞(0)，或者介于两者之间。-This is made with Farseer Physics Engine is a small game. Play particularly simple: use the mouse to control the position of the white ball, try not to let the white ball hit the black ball. Farther from the center, scoring less.
Problems encountered by the project:
* Simulation environment and show environment is inconsistent with the length of the unit, both units need to be converted. I am using here is ConvertUnits class conversion.
* Farseer engine speed of an object is the default setting can not exceed 64. In the source* Settings.MaxTranslation set this parameter.
* Farseer engine with automatic adaptation function. Long time no action may be to "sleep" state.
* Default object collisions inelastic collision. Can be determined by setting x.Body.Restitution elastic collision is (1) or non-elastic collisions (0), or somewhere in between. Platform: |

Description: 本实例是一个类似于游戏的弹球程序，程序运行后，黄色的小球在白色的框架内做直线运动。当运动到框架的边界时，与框架发生弹性碰撞，弹回后继续运动。在程序运行过程中，可以调节小球运动速度的快慢，并且可以暂停。-This example is a similar game of pinball program, the program is running, the yellow ball in the white within the framework of linear motion. When the movement to the frame boundary, elastic collisions with the framework to continue the movement after the bounce. In the program is running, you can adjust the motion speed of the ball, and can be suspended. Platform: |

Description: 利用matlab对卢瑟福散射进行仿真。但是因为电子质量很小，而且a粒子和电子的碰撞近似为完全弹性碰撞（因为这种碰撞能量很小，不会发生能级间的跃迁），根据动量守恒和能量守恒可以知道，a粒子速度几乎不变，对实验的结果影响很小。电子如果被撞到的话，估计就会被撞飞了吧，也可能被a粒子或者靶中其他失去电子的阳离子俘获.利用平方反比有心力场中的第三运动积分—Runge-Lenz矢量,简化处理了卢瑟福散射、氢原子的量子化和氢原子园轨道的相对论修正问题.(221/5000
Matlab is used to simulate rutherford scattering. But because electronic quality is small, and particle collisions and electronic approximation for a completely elastic collision (because of the collision energy is very small, do not happen the transition between energy levels), according to the conservation of momentum and conservation of energy, can know a particle velocity is almost the same, little impact on the results of the experiment. Electronic, if be hit, estimates will be flying, may also be a particle or other loss in the target electronic cationic capture. Using the inverse square integral - Runge - Lenz, intentional force field in the third movement vector, simplify the processing the rutherford scattering, hydrogen atoms quantization and orbital relativistic correction problem) Platform: |
