简介：为AUV模拟和控制目的提供一个合适的模型，包括水动力学建模的一个新奇推进器的一个一般非线性的动态模型被导出。基于当模特儿的方法，AUV-XX模拟站台被建立在它的运动特征，稳定性，和可控制性上执行基本测试。在一架水平飞机由位置和速度控制组成的运动控制策略为不同任务任务被设计在水下车辆。当车辆以高速度是动人的时，举和沥青的联合控制被采用补偿垂直隧道推进器的减小。一个改进S表面控制器基于电容器板模型被开发，灵活获得选择由限制错误并且改变错误的率的不同形式成为可能。模拟结果证明和模拟站台的导出的一般数学模型能为运动控制的基本测试提供一张测试床。另外，电容器板模型S表面控制在指导车辆与足够的精确性完成需要的位置和速度显示出好表演。

简介：由MAaterialDesign引发的思考：拟物or扁平？一直以来，在潜意识当中，我们会把屏幕内的世界从现实世界中独立出来，我们是通过屏幕这个窗口来窥探那边的世界。在屏幕内，世界运行着一套与现实物理世界完全不一样的规律，这个世界里面没有距离和重量；力的作用也不再那么明显，所以任何东西都可以瞬间出现和消失，可以任意融合与分离。
