一口体积

In the paper, river and the downstream area of dike are regarded as a whole system, and hydraulic model of coupling 1-D river and gradual dike-break is established, therein the Preissmann implicit difference scheme is applied to Main River, and the FVM is applied to the breach and polder. On the basis of FVM and unstructured grids, TVD ?

本文将河道与堤坝下游区域视为一个整体，对于单一河道采用Preissmann四点隐式差分格式计算，对于溃口及圩区采用有限体积法，建立了一维河道与堤坝渐溃耦联的水力模型，也是一维、二维耦合的水流模型。

In this paper RoboCup Mid-size Robot are the object of study from the two sides of the robot system and the system of multi-robot cooperation, the main research results are as follows: First, this paper reasearches the problom of the hardware and software architecture of Mid-size robots. According to the real-time requirements of the competition, the paper designs the mechanism of omni-direction wheels, which achieves a great improvement on the traditional mechanism of two wheels robot, and a more flexible response. This mechanism can adapt well to the increasingly rapid pace of the competition. In allusion to the mechanism of omni-direction wheels, this paper designs the electrical control system of three nodes in the bottom, which could communicate fast to the laptop with serial port and match the real-time requirements well. According to the problom of hitting power and speed of robot when shooting, this paper designes a motor-driven tongue-shaped spring shooting mechanism, which has a simple mechanical structure, smaller space in size and simple control circuit. This shooting mechanism meets the real-time requirements of the competition better.

本文以RoboCup中型机器人作为研究对象，分别从机器人自身系统和多机器人协作系统两个方面进行了研究，主要研究成果如下：首先，研究了中型机器人的软硬件体系结构问题，针对实时比赛的要求，提出了万向轮机构的设计方案，大大改进了传统两轮机器人结构，动作反应更加灵活，该机构能够很好的适应节奏越来越快的比赛；针对万向轮机构，设计了3节点的底层电机控制系统，它可以通过串口与上层笔记本电脑快速通讯，能够很好的实现实时工作要求；针对机器人射门时击球力量和速度的问题，设计了一套电机驱动的舌形弹簧射门机构，机械结构简单，占用空间体积小，控制电路简单，较好的满足了比赛中实时射门的要求。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
