摘　　要：对流体力学的基本原理进行了系统表述,应用伯努利方程及其流速增加压强降低原理,对铁路提速中安全防护的必要性提供了一项理论估算。This paper systematically expounds the basic principles of hydrodynamics and gives a kind of theoretical estimate on the necessity of safety and protection in large train - acceleration by the application of BernouUi Equation and its principle of pressure reduction from fluid velocity increment.

关 键 词：伯努利方程 流速 压强
