preface 1\ Study objects of Fluid Mechanics Fluid mechanics is an important branch of modern mechanics It's a science that studies fluid 's balance mechanical movement laws and the interaction between fluid and the objects around it. It mainly ascertains the distribution of speed and pressure energy loss and the interaction force and the moment between fluid and solid Water and air are researched mostly in fluid mechanics. Besides these fluid also includes vapor as work medium in turbine, lube, water which mixing with mud and sand, blood, melting metal and the gas with complicated components coming from burning, plasm under high temperature condition etc

It mainly ascertains the distribution of speed and pressure ,energy loss and the interaction force and the moment between fluid and solid. Water and air are researched mostly in fluid mechanics. Besides these ,fluid also includes vapor as work medium in turbine, lube ,water which mixing with mud and sand, blood, melting metal and the gas with complicated components coming from burning, plasm under high temperature condition etc

论 、流体力学的研究对象 流体力学是近代力学的一大分支,它是研究流体的平衡和机 械运动规律以及流体与周围物体之间相互作用的科学,主要是确」 定流体的速度分布,压强分布与能量损失,以及流体与固体相互 间的作用力与作用力矩。 流体力学中研究得最多的流体是水和空气。除水和空气以外 流体还包括作为汽轮机工作介质的水蒸汽、润滑油、石油、含泥 沙的水体、血液、溶化状态下的金属和燃烧后产生的成分复杂的 气体,高温条件下的等离子体等等

preface 2, Tasks of Fluid mechanics Fluid mechanics is not only an age- old subject, but also a new fashion subject which can be researched on quite widely fields There are many questions about fluid mechanics in these departments such as in aviation, spaceflight, navigation, astronomical weather, physical geography, water conservancy and hydropower, heat energy refrigeration, building construction and environmental protection, petroleum and chemical engineer, transporting air and liquid, combustion and explosion, metallurgy and mining, biology and sea, war industry and nuclear energy. machine building, mechanical engineering etc
