一、力学学科的性质力学是研究物质机械运动规律的科学,就其学科性质而言,它既是一门基础科学,寻求对机械运动的规律性认识,又是一门技术科学(又称工程科学),紧密结合解决生产实践中提出的问题。拿湍流理论来说,它研究流体中发生不规则的随机脉动的机理及其结构和演化规律,这是一项基础研究。然而它有很广泛的应用,如:研究一些特殊的大气湍流现象的发生和发展,从而可以提高气象预报水平;它研究如何利用湍流的规律降低飞行器的阻力、提高燃烧效率,以及处理空气和水流中的污染问题等。作为技术科学,力学又有别于具体的工程技术。它灵活地运用其它基础学科的理论,研究存在于广泛工程技术中的共同性问题,偏重于探求规律性的认识,更多从探讨问题的本质、事物的机理人手。事实上,在许多领域中,人们在取得规律性
First, the nature of the mechanical discipline Mechanical mechanics is the study of the laws of the movement of matter machinery science, its nature as a discipline, it is both a basic science, to seek regularity of mechanical movement, but also a technical science (also known as Engineering Science ), Closely combine to solve the problems raised in production practice. Take turbulent theory, it studies the mechanism of irregular random fluctuations in the fluid and its structure and evolution, which is a basic research. However, it has a wide range of applications, such as studying the occurrence and development of some special atmospheric turbulence phenomena, which can improve the weather forecasting level. It studies how to utilize the law of turbulence to reduce the resistance of the aircraft, improve the combustion efficiency, and handle air and water flow In the pollution problems. As a technical science, mechanics are different from the specific engineering. It flexibly uses other basic disciplinary theories to study common problems existing in a wide range of engineering techniques, emphasizing the exploration of regularity, and more from exploring the nature of problems and the mechanics of things. In fact, people are getting regularity in many fields
